I've created a form which adds a category of product in a Categories table (for example Sugar Products or Beer), and each user has their own category names.
The Categories table has the columns id, category_name, userId, created_At, updated_At.
I've made the validation and every thing is okay. But now I want every user to have a unique category_name. I've created this in phpMyAdmin and made a unique index on (category_name and userId).
So my question is this: when completing the form and let us say that you forgot and enter a category twice... this category exist in the database, and eloquent throws me an error. I want just like in the validation when there is error to redirect me to in my case /dash/warehouse and says dude you are trying to enter one category twice ... please consider it again ... or whatever. I am new in laravel and php, sorry for my language but is important to me to know why is this happens and how i solve this. Look at my controller if you need something more i will give it to you.
class ErpController extends Controller{
public function __construct()
{
$this->middleware('auth');
}
public function index()
{
return view('pages.erp.dash');
}
public function getWarehouse()
{
$welcome = Auth::user()->fName . ' ' . Auth::user()->lName;
$groups = Group::where('userId',Auth::user()->id)->get();
return view('pages.erp.warehouse', compact('welcome','groups'));
}
public function postWarehouse(Request $request)
{
$input = \Input::all();
$rules = array(
'masterCategory' => 'required|min:3|max:80'
);
$v = \Validator::make($input, $rules);
if ($v->passes()) {
$group = new Group;
$group->group = $input['masterCategory'];
$group->userId = Auth::user()->id;
$group->save();
return redirect('dash/warehouse');
} else {
return redirect('dash/warehouse')->withInput()->withErrors($v);
}
}
}
You can make a rule like this:
$rules = array(
'category_name' => 'unique:categories,category_name'
);

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;
}
When updating my Post model, I run:
$post->title = request('title');
$post->body = request('body');
$post->save();
This does not update my post. But it should according to the Laravel docs on updating Eloquent models. Why is my model not being updated?
I get no errors.
The post does not get updated in the db.
Besides not being updated in the db, nothing else seems odd. No errors. Behavior as normal.
Result of running this test to see if save succeeded was true.
This Laravel thread was no help
Post model:
class Post extends Model
{
protected $fillable = [
'type',
'title',
'body',
'user_id',
];
....
}
Post controller:
public function store($id)
{
$post = Post::findOrFail($id);
// Request validation
if ($post->type == 1) {
// Post type has title
$this->validate(request(), [
'title' => 'required|min:15',
'body' => 'required|min:19',
]);
$post->title = request('title');
$post->body = request('body');
} else {
$this->validate(request(), [
'body' => 'required|min:19',
]);
$post->body = request('body');
}
$post->save();
return redirect('/');
}
Bonus info
Running dd($post->save()) returns true.
Running
$post->save();
$fetchedPost = Post::find($post->id);
dd($fetchedPost);
shows me that $fetchedPost is the same post as before without the updated data.
Check your database table if the 'id' column is in uppercase 'ID'. Changing it to lower case allowed my save() method to work.
I had the same and turned out to be because I was filtering the output columns without the primary key.
$rows = MyModel::where('...')->select('col2', 'col3')->get();
foreach($rows as $row){
$rows->viewed = 1;
$rows->save();
}
Fixed with
$rows = MyModel::where('...')->select('primary_key', 'col2', 'col3')->get();
Makes perfect sense on review, without the primary key available the update command will be on Null.
I had the same problem and changing the way I fetch the model solved it!
Was not saving even though everything was supposedly working just as you have mentioned:
$user = User::find($id)->first();
This is working:
$user = User::find($id);
You have to make sure that the instance that you are calling save() on has the attribute id
Since Laravel 5.5 laravel have change some validation mechanism I guess you need to try this way.
public function store(Request $request, $id)
{
$post = Post::findOrFail($id);
$validatedData = [];
// Request validation
if ($post->type == 1) {
// Post type has title
$validatedData = $request->validate([
'title' => 'required|min:15',
'body' => 'required|min:19',
]);
} else {
$validatedData = $request->validate([
'body' => 'required|min:19',
]);
}
$post->update($validatedData);
return redirect('/');
}
Running dd() inside a DB::transaction will cause a rollback, and the data in database will not change.
The reason being, that transaction will only save the changes to the database at the very end. Ergo, the act of running "dump and die" will naturally cause the script to cease and no therefore no database changes.
Check your table if primary key is not id ("column name should be in small letters only") if you have set column name with different key then put code in your Model like this
protected $primaryKey = 'Id';
So this might be one of the possible solution in your case also if your column name contains capital letters.
Yes this worked for me fine,
You should have column names in small letter,
If you don't have then mention it in the model file, mainly for primaryKey by which your model will try to access database.
