I'm developing with CakePHP 4 and try to save a nested entity.
The new data are looking like that:
$data = [
'device_status_id' => '3',
'name' => 'myDevice',
'modules' => [
[
'name' => 'Autodetect',
'module_state_id' => '1',
'module_class_id' => '12',
'module_type_id' => '4',
'ports' => [
[
'physical_port' => '1',
'port_unit_id' => '1',
'port_identity' => '201901',
'name' => 'Analog-1',
],
[
'physical_port' => '2',
'port_unit_id' => '1',
'port_identity' => '201902',
'name' => 'Analog-2',
],
],
],
]
];
The structure is looking like that: $device -> hasMany($modules) -> hasMany($ports)
The table associations with hasMany are also given and working:
e.g.
$this->hasMany('Ports', [
'foreignKey' => 'module_id',
'dependent' => true,
'cascadeCallbacks' => true,
]);
The same for device as well...
In my controller I'm doing the following:
$device = $this->Devices->newEmptyEntity();
$device->setDirty('modules', true);
$device->setDirty('ports', true); // right?
// adding more info to $device
if ($this->request->is('post')) {
$device = $this->Devices->patchEntity($device, $this->request->getData(), [
'validate' => false,
'associated' => [
'DeviceTypes',
'DeviceStatuses',
'Modules',
'Modules.ModuleStates',
'Modules.ModuleClasses',
'Modules.ModuleTypes',
'Modules.Ports',
]
]);
$this->Devices->save($device)
Now the save fails, as the validator is complaining about a missing port->id.
So what is wrong here? The modules are created in the DB, but not the associated ports:
[
'device' => [
'modules' => [
(int) 0 => [
'ports' => [
(int) 0 => [
'id' => [
'_required' => 'This field is required',
],
....
Many thanks for your hints how I can force the ports to be added to the DB.

