I have a notes model. Which has a polymorphic 'noteable' method that ideally anything can use. Probably up to 5 different models such as Customers, Staff, Users etc can use.
I'm looking for the best possible solution for creating the note against these, as dynamically as possible.
At the moment, i'm adding on a query string in the routes. I.e. when viewing a customer there's an "Add Note" button like so:
route('note.create', ['customer_id' => $customer->id])
In my form then i'm checking for any query string's and adding them to the post request (in VueJS) which works.
Then in my controller i'm checking for each possible query string i.e.:
if($request->has('individual_id'))
{
$individual = Individual::findOrFail($request->individual_id_id);
// store against individual
// return note
}elseif($request->has('customer_id'))
{
$customer = Customer::findOrFail($request->customer_id);
// store against the customer
// return note
}
I'm pretty sure this is not the best way to do this. But, i cannot think of another way at the moment.
I'm sure someone else has come across this in the past too!
Thank you
In order to optimize your code, dont add too many if else in your code, say for example if you have tons of polymorphic relationship then will you add tons of if else ? will you ?,it will rapidly increase your code base.
Try instead the follwing tip.
when making a call to backend do a maping e.g
$identifier_map = [1,2,3,4];
// 1 for Customer
// 2 for Staff
// 3 for Users
// 4 for Individual
and so on
then make call to note controller with noteable_id and noteable_identifier
route('note.create', ['noteable_id' => $id, 'noteable_identifier' => $identifier_map[0]])
then on backend in your controller you can do something like
if($request->has('noteable_id') && $request->has('noteable_identifier'))
{
$noteables = [ 'Customers', 'Staff', 'Users','Individual']; // mapper for models,add more models.
$noteable_model = app('App\\'.$noteables[$request->noteable_identifier]);
$noteable_model::findOrFail($request->noteable_id);
}
so with these lines of code your can handle tons of polymorphic relationship.
Not sure about the best way but I have a similar scenario to yours and this is the code that I use.
my form actions looks like this
action="{{ route('notes.store', ['model' => 'Customer', 'id' => $customer->id]) }}"
action="{{ route('notes.store', ['model' => 'User', 'id' => $user->id]) }}"
etc..
And my controller looks this
public function store(Request $request)
{
// Build up the model string
$model = '\App\Models\\'.$request->model;
// Get the requester id
$id = $request->id;
if ($id) {
// get the parent
$parent = $model::find($id);
// validate the data and create the note
$parent->notes()->create($this->validatedData());
// redirect back to the requester
return Redirect::back()->withErrors(['msg', 'message']);
} else {
// validate the data and create the note without parent association
Note::create($this->validatedData());
// Redirect to index view
return redirect()->route('notes.index');
}
}
protected function validatedData()
{
// validate form fields
return request()->validate([
'name' => 'required|string',
'body' => 'required|min:3',
]);
}
The scenario as I understand is:
-You submit noteable_id from the create-form
-You want to remove if statements on the store function.
You could do that by sending another key in the request FROM the create_form "noteable_type". So, your store route will be
route('note.store',['noteableClass'=>'App\User','id'=>$user->id])
And on the Notes Controller:
public function store(Request $request)
{
return Note::storeData($request->noteable_type,$request->id);
}
Your Note model will look like this:
class Note extends Model
{
public function noteable()
{
return $this->morphTo();
}
public static function storeData($noteableClass,$id){
$noteableObject = $noteableClass::find($id);
$noteableObject->notes()->create([
'note' => 'test note'
]);
return $noteableObject->notes;
}
}
This works for get method on store. For post, form submission will work.
/**
* Store a newly created resource in storage.
*
* #param \Illuminate\Http\Requests\NoteStoreRequest $request
* #return \Illuminate\Http\Response
*/
public function store(NoteStoreRequest $request) {
// REF: NoteStoreRequest does the validation
// TODO: Customize this suffix on your own
$suffix = '_id';
/**
* Resolve model class name.
*
* #param string $name
* #return string
*/
function modelNameResolver(string $name) {
// TODO: Customize this function on your own
return 'App\\Models\\'.Str::ucfirst($name);
}
foreach ($request->all() as $key => $value) {
if (Str::endsWith($key, $suffix)) {
$class = modelNameResolver(Str::beforeLast($key, $suffix));
$noteable = $class::findOrFail($value);
return $noteable->notes()->create($request->validated());
}
}
// TODO: Customize this exception response
throw new InternalServerException;
}
So I have a Laravel Application, which has many Controllers to handle various aspects of the applications.
