I have a dropdown in my Yii form created with CActiveForm->dropDownList.
I am using the array('empty'=>'Please select one') as the way to set the value when nothing is selected.
The field is constrained to another table, but it is set to allow NULL. When Yii shows the MySQL error, it says:
integrity constraint violation: 1452 Cannot add or update a child row: a foreign
key constraint fails (`imi_sales`.`ss_project`, CONSTRAINT
`fk_project_product_type` FOREIGN KEY (`product_type_id`) REFERENCES
`ss_product_type` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION)
It also shows that the value being inserted into ss_project.product_type_id is ''. If I copy the SQL out and change it to NULL, it works. How can I have Yii set it to NULL?
Add the following codes into beforeSave() method:
public function beforeSave(){
if(parent::beforeSave()){
if(empty($this->product_type_id)) {$this->product_type_id=NULL;}
return true;
}
}
By this, you tell Yii before saving new record, check whether product_type_id value is empty('') or not. If yes, set it NULL.
The selected answer works but I believe this is more elegant.
/**
* #return array validation rules for model attributes.
*/
public function rules()
{
// NOTE: you should only define rules for those attributes that
// will receive user inputs.
return array(
....................
array('product_type_id', 'default', 'setOnEmpty' => true, 'value' => null),
....................
);
}

I am trying to ignore a unique role for a given ID but I keep getting the following error:
SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry
'user#updated.com' for key 'users_email_unique' (SQL: update users
set name = Name, email = user#updated.com, updated_at =
2018-04-06 10:01:27 where id = 1)
In my UserUpdateRequest class I have the rules set up:
public function rules()
{
return [
'email' => 'required|email|unique:users,email,' . $this->route()->parameter('user'),
'name' => 'required',
];
}
$this->route()->parameter('user') gets the current model ID.
Not sure what I'm doing wrong with my rules here, anyone have any ideas?
Here is where I am making the call to the update:
public function update(Requests\UserUpdateRequest $request, $id)
{
$result = $this->service->update($request->except(['_token', '_method']));
if ($result) {
return back()->with('message', 'Successfully updated');
}
return back()->with('message', 'Failed to update');
}
DB:
The error comes because you are trying to save a duplicate entry in your database. You can see that in your indexes all e-mails need to be unique.
If you try to change a record to an E-Mail Address that is already used by someone else, you get the integrity constraint error message.
The problem was I was not passing the ID of the user through to the function so it was updating the current logged in user's record instead, as a result it would trigger the unique rule. You can see in the query it was doing WHERE id =1 because it was updating using Auth::id();.
That is a SQL error, you have a unique constraint on sql table. Probably when you made the migration you added table->string("email")->unique()
I want to delete a data in database with delete, but the table doesn't have the primary key
Here's the code
Table::findOne(['name' => 'Andrew', 'Age' => '25'])->delete();
Then, it shows the error
app\models\Table does not have a primary key. You should either define a primary key for the corresponding table or override the primaryKey() method.
Help me to find the way to delete without a primary key.
Thanks
You could override primaryKey() model method, so the error should disappear.
Inside app\models\Table add this method (I think that primary key should be composed with 'name' and 'Age'):
public static function primaryKey()
{
return [
'name',
'Age',
];
}
Instead of using ActiveRecord, you could use a delete command with condition:
$myCommand = Yii::$app->db->createCommand()
->delete('your_table', 'name = "Andrew" AND Age = 25 ');
$myCommand->execute();
If you want to delete all the rows that match the condition, you can use:
deleteAll( ... ) ;
Try This :
$data=Table::find()->where(['name' => 'Andrew', 'Age' => '25'])->one();
$data->delete();
The code below shows a method in my Eloquent Link class. After creating a new Link I want to create a related object LinkContact then associate() it with the new Link.
When creating LinkContact I experience an issue in accessing the Link's id attribute. The Link id value appears inaccessible only when performing the create method for the new related object (LinkContact).
Using Laravel Debugbar a line before the create method is called I've logged the Link id and I can see it just fine! Any ideas why this is happening and why I can't access the value?! Is it to do with scope?
Please take note of where the comments are
public function createActiveLink($students)
{
$links = [];
foreach ($students as $student) {
$newLink = $this->create([
'token' => $student->saudi_nid,
'status' => 'active',
'course_title' => $student->course_title,
'university_id' => $student->university_id,
'student_id' => $student->id,
'institution_id' => $student->institution_id,
'course_id' => $student->course_id,
]);
$studentContacts = $student->institutionContacts;
if ($studentContacts) {
foreach ($studentContacts as $studentContact) {
/* I get the value here, no problems */
\Debugbar::info($newLink->id);
$linkContact = $this->contacts()->create([
'type' => $studentContact->pivot->type,
'institution_contact_id' => $studentContact->pivot->institution_contact_id,
/* $newLink->id returns nothing here */
'link_id' => $newLink->id, here!!
]);
$newLink->contacts()->associate($linkContact);
$newLink->save();
}
}
$links[] = $newLink;
}
return $links;
}
The errors I receive when attempting the above code:
SQLSTATE[23000]: Integrity constraint violation: 1048
Column 'link_id' cannot be null
(SQL: insert into `link_contacts`
(`type`, `institution_contact_id`, `link_id`, `updated_at`, `created_at`)
values (1, 1, , 2015-11-24 10:26:32, 2015-11-24 10:26:32))
C:\...\vendor\laravel\framework\src\Illuminate\Database\Connection.php#631
SQLSTATE[23000]: Integrity constraint violation: 1048
Column 'link_id' cannot be null
C:\...\vendor\laravel\framework\src\Illuminate\Database\Connection.php#380
To reiterate I do get the value in Laravel Debugbar but not in the method call after it!
