I have 3 tables names articles,comments,addresses.
articles -> fields(id,title,body)
comments -> fields(id,article_id,comment)
addresses-> fields(id,article_id,address)
and in my articles controller i have kept dependent=>true and also cascadeCallbacks=>true. First i tried with dependent => true,i dint work then added cascade, still it does not work. Below is my code.
$this->hasMany('Comments', [
'className' => 'Comments',
'dependent' => true,
'cascadeCallbacks' => true,
]);
$this->hasOne('Addresses',[
'dependent' => true,
'cascadeCallbacks' => true,
]);
but while deleting articles, associated records are not deleted.
public function delete($id = null)
{
$this->request->allowMethod(['post', 'delete']);
$article = $this->Articles->get($id);
if ($this->Articles->delete($article)) {
$this->Flash->success(__('The article has been deleted.'));
} else {
$this->Flash->error(__('The article could not be deleted. Please, try again.'));
}
return $this->redirect(['action' => 'index']);
}
Please tell me what is the mistake i did. or any code need to be added or changed????
Pl help
Try this :
$this->hasMany('Comments', [
'foreignKey' => 'article_id',
'dependent' => true,
'cascadeCallbacks' => true
]);

I have two database with name default and default_history. And tables with name users and wafer_detail_history under default database and order_history under default_history database. want to associate Users table with OrderHistory table.
OrderHistoryTable :-
public function initialize(array $config)
{
parent::initialize($config);
$this->setTable('order_history');
$this->setDisplayField('id');
$this->setPrimaryKey('id');
$this->addBehavior('Timestamp');
$this->hasMany('WaferDetailHistory', [
'foreignKey' => 'order_id'
]);
$this->belongsTo('Users', [
'foreignKey' => 'created_by',
'joinType' => 'INNER'
]);
}
i used this.
$connection = ConnectionManager::get('default_history');
$this->OrderHistory = TableRegistry::get('OrderHistory');
$this->OrderHistory->setConnection($connection);
$id = 37;
$order_history = $this->OrderHistory->get($id, ['contain' => ['Users']]);
but not able to succeed. getting this error:
Base table or view not found: 1146 Table 'default_history.users'
doesn't exist
I had the same problem few days ago,
You must had 'strategy' => 'select' in your BelongTo to join with the other database
$this->belongsTo('Users', [
'strategy' => 'select'
'foreignKey' => 'created_by',
'joinType' => 'INNER'
]);
Try this on the OrderHistoryTable.php File:
$this->setTable('default_history.order_history');
I have an issue with the following case :
Users Table
id, profile_id, name, created, modified
Profiles Table
id, first_name, last_name, gender
Businesses table
id, name, created, modified
I have a relation table many to many to link profiles to businesses : businesses_profiles
id, business_id, profile_id, created, modified
When i try to create a new business, I would like to link directly logged in user profile id to the business I'm creating.
in my profileTable, I've added in initialize() :
$this->belongsToMany('Businesses', [
'alias' => 'Businesses',
'foreignKey' => 'profile_id',
'targetForeignKey' => 'business_id',
'joinTable' => 'businesses_profiles'
]);
in my businessesTable, I've also put in initialize() method:
$this->belongsToMany('Profiles', [
'alias' => 'Profiles',
'foreignKey' => 'business_id',
'targetForeignKey' => 'profile_id',
'joinTable' => 'businesses_profiles'
]);
In each entities Business & Profile, I put respectively in right context :
protected $_accessible = [
'*' => true,
'id' => false,
'businesses' => true,
'_joinData' => true
];
and :
protected $_accessible = [
'name' => true,
'slug' => true,
'active' => true,
'hash' => true,
'data' => true,
'approved' => true,
'created' => true,
'modified' => true,
'profiles' => true,
'_joinData' => true
];
Nothings work about saving in my businesses_profiles table.
Thanks in advance for your help,
Best,
Laurent.
Thanks a lot for your help. I've found the solution by using the link() method provided by CakePHP.
I'll share my add function here, if it can help others :
public function add()
{
$business = $this->Businesses->newEntity();
if ($this->request->is('post')) {
$business = $this->Businesses->patchEntity($business, $this->request->getData());
$business->set('hash');
$business->set('active', 0);
$business->set('slug');
$profile = TableRegistry::getTableLocator()->get('Profiles')->get($this->_currentUser->profile_id);
if ($this->Businesses->save($business)) {
**$this->Businesses->Profiles->link($business, [$profile]);**
$this->Flash->success(__('The business has been saved.'));
return $this->redirect(['action' => 'index']);
}
else
{
debug($business->getErrors()); // debug
$this->Flash->error(__('The business could not be saved. Please, try again.'));
}
}
$this->set(compact('business'));
}
Before I had this:
//ArticlesController::index
$articles = $this->Articles->find('all', [
'contain' => ['Comments']
]);
So I set the fields key:
//ArticlesController::index
$articles = $this->Articles->find('all', [
'fields' => ['title', 'text],
'contain' => ['Comments']
]);
Since I set the fields key the result of the find is not bringing the comments anymore.