Now each controller has various methods. Most of the methods have validations rules defined such as:
$validationArray = [
'id'=>'required|integer',
'status'=>'required|string'
];
$validator = Validator::make($request->all(),$validationArray);
if ($validator->fails()){
return Response::json(['response'=>implode(', ',$validator->messages()->all())],422);
}
Now the following line:
return Response::json(['response'=>implode(', ',$validator->messages()->all())],422);
actually returns whatever is wrong with the validation rules.
My question is: Is there any way to get all possible error messages programmatically?
Of course, one way to do it is going around the rule by rule and make a list manually but there are hundreds of the methods scattered over various controllers.
So, if anyone could point me in the direction of taking all the error messages in some easier way, would be much appreciated.
Thank you in advance!
UPDATE
So to clear further I need a list of all possible errors, like for above code the list will be like:
['id is required', 'id must be an integer', 'status is required', 'status must be an string']
UPDATE 2
Please keep in mind that there are hundreds of methods and also I do not want to change the final response of the method but to have some sort of external script which can help me getting the error messages without interfering with the controllers much.
In order to do that you have to extend Validator class and write a method that will iterate all rules and explicitly add error messages as if they failed.
First, create a new file app\Http\Custom\Validator.php:
<?php
namespace App\Http\Custom;
use Illuminate\Contracts\Validation\Rule as RuleContract;
use Illuminate\Support\MessageBag;
use Illuminate\Validation\ValidationRuleParser;
use Illuminate\Validation\Validator as BaseValidator;
class Validator extends BaseValidator {
/** #var MessageBag */
protected $errorMessages;
/** #var array */
protected $hasExplicitFileErrorMessage;
protected $explicitFileRules = [
'File', 'Image', 'Mimes', 'Mimetypes', 'Dimensions',
];
function availableErrors()
{
$this->errorMessages = new MessageBag();
$this->hasExplicitFileErrorMessage = [];
foreach($this->rules as $attribute => $rules) {
$attribute = str_replace('\.', '->', $attribute);
foreach($rules as $rule) {
[$rule, $parameters] = ValidationRuleParser::parse($rule);
if($rule == '') {
continue;
}
if(($keys = $this->getExplicitKeys($attribute)) &&
$this->dependsOnOtherFields($rule)) {
$parameters = $this->replaceAsterisksInParameters($parameters, $keys);
}
// explicitly add "failed to upload" error
if($this->hasRule($attribute, $this->explicitFileRules) && !in_array($attribute, $this->hasExplicitFileErrorMessage)) {
$this->addFailureMessage($attribute, 'uploaded', []);
$this->hasExplicitFileErrorMessage[] = $attribute;
}
if($rule instanceof RuleContract) {
$messages = $rule->message() ? (array)$rule->message() : [get_class($rule)];
foreach($messages as $message) {
$this->addFailureMessage($attribute, get_class($rule), [], $message);
}
} else {
$this->addFailureMessage($attribute, $rule, $parameters);
}
}
}
return $this->errorMessages->all();
}
function addFailureMessage($attribute, $rule, $parameters = [], $rawMessage = null)
{
$this->errorMessages->add($attribute, $this->makeReplacements(
$rawMessage ?? $this->getMessage($attribute, $rule), $attribute, $rule, $parameters
));
}
// we have to override this method since file-type errors depends on data value rather than rule type
protected function getAttributeType($attribute)
{
if($this->hasRule($attribute, $this->explicitFileRules)) {
return 'file';
}
return parent::getAttributeType($attribute);
}
}
Next, let's register this class in Validation factory:
<?php
namespace App\Providers;
use App\Http\Custom\Validator; // <-- our custom validator
use Illuminate\Support\ServiceProvider;
class AppServiceProvider extends ServiceProvider {
public function boot()
{
app('validator')->resolver(function ($translator, $data, $rules, $messages) {
return new Validator($translator, $data, $rules, $messages);
});
}
}
And... that's all. Let's test it:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;
class HomeController extends Controller {
function index(Request $request)
{
$rules = [
'id' => 'required|int|between:2,10',
'status' => 'required_with:nonexisting|string|email',
'avatar' => 'required|file|mimes:png|max:1000',
'company' => 'required_without:id|unique:companies,id'
];
$validator = Validator::make([], $rules);
dump($validator->availableErrors());
}
}
array:13 [▼
0 => "The id field is required."