I have three tables, Articles, Comments, and Tags.
Tags belong to both Articles and Comments.
$this->Articles->patchEntity($entity, $this->request->getData(), [
'associated' => ['Comments.Tags']
]);
with the following error:
SQLSTATE[HY000]: General error: 1364 Field 'article_id' doesn't have a default value
Please try correcting the issue for the following table aliases:
CommentsArticles
but if I save with only 'associated' => ['Comments'] it works saving the Article and Comments with join table associations, just doesn't save any Tags.
Articles table has these associations:
$this->hasMany('Tags', [
'foreignKey' => 'article_id'
]);
$this->belongsToMany('Comments', [
'foreignKey' => 'article_id',
'targetForeignKey' => 'comment_id',
'joinTable' => 'comments_articles'
]);
Comments table has these associations:
$this->hasMany('Tags', [
'foreignKey' => 'comment_id'
]);
$this->belongsToMany('Articles', [
'foreignKey' => 'comment_id',
'targetForeignKey' => 'article_id',
'joinTable' => 'comments_articles'
]);
and Tags table has these associations:
$this->belongsTo('Comments', [
'foreignKey' => 'comment_id',
'joinType' => 'INNER'
]);
$this->belongsTo('Articles', [
'foreignKey' => 'article_id',
'joinType' => 'INNER'
]);
This is the entity after patching looks like this.
object(App\Model\Entity\Article) {
'title' => 'example article name',
'users' => [
'_ids' => []
],
'comments' => [
(int) 0 => object(App\Model\Entity\Comment) {
'id' => (int) 1,
'content' => 'this is a comment',
'tags' => [
(int) 0 => object(App\Model\Entity\Tag) {
'name' => 'example tag name',
'[new]' => true,
'[accessible]' => [
'comment_id' => true,
'article_id' => true,
'comment' => true,
'article' => true
],
'[dirty]' => [
'name' => true
],
'[original]' => [],
'[virtual]' => [],
'[hasErrors]' => false,
'[errors]' => [],
'[invalid]' => [],
'[repository]' => 'Tags'
}
],
'[new]' => false,
'[accessible]' => [
'content' => true,
'tags' => true,
'articles' => true
],
'[dirty]' => [
'tags' => true
],
'[original]' => [
'tags' => [
(int) 0 => [
'name' => '0'
]
]
],
'[virtual]' => [],
'[hasErrors]' => false,
'[errors]' => [],
'[invalid]' => [],
'[repository]' => 'Comments'
}
],
'[new]' => true,
'[accessible]' => [
'title' => true,
'tags' => true,
'comments' => true,
'users' => true
],
'[dirty]' => [
'title' => true,
'users' => true,
'comments' => true
],
'[original]' => [
'users' => []
],
'[virtual]' => [],
'[hasErrors]' => false,
'[errors]' => [],
'[invalid]' => [],
'[repository]' => 'Articles'
}
CaekPHP doesn't support that, it can only populate foreign keys of direct associations / in one direction. You could for example:
prepopulate the foreign key fields (which will of course only work when the article and/or comment already exists)
manually save the tags separately using the primary keys of the article and comment records
create association classes that pass the article primary key into the options when saving the article, and uses that to populate the article_id field when saving the tag
hook into the saving process on table level to pass on the article primary key and populate the tags with it
Here's a quick and dirty example for the latter solution, which should also give you an idea on how it could work on association level:
In ArticlesTable:
public function beforeSave(
\Cake\Event\Event $event,
\Cake\Datasource\EntityInterface $entity,
\ArrayObject $options
) {
if (isset($options['Articles.id'])) {
unset($options['Articles.id']);
}
}
protected function _onSaveSuccess($entity, $options)
{
if ($options['_primary']) {
$options['Articles.id'] = $entity->get('id');
}
return parent::_onSaveSuccess($entity, $options);
}
In TagsTable:
public function beforeSave(
\Cake\Event\Event $event,
\Cake\Datasource\EntityInterface $entity,
\ArrayObject $options
) {
if (!$options['_primary'] &&
isset($options['Articles.id'])
) {
$entity->set('article_id', $options['Articles.id']);
}
}
In my db,
"email" : [
"amnop#mailinator.com",
"abc#mail.com"
],
When I print_r($model->email),
it shows
Array ( [0] => amnop#mailinator.com [1] => abc#mail.com )
In my GridView,
<?= GridView::widget([
'dataProvider' => $dataProvider,
----
'columns' => [
-----
'price',
[
'attribute' => 'email',
'value' => function($model) {
//I need help here... I prefer any foreach function
}
],
-----
]
?>
I have to display all the emails in the same column. How to do this?
Edit
I use ActiveDataprovider as I'm getting the values from my db.
Depending on what you want to achieve, you can just implode emails array:
[
'attribute' => 'email',
'value' => function($model) {
if (is_array($model->email)) {
return implode(', ', $model->email);
}
return $model->email;
}
],
assuming you an array as
$data = [
['email' => 'amnop#mailinator.com'],
['email' => 'abc#mail.com'],
...
['email' => 'youremail100#mail.com'],
];
you can use an ArrayDataProvider
$provider = new ArrayDataProvider([
'allModels' => $data,
'pagination' => [
'pageSize' => 10,
],
'sort' => [
'attributes' => [ 'email'],
],
]);
send the data provider to the as usual
so in gridview you can use ,
<?= GridView::widget([
'dataProvider' => $dataProvider,
----
'columns' => [
-----
'price',
[
'attribute' => 'email',
'value' => function($model) {
//I need help here...
}
],
-----
]
?>
you can take a look at yii2 guide https://www.yiiframework.com/doc/guide/2.0/en/output-data-providers
and doc https://www.yiiframework.com/doc/api/2.0/yii-data-arraydataprovider
I used doctrine2 in zf3, while connect multiple db caused error.
Then following is my config in global.php
return [
'doctrine' => [
'connection' => [
'orm_default' => [
'driverClass' => PDOMySqlDriver::class,
'params' => [
'host' => '127.0.0.1',
'user' => 'root',
'password' => '123456',
'dbname' => 'zf3.com',
'charset' => 'utf8',
]
],
'orm_passport' => [
'driverClass' => PDOMySqlDriver::class,
'params' => [
'host' => '127.0.0.1',
'user' => 'root',
'password' => '123456',
'dbname' => 'zf3.com.passport',
'charset' => 'utf8',
]
],
],
'entitymanager' => [
'orm_passport' => [
'connection' => 'orm_passport',
]
],
],
];
And driver config in module.config.php as following:
'doctrine' => [
'driver' => [
__NAMESPACE__ . '_driver' => [
'class' => AnnotationDriver::class,
'cache' => 'array',
'paths' => [__DIR__ . '/../src/Entity']
],
'orm_passport' => [
'drivers' => [
__NAMESPACE__ . '\Entity' => __NAMESPACE__ . '_driver'
]
]
]
],
In my IndexController.php
public function indexAction()
{
// Get recent users
$users = $this->entityManager->getRepository(Users::class)
->findBy(['status'=>Users::ACTIVE_STATUS_NO],['timeCreated'=>'DESC']);
//\Doctrine\Common\Util\Debug::dump($users);
return new ViewModel([
'users' => $users
]);
}
The error message :
The class 'Passport\Entity\Users' was not found in the chain configured namespaces Application\Entity
the following is my global.php
return [
'doctrine' => [