For use save () method to update or delete if the database has a primary key other than "id". need to declare the attribute primaryKey = "" in the model, it will work
Try this
public function store($id,Request $request)
{
$post = Post::findOrFail($id);
// Request validation
if ($post->type == 1) {
// Post type has title
$request->validate([
'title' => 'required|min:15',
'body' => 'required|min:19',
]);
$post->update([
'title' => request('title');
'body' => request('body');
]);
} else {
$request->validate([
'body' => 'required|min:19',
]);
$post->update([
'body' => request('body');
]);
}
return redirect('/');
}
In my experience, if you select an Eloquent model from the db and the primary_key column is not part of the fetched columns, your $model->save() will return true but nothing is persisted to the database.
So, instead of doing \App\Users::where(...)->first(['email']), rather do \App\Users::where(...)->first(['id','email']), where id is the primary_key defined on the target table.
If the (sometimes micro-optimization) achieved by retrieving only a few columns is not really of importance to you, you can just fetch all columns by doing \App\Users::where(...)->first(), in which case you do not need to bother about the name of the primary_key column since all the columns will be fetched.
If you using transactions.
Do not forget call DB::commit();
It must look like this:
try{
DB::beginTransaction();
// Model changes
$model->save();
DB::commit();
}catch (\PDOException $e) {
DB::rollBack();
}
I have the same issue although there are try / catch block in controller#action() but there were no response, it just stops at $model->save(); there is no log entry either in apache error.log or laravel.log. I have just wrapped the save() with try / cactch as follows, that helped me to figure out the issue
try{
$model->save();
}
catch (\PDOException $e) {
echo $e->getMessage();
}
I have been experiencing the same issue and found a workaround. I found that I was unable to save() my model within a function called {{ generateUrl() }} on my home.blade.php template. What worked was moving the save() call to the controller that returns the home.blade.php template. (IE, save()ing before the view is returned, then only performing read operations within {{ generateUrl() }}.)
I was (and am) generating a state to put in a URL on page load:
<!--views/home.blade.php-->
Add Character
Below is what did not work.
// Providers/EveAuth.php
function generateUrl()
{
$authedUser = auth()->user();
if (!$authedUser) {
return "#";
}
$user = User::find($authedUser->id);
$user->state = str_random(16);
$user->save();
$baseUrl = 'https://login.eveonline.com/oauth/authorize?state=';
return $baseUrl . $user->state;
}
This was able to find() the User from the database, but it was unable to save() it back. No errors were produced. The function appeared to work properly... until I tried to read the User's state later, and found that it did not match the state in the URL.
Here is what did work.
Instead of trying to save() my User as the page was being assembled, I generated the state, save()d it, then rendered the page:
// routes/web.php
Route::get('/', 'HomeController#index');
Landing at the root directory sends you to the index() function of HomeController.php:
// Controllers/HomeController.php
public function index()
{
$authedUser = auth()->user();
if ($authedUser) {
$user = User::find($authedUser->id);
$user->state = str_random(16);
$user->save();
}
return view('home');
}
Then, when generating the URL, I did not have to save() the User, only read from it:
// Providers/EveAuth.php
function generateUrl()
{
$authedUser = auth()->user();
$user = User::find($authedUser->id);
$baseUrl = 'https://login.eveonline.com/oauth/authorize?state=';
return $baseUrl . $user->state;
}
This worked! The only difference (as far as I see) is that I'm save()ing the model before page assembly begins, as opposed to during page assembly.
I'm working on L5.5 and I need to delete user but not his/her posts. So I basically need to assign his/her posts to another user which has to be Non-removable.
What I need:
Create a user which can't be deleted at least not from front-end even by owner of website but can be edited. (mostly is like bot for this application)
If I delete a user and that user had post(s) those post(s) remain and assign to this user (bot). It means this bot will become author of those posts.
Check for number 2 that only if user with post that happens if user has no post just delete him/her.
This is my usecontroller destroy method currently:
public function destroy($id)
{
$user = User::findOrFail($id);
Storage::delete($user->image);
$user->delete();
return redirect()->route('users.index')->with('flash_message', 'User successfully deleted');
}
Thanks.
According to your needs, you will require softDeletes in your User model and their respective tables in the database, now this solves your 1st problem where your not deleting the user from table simply adding deleted_at column.