1 => "The id must be an integer."
2 => "The id must be between 2 and 10."
3 => "The status field is required when nonexisting is present."
4 => "The status must be a string."
5 => "The status must be a valid email address."
6 => "The avatar failed to upload."
7 => "The avatar field is required."
8 => "The avatar must be a file."
9 => "The avatar must be a file of type: png."
10 => "The avatar may not be greater than 1000 kilobytes."
11 => "The company field is required when id is not present."
12 => "The company has already been taken."
]
It isn't pretty but here's my shot:
$validationArray = [
'id'=>'required|integer',
'status'=>'required|string'
];
$validator = Validator::make($request->all(), $validationArray);
if ($validator->fails()) {
$messages = [];
$invalid_fields = array_keys($validator->messages()->toArray());
$rules = $v->getRules();
foreach($invalid_fields as $invalid_field) {
foreach($rules[$invalid_field] as $rule) {
if(str_contains($rule, ':') {
// complex rules that have parameters (min, between, size, format)
// are more difficult to work with. I haven't figured out how to do them yet
// but you should get the idea.
continue;
} else {
$messages[] = str_replace(':attribute', $invalid_field, $validator->getTranslator()->get("validation.$rule"));
}
}
}
return Response::json(['response' => implode(', ', $messages)], 422);
}
Number 1: Like I mentioned in my comment under the question, what you're trying to achieve may be done in simpler way.
Number 2: Since you do not want to change your already written code where you got ->messages() then you could do the following. I will list the steps and provide an example code.
We need to override Laravel's validator, (Validation) Factory, and ValidationService provider classes.
In App\Services folder you can create two classes Validator and ValidationFactory
in App\Providers create a class ValidationServiceProvider
Go into config/app.php file and under providers replace Illuminate\Validation\ValidationServiceProvider::class with App\Providers\ValidationServiceProvider::class
Validator class looks like so:
namespace App\Services;
use Illuminate\Support\MessageBag;
use Illuminate\Validation\ValidationRuleParser;
use Illuminate\Contracts\Translation\Translator;
use Symfony\Component\HttpFoundation\File\UploadedFile;
use Illuminate\Contracts\Validation\Rule as RuleContract;
class Validator extends \Illuminate\Validation\Validator
{
/**
* #var MessageBag $all_messages
*/
protected $all_messages;
public function __construct(Translator $translator, array $data, array $rules, array $messages = [], array $customAttributes = [])
{
parent::__construct($translator, $data, $rules, $messages, $customAttributes);
$this->all_messages = new MessageBag;
$this->getAllFormattedMessages();
}
public function makeAllRulesMessages($attribute, $rule, $parameters)
{
$this->all_messages->add($attribute, $this->makeReplacements(
$this->getMessage($attribute, $rule), $attribute, $rule, $parameters
));
}
public function messages(bool $validated_rules_messages = false)
{
return $validated_rules_messages
? $this->validatedMessages()
: $this->all_messages;
}
/**
* This is here in case the true validated messages are needed
*
* #return MessageBag
*/
public function validatedMessages()
{
return parent::messages();
}
public function getAllFormattedMessages()
{
// We'll spin through each rule and add all messages to it.
foreach ($this->rules as $attribute => $rules) {
$attribute = str_replace('\.', '->', $attribute);
foreach ($rules as $rule) {
// First we will get the correct keys for the given attribute in case the field is nested in
// an array. Then we determine if the given rule accepts other field names as parameters.
// If so, we will replace any asterisks found in the parameters with the correct keys.