Edit:
In my LinkContact class link_id is in my fillable attributes:
class LinkContact extends Model
{
protected $fillable = ['type', 'link_id', 'institution_contact_id'];
// rest of the class
}
It's worth noting that:
$newLink->contacts()->associate($linkContact);
Would in this instance, run a query like:
UPDATE `link_contacts` SET `link_id` = 1 WHERE `id` = 4;
So if you're setting the link_id in the create, there's no need to run associate. If memory serves you may be able to run $newLink->contacts()->create([...]) instead of both the create() and associate().
Because of the way Eloquent works, a foreign key will always be updated/inserted from running any helper method designed to automatically insert this data but you're manually specifying the key, meaning that it's subject to $fillable so I would take a look at that, and if you don't currently have it in there, add link_id to that array.
Try
$newLink->save();
before calling
$newLink->id
The id is generated only after the data was saved in the database so there's no way of knowing it before that.
1452 Cannot add or update a child row: a foreign key constraint fails (`bpr`.`trips`, CONSTRAINT `trips_driver_user_id_foreign` FOREIGN KEY (`driver_user_id`) REFERENCES `users` (`id`) ON DELETE CASCADE)
is the error.
Adding a row, manually, through MySQL works fine. If I do it through my application - nope.
The id that I am trying to insert is correct (it exists and is an integer). I checked the foreign keys and stuff, everything looks fine. I don't know what the problem might be...
Some code:
$input = Input::all();
Trip::create([
'route_from' => $input['route_from'],
'route_to' => $input['route_to'],
... adding other stuff ...
'driver_user_id' => Auth::user()->id
]);
When I var_dump(Auth::user()->id) I do get correct int number, which is the correctly corresponding ID of the certain user.
in the Trip model:
protected $hidden = [
'id'
];
protected $fillable = [
'route_from',
'route_to',
...
'driver_user_id'
];
public function Trip()
{
return $this->belongsTo('User', 'driver_user_id', 'id');
}
in the User model:
public function Trips()
{
return $this->hasMany('Trip');
}
I have the gut feeling the attributes are guarded. Your code seems correct, however the error you receive originates from the database. Could you try it like this and see if it works:
$trip = new Trip;
$trip->unguard();
$trip->fill([
'route_from' => $input['route_from'],
'route_to' => $input['route_to'],
... adding other stuff ...
'driver_user_id' => Auth::user()->id
]);
$trip->save();
Using the create method on the model makes it difficult to debug what is happening.
I am creating a real estate website that has Listing ID's attached to each listing. I am running a script via shell in CakePHP that is parsing a csv file and should be updating any listing that already exists or inserting a new one if it does not.
The problem is that I keep getting a Duplicate entry '###' for key "PRIMARY' where ### is the Listing ID that is being provided by the CSV. This script is being run from the command line.
Here's a smaller version of what my table includes:
CREATE TABLE `listings` (
`ListingID` int(11) NOT NULL,
`AccessibilityYN` varchar(50) DEFAULT NULL COMMENT 'AccessibilityYN',
`BathsFull` int(6) DEFAULT NULL COMMENT 'BathsFull',
`BathsPartial` int(6) DEFAULT NULL COMMENT 'BathsPartial',
`BathsTotal` decimal(5,1) DEFAULT NULL COMMENT 'BathsTotal',
`Beds` int(11) DEFAULT NULL COMMENT 'Beds',
PRIMARY KEY (`ListingID`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
Here's my Listing Model (notice that I have public $primaryKey = 'ListingID';)
class Listing extends AppModel {
public $name = 'Listing';
public $primaryKey = 'ListingID';
public $belongsTo = array(
'Agent' => array(
'className' => 'Agent',
'foreignKey' => 'AgentID'
)
);
}
Here's the shell I'm running via command line:
class MyShell extends AppShell {
public $uses = array('Listing');
public function update_imported_listings() {
/***SOME CODE HERE TO GET THE $entry FROM THE CSV***/
$this->Listing->ListingID = $entry['ListingID'];
if(!$this->Listing->exists()){
$this->Listing->create();
}
if($this->Listing->save($entry)){
echo "Saved Listing";
} else {
echo "Listing Failed";
}
}
}
I understand that CakePHP usually likes id to be the field used in the database, however I have set $primaryKey = 'ListingID' in my model. I've tried setting ListingID to Auto Increment in the DB but that didn't work.
Anybody have any ideas? I'm fresh out.
Setting ListingID doesnt' do anything
This line is your problem:
$this->Listing->ListingID = $entry['ListingID'];.
Irrespective of what your actual primary key field is in database the primary key value is always specified using Model->id property. As such, change it to:
$this->Listing->id = $entry['ListingID'];
You don't need to call exists
There is not need to explicitly check if record with particular primary key values exists. Cake will automatically update and record instead of creating a new one if the data array passed to save() contains a valid primary key value which exists in db. Just ensure you call create() before saving if you are using save() in a loop.
Don't break CakePHP conventions, use 'id' field as primary key.
http://book.cakephp.org/view/24/Model-and-Database-Conventions
I was getting the same error running a cakePHP shell script, turns out the latest record's ID was at the maximum value allowed by the size of the column (whoever made the table used a medium int for the id column), so auto_increment wasn't working. Changed the column to allow for larger numbers to fix. Probably something obvious, but might help someone out there.