Edit: As you are using Zizaco\Entrust\Traits\EntrustUserTrait you need to have your user model look something like this:
class User extends Model implements AuthenticatableInterface
{
use Authenticatable;
use EntrustUserTrait { restore as private restoreA; }
use SoftDeletes { restore as private restoreB; }
public function restore()
{
$this->restoreA();
$this->restoreB();
}
}
For more information about this error you need to look: https://github.com/Zizaco/entrust/issues/742
so now coming to the 2nd point, retrieving the post with deleted model can be used withTrashed() something like:
$user = User::withTrashed()->all();
$user = User::withTrashed()->where('id', 1);
$posts = $user->posts()->get();
// Or do your relational things
Even if you want to assign it to different user then you need to create a new user and apply update methods to all the relational model while deleting the user which seems a bad idea.
Edit:
So in this case you can have:
$oldUser = User::find($id);
$user = User::find($botID); // Find the bot user
$oldFoods = $oldUser->food()->get();
foreach($oldFoods as $food)
{
$food->user_id = $user->id;
$food->save();
}
Now for your 3rd point if the user has no post then you can do a small check something like this:
$user = User::find($request->id);
$posts = $user->posts()->get()->first();
if(isset($posts))
{
$user->delete();
}
else
{
$user->forceDelete();
}
Hope this justifies all your needs.
Conclusion So fnally you can have your destroy method in userController as:
public function destroy($id)
{
$user = User::findOrFail($id);
$foods = $user->food()->get();
if(isset($foods))
{
$botUser = User::where('username', '=', 'bot'); // Find the bot user
foreach($foods as $food)
{
$food->user_id = $botUser->id;
$food->save();
}
$user->delete();
}
else
{
$user->forceDelete();
}
Storage::delete($user->image);
return redirect()->route('users.index')->with('flash_message', 'User successfully deleted');
}
Edit your database with
$table->integer('user_id')->unsigned();
$table->foreign('user_id')->references('id')->on('users')
->onDelete('restrict')
->onUpdate('restrict');
When i like my own post i will get notification it should not happen,
now what i want is notification should not save in database if like I on my own post,
My controller :
public function store(Request $request,$id)
{
$like = new Like();
$like->user_id =Auth::user()->id;
$like->post_id = $id;
if($like->save())
{
if (Auth::user()->id != $id)
{
$user = User::findOrFail($request->get('user_id'));
Notification::send($user , new likePost($like));
$data = auth()->user()->name.'Liked Your Post '.'<Strong>'.$request->input('title').'</strong'.'<\br>'.'On'.Carbon::now();
StreamLabFacades::pushMessage('test' , 'likePost' , $data);
}
}
Your second argument ($id) is referring to the post ID.
You are saying that if your post_id does not equal your user_id, then send a notification. In this case, there will only ever be one case of this.
I am not sure how your logic is set up, however I imagine you have another Model called Post.
Your logic would go something along the lines of:
public function store(Request $request, $post_id){
$like = Like::create([ 'user_id' => Auth::user()->id, 'post_id' => $post_id]);
$post = Post::whereId($post_id)->first();
if( $post->user_id !== Auth::user()->id ) {
//SEND Notification code here
}
}
A better way of doing this would be to create a relantionship in your Like model that points to your Post model. See here: https://laravel.com/docs/5.4/eloquent-relationships#one-to-many-inverse
In particular the One-to-Many Inverse. They have an example with comments which I think is very similar to your case.
Hope this helps
This is a category table I am using in my project using Laravel.
I have checks applied in the view files, for the category parent selection dropdown, so that the category itself and it's child's will not appear in the dropdown.
But form input fields value can be easily overridden using dev console.
Is there a way in models so that if parent id is equal to the category id itself or parent id is the child of current category then it will stop execution.
I have recently started laravel, a month ago, and still learning and building, so help here will be appreciated.
I was able to resolve the issue by overriding the update method in model -
Controller update method -
public function update(Request $request, $id)
{
$this->validate($request,
['name' => 'required',]);
$data = [];
$data = ['name' => Input::get('name'),
'parent' => !empty(Input::get('parent')) ? Posts_categories::find(Input::get('parent'))->id : NULL,];
$category = Posts_categories::find($id);
if(is_null($category))
{
Session::flash('flash-message', 'Category type with the given id does not exist.');
Session::flash('alert-class', 'alert-warning');
return redirect()->route('admin.post.category.index');
}
if($category->update($data)) {
Session::flash('flash-message', 'Category succesfully updated.');
Session::flash('alert-class', 'alert-success');
}
return redirect()->route('admin.post.category.index');
}
Model update method -
public function update(array $attributes = [], array $options = [])
{
$parent = SELF::find($attributes['parent']);
if($this->id == $parent->id || $this->id == $parent->parent)
{
Session::flash('flash-message', 'Invalid parent selection for category.');
Session::flash('alert-class', 'alert-warning');
return 0;
}
return parent::update($attributes, $options); // TODO: Change the autogenerated stub
}