[$rule, $parameters] = ValidationRuleParser::parse($rule);
if (($keys = $this->getExplicitKeys($attribute)) &&
$this->dependsOnOtherFields($rule)) {
$parameters = $this->replaceAsterisksInParameters($parameters, $keys);
}
$value = $this->getValue($attribute);
if ($value instanceof UploadedFile && $this->hasRule($attribute, array_merge($this->fileRules, $this->implicitRules))
) {
$this->makeAllRulesMessages($attribute, 'uploaded', []);
} elseif ($rule instanceof RuleContract) {
$this->makeCustomRuleMessage($attribute, $rule);
} else {
$this->makeAllRulesMessages($attribute, $rule, $parameters);
}
}
}
}
/**
* #param $attribute
* #param \Illuminate\Contracts\Validation\Rule $rule $rule
*/
public function makeCustomRuleMessage($attribute, $rule)
{
$this->failedRules[$attribute][get_class($rule)] = [];
$messages = (array)$rule->message();
foreach ($messages as $message) {
$this->all_messages->add($attribute, $this->makeReplacements(
$message, $attribute, get_class($rule), []
));
}
}
}
This class does one thing in summary, get all the messages of the passed rules into $all_messages property of the class. It extends and allows the base validation class run, and simply overrides messages() method to make all the collected rules available for use.
ValidationFactory overrides Illuminate\Validation\Factory and it looks like so:
namespace App\Services;
use Illuminate\Validation\Factory;
class ValidationFactory extends Factory
{
/**
* Resolve a new Validator instance.
*
* #param array $data
* #param array $rules
* #param array $messages
* #param array $customAttributes
* #return \Illuminate\Validation\Validator
*/
protected function resolve(array $data, array $rules, array $messages, array $customAttributes)
{
if (is_null($this->resolver)) {
return new \App\Services\Validator($this->translator, $data, $rules, $messages, $customAttributes);
}
return call_user_func($this->resolver, $this->translator, $data, $rules, $messages, $customAttributes);
}
}
This class does only one thing, overrides resolve() method in this class by making use of the instance of our custom \App\Services\Validator class instead.
ValidationServiceProvider extends Illuminate\Validation\ValidationServiceProvider and overrides registerValidationFactory() method and it looks like so:
namespace App\Providers;
use App\Services\ValidationFactory;
use Illuminate\Validation\ValidationServiceProvider as BaseValidationServiceProvider;
class ValidationServiceProvider extends BaseValidationServiceProvider
{
protected function registerValidationFactory()
{
$this->app->singleton('validator', function ($app) {
$validator = new ValidationFactory($app['translator'], $app);
// The validation presence verifier is responsible for determining the existence of
// values in a given data collection which is typically a relational database or
// other persistent data stores. It is used to check for "uniqueness" as well.
if (isset($app['db'], $app['validation.presence'])) {
$validator->setPresenceVerifier($app['validation.presence']);
}
return $validator;
});
}
}
What the above class does is also to instruct the provide to make use of our App\Services\ValidationFactory whenever the app requires one.
And we are done. All validation messages will be shown even if one of our validation rules failed.
Caveats
In order to achieve this, we needed to make a lot of changes and overriding. Except really critical this may signal that something about the app's design looks wrong.
Laravel validation implementation may change in future release and therefore may become a problem maintaining these changes.
I cannot tell if there are other side effects that might happen for overriding Laravel's default validation implementation or if all the rules return the right messages.
Normally you only want to return failed validation messages to user rather than all the possible failures.
I think that functions failed() (get the failed validation rules) or errors() (get the message container for the validator) may help you. If it does not - go to https://laravel.com/api/5.8/Illuminate/Validation/Validator.html and I hope that you find needed function.
I think you are looking for a way to have custom error messages. if this is the case then the answer is like this:
$messages = [
'id.required' => 'id is required',
'id.integer' => 'id must be an integer',
'status.required' => 'status is required',
'status.string'=> 'status must be an string'
];
$validationArray = [
'id'=>'required|integer',
'status'=>'required|string'
];
$validator = Validator::make($request->all(),$validationArray, $messages);
more info you can find here.
I hope this is what you are looking for and my answer is helping you:)
Based on the Laravel Form Validation Procedure you can write the statement by following:
$validationArray = [
'id'=>'required|integer',
'status'=>'required|string'
];
$validator = Validator::make($request->all(),$validationArray);
if ($validator->fails()){
return Response::json(['response'=> validator->errors())],422);
}
Where errors() method return all the errors as associative array where the message will be associate with the field name accordingly and that's how you can get the errors.
In my CI4 learning, I have started by trying to simulate user sign in functionality. I have a Controller, two Views (not shown here, but really simply pages- one a pretty much just single form, and the other one a “blank” success HTML page), a set of custom rules in the Validation.php file, and a CustomRule.php file with the first of the methods that will implement all my custom rules (which, ultimately, I’d like to have all set in the Validation.php file). For lack of a better idea, I’ve stuck the CustomRules.php file in the app\Config\ folder.