$articles = $this->Articles->find('all')
->select(['fields_you_want_from_Articles'])
->contain(['Comments' => function($q) {
return $q
->select(['fields_you_want_from_Comments']);
}]);
I have a model/table solicitation with 2 fields (user_id and analyst_id) related to field id in model table user.
In my view, i have a gridview with fields:
[
'attribute' => 'user_id',
'enableSorting' => true,
'value' => function ($model) {
return $model->user->username;
},
]
How do same with analyst_id (i need show the username based another id) ?
UPDATE
Simply create another relation for analyst:
Add in model:
public function getAnalyst()
{
return $this->hasOne(User::className(), ['id' => 'analyst_id']);
}
Displaying in GridView:
[
'attribute' => 'analyst_id',
'enableSorting' => true,
'value' => function ($model) {
return $model->analyst->username;
},
],
Or if the analyst might not exist replace return part:
return $model->analyst ? $model->analyst->username : null;
I think
'value' => function ($model) {
return User::findOne($model->analyst_id)->username;
},
PS Add the correct namespace for User
I have used the gii tool to create crud application. I have 3 tables the tbl_targetcities, lib_cities, and lib_provinces. I was able to connect lib_cities to tbl_targetciteis but not the lib_provinces. And also the sorting of city / Municipality does not work. It seems that it sorts according ti the ID.
tbl_target_cities
lib_cities
lib_provinces
sample View
So far here is my relation in the model.
public function getCityName()
{
return $this->hasOne(LibCities::className(),['city_code'=>'city_code']);
}
in my view file...
<?= GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
[
'attribute'=>'city_code',
'value'=>'cityName.city_name'
],
[
'attribute'=>'prov code',
'value'=>'cityName.city_name'
],
'kc_classification',
'cluster',
'grouping',
'priority',
'launch_year',
['class' => 'yii\grid\ActionColumn'],
],
]); ?>
How to display the prov_name from lib_provinces???
EDIT to answer user2839376 question in the comment box
IN THE SEARCH MODEL CLASS
$query = TblSpBub::find();
$query->joinWith('brgyCode')->joinWith(['cityCode'])->joinWith(['cityCode.provCode']);
$covered= LibAreas::find()->where(['user_id'=>yii::$app->user->identity->id])->all();
$query->all();
$dataProvider = new ActiveDataProvider([
'query' => $query,
'sort'=> ['defaultOrder' => ['id'=>SORT_DESC]],
]);
$dataProvider->sort->attributes['city'] = [
'asc' => ['lib_Cities.city_name' => SORT_ASC],
'desc' => ['lib_Cities.city_name' => SORT_DESC],
];
$dataProvider->sort->attributes['province'] = [
'asc' => ['lib_provinces.prov_name' => SORT_ASC],
'desc' => ['lib_provinces.prov_name' => SORT_DESC],
];
In LibCities model add new relation:
public function getProvince()
{
return $this->hasOne(LibProvince::className(),['prov_code'=>'prov_code']);
}
And change getCityName relation. You should add with() for relation:
public function getCityName()
{
return $this->hasOne(LibCities::className(),['city_code'=>'city_code'])->with(['province']);
}
And in view correct your columnto this:
[
'attribute'=>'prov code',
'value'=>'cityName.province.prov_name'
],
You have to use the function relations() in models.
In tbl_target_cities model:
public function relations()
{
return array(
'city' => array(self::HAS_ONE, 'LibCities', 'city_code'),
);
}
In LibCities model :
public function relations()
{
return array(
'province' => array(self::HAS_ONE, 'LibProvinces', 'prov_code'),
'targets' => array(self::HAS_MANY, 'TargetCity', 'city_code',
);
}
This will allowed you to jump throw the LibCities model,
now you can simply acces to prov name like this :
$model->city->province->prov name;
Note : You need to have the 3 models defined.
EDIT
array(
'name' => 'province name',
'value' => $data->city->province->prov_name;
),
Done it, Heres how.
in addition to the above code (original post)
// in Model I added an additional function
public function getTaskowner()
{
return $this->hasOne(Tasks::className(), ['id' => 'task_id'])
->with(
['location','taskowner']
);
}
and in view i did this
....
'columns' => [
....
[
'class' => 'kartik\grid\DataColumn',
'value'=> 'tasks.location.taskowner.name',
.....
],
.....
and it worked
key points. used an array with the 'with->(..)' to include both then in the view added 'tasks.location.taskowner.name', to join them all