Here is my problem:
For the life of me, I can’t figure out how to get the Validation service to pass additional parameters (from the form) to my custom rules function called ‘user_validated’. The CI4 documentation describes what the custom function needs to cater for when accepting additional parameters, but not how to trigger the Validation service to pass these additional parameters to one’s custom function… so although ‘user_validated’ is called, only ‘user_email_offered’ is ever passed as in as a string- nothing else goes in, from what I can tell. How do I get around this?
I have tried inserting < $validation->setRuleGroup('user_signin'); > before the call to validate, but found that I could move the setting of the rule group into the call to validate, using: $validationResult = $this->validate('user_signin'), which seemed to do the same, and which doesn't seem to work without the rule-group as a parameter (?). This still doesn't seem to be what triggers the additional data to be passed to the custom rule's method.
Extracts from my hack are appended below.
I’d be very grateful one of you knowledgeable folk could please point me in the right direction.
In app\Controllers\SignupTest.php:
<?php
namespace App\Controllers;
use CodeIgniter\Controller;
class SignupTest extends BaseController
{
public function index() { // redirection from the default to signup(), signin(), ...
return $this->signup();
}
public function signup() {
helper(['form']);
$validation = \Config\Services::validation();
if ($this->request->getPost()) { // still TBD: any different to using $this->request->getGetPost() ?
$validationResult = $this->validate('user_signin'); // set the rules to use: 'user_signin', 'user_signup'
if (!$validationResult) {
$validationErrors = $validation->getErrors();
return view('SignupTestView', $validationErrors); // redisplay simple html form view with list of validation errors
} else {
return view('SignupTestViewSuccess'); // display view to show success
}
} else {
return view('SignupTestView'); // initial display, in the event of there being no POST data
}
}
}
In \app\Config\CustomRules.php:
<?php
namespace Config;
use App\Models\UserModel;
//--------------------------------------------------------------------
// Custom Rule Functions
//--------------------------------------------------------------------
class CustomRules
{
public function user_validated(string $str, string $fields = NULL, array $data = NULL, string &$error = NULL) : bool{
$user_email_offered = $str;
$user_password_offered = ''; // to be extracted using $fields = explode(',', $fields), but $fields is never provided in the call to this user_validated method
if (($user_email_offered !== NULL) && ($user_password_offered !== NULL)) {
$usermodel = new UserModel(); // intended to create a UserEntity to permit connectivity to the database
$user_found = $usermodel->find($user_email_offered); // we're going to assume that user_email is unique (which is a rule configured in the database table)
if ($user_found === NULL) { // check if user exists before doing the more involved checks in the else-if section below, which may throw exceptions if there's nothing to compare (?)
...
}
}
In \app\Config\Validation.php:
?php
namespace Config;
class Validation
{
//--------------------------------------------------------------------
// Setup
//--------------------------------------------------------------------
/**

* rules that are available.

const user_email_max_lenth = 50;
const user_password_min_lenth = 6;
const user_password_max_lenth = 25;
public $user_signin = [
'user_email' => [
'label' => 'e-mail address',
'rules' => 'trim|required|valid_email|user_validated', // user_validated is custom rule, that will have a custom error message
'errors' => [
'required' => 'You must provide an {field}',
'valid_email' => 'Please enter a valid {field}',
]
],
'user_password' => [
'label' => 'password',
'rules' => 'trim|required',
'errors' => [
'required' => 'Enter a {field} to sign in',
'user_password_check' => 'No such user/{field} combination found',
]
Calling custom rule with parameters should be exactly the same as calling CI4's regular rules. Let's get for example "required_without". You use it like in this example:
$validation->setRule('username', 'Username', 'required_without[id,email]');
And the function is declared as so:
public function required_without($str = null, string $fields, array $data): bool
{
$fields = explode(',', $fields);
//...
}
where $str - this is your main field, $fields - string, packing a comma-separated array.
As for Grouping rules, you do not need to group rules to be able to use custom rules with parameters.
If you have only 2 fields to test against you can go a bit cheaper, which will not be perfect but still works:
Function:
public function myrule(string $mainfield, string $fieldtotestwith): bool
{
//doing stuff
}
Validating rule:
$validation->setRule('somemainfield', 'Something', 'myrule[somesecondfield]');
I tried to look up on Google but didn't find anyone with such a problem. I think I did everything like the documentation guides but I guess I'm missing something
So I have a form with checkbox like this:
$builder->add(
'productTypes',
EntityType::class,
array(
'label' => 'Available for products',
'class' => 'ShopBundle:ProductType',
'choice_label' => 'name',
'multiple' => true,
'expanded' => true,
'by_reference' => false,
)
);
When I'm editing everything goes smooth, I can edit existing entry and check or uncheck this checkbox, it saves properly, but when I try to add new Object I get error:
PHP Fatal error: Call to a member function add() on null in
C:\xampp\htdocs\uniacar-sf\src\ShopBundle\Entity\ProductAttribute.php
on line 188
This is my controller action:
public function editAction(Request $request, $id = null)
{
$this->setMenuTab('cars', 'admin');
$productTypes = new ArrayCollection();
if (!empty($id)) {
$attribute = $this->getRepo(ProductAttribute::class)->find($id);
$this->setTitle('admin.cars.attributes.edit');
foreach ($attribute->getProductTypes() as $value) {
$productTypes->add($value);
}
} else {
$attribute = new ProductAttribute();
$this->setTitle('admin.cars.attributes.new');
}
$form = $this->createForm(ProductAttributeForm::class, $attribute);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$attribute = $form->getData();
foreach ($productTypes as $productType) {
if (false === $attribute->getProductTypes()->contains($productType)) {
$productType->getAttributes()->removeElement($attribute);
$this->db()->persist($productType);
}
}
$this->db()->persist($attribute);
$this->db()->flush();
return $this->redirectToRoute('carAdmin', array('tab' => 'attributes'));
}
$this->setVariables(
array(
'form' => $form->createView(),
'attribute' => $attribute,
)
);
return $this->response();
}
$this->db() is my shortcut for $this->getDoctrine()->getManager()
And this is definition part of ProductAttribute that relates to ProductType:
/**
* Constructor
*/
public function __construct() {
$this->productTypes = new ArrayCollection();
}
/**
* Many Attributes have Many ProductTypes
* #ORM\ManyToMany(targetEntity="ProductType", mappedBy="attributes", cascade={"persist"})
*/
private $productTypes;
/**
* #param ProductType $productType
*/
public function addProductType(ProductType $productType)
{
$this->productTypes->add($productType);
$productType->addProductAttribute($this);
}
/**
* #param ProductType $productType
*/
public function removeProductType(ProductType $productType)
{
$this->productTypes->removeElement($productType);
}
Also there is part of ProductType Entity that relates to ProductAttribute:
/**
* Constructor
*/
public function __construct() {
$this->attributes = new ArrayCollection();
}
/**
* Many ProductTypes have Many Attributes
* #ORM\ManyToMany(targetEntity="ProductAttribute", inversedBy="productTypes")
* #ORM\JoinTable(name="product_type_to_attribute")
*/
private $attributes;
/**
* #param ProductAttribute $attribute
*/
public function addProductAttribute(ProductAttribute $attribute)
{
if (!$this->attributes->contains($attribute)) {
$this->attributes->add($attribute);
}
}
public function removeProductAttribute(ProductAttribute $attribute)
{
$this->attributes->removeElement($attribute);
}
I tried to follow Symfony Embed Form Tutorial (How to Embed a Collection of Forms)
I know that in this case there is no embeded collection (I have another field in this Entity, that is embeded collection of forms and it works just fine) but from what I understand relations are the same in this case, it's many to many so I have to tell the Symfony how to treat relations, add and remove objects.
I dumped data that comes in POST but it's the same as for edition - productType is there. Any ideas why do I get this error?
It fires in ProductAttribute Entity in the line $this->productTypes->add($productType);
EDIT:
I updated the controller code, I messed up the logic about unlinking ProductType from ProductAttribute. But it doesn't have any impact on the problem, still the same 500 error when I try to save new object.
EDIT2:
I can't get stack trace from Symfony because I get ordinary browser 500 error (probably because it's Fatal Error, I found it in apache logs). The line in controller which creates error is $form->handleRequest($request);.
This is not a Collection of Forms, but you are using collection specific method, this is not a good practice, however, you don't need this below code when you create a new object.
foreach ($productTypes as $value) {
if (false === $attribute->getProductTypes()->contains($value)) {
$attribute->getProductTypes()->removeElement($value);
}
}
So, I haven't found solution to the problem but I solved it somehow by fixing file structure of my project (moved bundle's Resources from general Resources folder to Bundle's Resources folder). I have no idea why this fixed the issue and what is even the connection between working but not proper folder structure and submitting forms but now it works, so I will mark the question as answered.

Improve this question
I have my custom Request, which extends the Backpack CrudController.
Now I would like to override the prepareForValidation of the ValidatesWhenResolvedTrait since it looks like the right place to modify my incoming data, but I can't figure out how ...
So my first question is, can I override this method? Its protected ...
protected function prepareForValidation()
And my second question, how can I modify my input on the Request or FormRreuqest objects?
Here is my RequestClass
<?php
namespace App\Http\Requests;
use App\Http\Requests\Request;
use Config;
class DonationsRequest extends \Backpack\CRUD\app\Http\Requests\CrudRequest
{
/**
* Determine if the user is authorized to make this request.
*
* #return bool
*/
public function authorize()
{
// only allow updates if the user is logged in
return \Auth::check();
}
/**
* Get the validation rules that apply to the request.
*
* #return array
*/
public function rules()
{
return [
'name' => 'required|max:255',
'email' => 'required|email',
'dob' => 'required|date',
'newsletter' => 'required|boolean',
'country' => 'sometimes|required|in:'.implode(',', Config::get('validation.countries')),
'street' => 'sometimes|required|string|max:255',
'zip' => 'sometimes|required|string|between:4,5',
'city' => 'sometimes|required|string|between:4,255',
'amount' => 'required|numeric|between:1,'.Config::get('donations.max'),
'type' => 'required|in:oo,monthly',
'provider' => 'sometimes|string|nullable',
'product_id' => 'sometimes|exists:products,id|nullable',
'campaign_id' => 'required|exists:campaigns,id',
'status' => 'sometimes|required|in:pending,canceled,success,error',
'profile' => 'sometimes|string|regex:/^profile[0-9]+$/|nullable',
];
}
/**
* Get the validation attributes that apply to the request.
*
* #return array
*/
public function attributes()
{
return [
//
];
}
/**
* Get the validation messages that apply to the request.
*
* #return array
*/
public function messages()
{
return [
//
];
}
private function prepareForValidation()
{
dd('getValidatorInstance custom');
$this->sanitizeInput();
return parent::getValidatorInstance();
}
private function sanitizeInput()
{
dd('sanitizeInput custom');
$data = $this->all();
dd($data);
// overwrite the newsletter field value to match boolean validation
$data['newsletter'] = ($data['newsletter'] == 'true' || $data['newsletter'] == '1' || $data['newsletter'] == true) ? true : false;
return $data;
}
private function validate() {
dd('validate');
}
}
As you can see, I first tried to override the getValidatorInstance method, since this looked like the common aproach to this, but it is not executed (so not overridden - protected?).
Although I didn't tried but it seems it should work you can override validationData from Illuminate\Foundation\Http\FormRequest class like.
/**
* Get data to be validated from the request.
*
* #return array
*/
protected function validationData()
{
$all = parent::validationData();
//e.g you have a field which may be json string or array
if (is_string($playerIDs = array_get($all, 'player_id')))
$playerIDs = json_decode($playerIDs, true);
$all['player_id'] = $playerIDs
return $all;
}
or you can override all method in Illuminate\Http\Concerns\InteractsWithInput trait
/**
* Get all of the input and files for the request.
*
* #return array
*/
public function all()
{
$all = parent::all();
//then do your operation
if (is_string($playerIDs = array_get($all, 'player_id')))
$playerIDs = json_decode($playerIDs, true);
$all['player_id'] = $playerIDs
return $all;
}
Could you modify the request?
$request->merge(['field' => 'new value']);
Well I am sure,this can help in modifying The input, it worked for me.[laravel 5.4]
place this
$input['url'] = $url;
$this->replace($input);
dd($input);
in listFormRequest. (use $all instead of $input, if you follow above used answer).
This only changes input,which is available even in controller. You still need to find a way to insert it into DB, or do something else to use modified input for using it in blade.
Ok I found out where the error was. I did split the Frontend Request and the Backend Request Call. Since I was working on the Backend Request the Frontend Request was not overwriting anything ... so it was my bad, no bug there, sry for the waste of time, but a big thanks to the community!