it works!
I have product data coming from a 3rd party service call that I then create an object from and save to my MySQL DB. My models are as follows:
'products' hasMany>> 'product_skus' hasMany>> 'product_sku_attributes'
table relationships
In my ProductsTable.php initialize() method I have:
$this->hasMany('ProductSkus', [
'foreignKey' => 'product_no',
'dependent' => true,
]);
In my ProductSkusTable.php initialize() method I have:
$this->hasMany('ProductSkuAttributes', [
'foreignKey' => 'product_sku_id',
'bindingKey' => 'id',
'propertyName' => 'product_sku_attributes',
'dependent' => true,
]);
My controller:
$products = TableRegistry::get('Products');
$entity = $products->newEntity($product_data[0]);
$products->save($entity, [
'associated' => [
'ProductSkus',
'ProductSkus.ProductSkuAttributes',
]
]);
Here's is the relevant snippet from my entity debug:
'product_skus' => [
(int) 0 => object(App\Model\Entity\ProductSkus) {
'sku' => 'BDS1401H',
'sku_price' => (float) 366.76,

'sku_img_default' => false,
'is_default' => true,
'product_sku_attributes' => [
(int) 0 => [
'product_no' => (int) 23200,

I doubled checked, and all my fields are set as accessible in my table entity classes. Also, at this point I'm only trying to save one product record for simplicity, hence $products->newEntity().
My data is saving to 'products' and 'product_skus' tables without problem, but not to 'product_sku_products'. Can anyone see what the problem is? Is it because I'm not using the same foreignKey?
Please let me know what else I can provide for clarity.
The product_sku_attributes data is not being marshalled, it's still an array of arrays, and not an array of entities, hence it's not being saved.
Just like when saving entities, creating/patching them with associated data by default only works for first level associations. Deeper nested associations require to specify them via the associated option, ie:
$entity = $products->newEntity($product_data[0], [
'associated' => [
'ProductSkus.ProductSkuAttributes'
]
]);
$products->save($entity, [
'associated' => [
'ProductSkus.ProductSkuAttributes'
]
]);

I'm having trouble saving and updating hasMany associations. It seems that Cake can't patch the entity correctly somehow.
ProductGroups Table:
$this->hasMany('ProductIdentities', [
'foreignKey' => 'product_group_id',
'saveStrategy' => 'replace'
]);
ProductIdentities Table:
$this->belongsTo('ProductGroups', [
'foreignKey' => 'product_group_id'
]);
ProductGroupsController:
// patch entity
$productGroup = $this->ProductGroups->patchEntity($productGroup, $this->request->data, [
'associated' => [
'StaffMembers' => ['onlyIds' => true],
'ProductIdentities' => ['onlyIds' => true]
]
]);
$this->request->data:
[
'group_name' => 'Creative and Performing Arts',
'active' => '1',
'product_type_id' => '2',
'staff_members' => [
'_ids' => [
(int) 0 => '103',
(int) 1 => '11',
(int) 2 => '3'
]
],
'product_identities' => [
'_ids' => [
(int) 0 => '1760',
(int) 1 => '1762',
(int) 2 => '1763',
(int) 3 => '1764'
]
]
]
edit.ctp
<?php
echo $this->Form->input('group_name',
['class' => 'form-control']);
echo $this->Form->input('active',
['class' => 'form-control']);
echo $this->Form->input('product_type_id',
['class' => 'form-control']);
echo $this->Form->input('staff_members._ids',
['options' => $staffMembers,
'class' => 'form-control height-200']);
echo $this->Form->input('product_identities._ids',

?>
If a productGroup is not associated with any productIdentities, it saves fine. However if you want to select more productIdentities or unselect some existing ones, the data won't be saved. Instead, Cake will create new records in product_identites table.
After doing a debug, I could see that Cake did not patch entity correctly. See below:
'product_identities' => [
(int) 0 => object(App\Model\Entity\ProductIdentity) {
(int) 0 => '1760',
(int) 1 => '1762',
(int) 2 => '1763',
(int) 3 => '1764',
'[new]' => true,
'[accessible]' => [
'*' => true
],
'[dirty]' => [
(int) 0 => true,
(int) 1 => true,
(int) 2 => true,
(int) 3 => true
],
'[original]' => [],
'[virtual]' => [],
'[errors]' => [],
'[invalid]' => [],
'[repository]' => 'ProductIdentities'
}
],
The onlyIds option is supposed to stop Cake from creating new records but obviously it didn't work.
And I've formatted my data into the format suggested in Cake's documentation so I'm very confused.
$data = [
'title' => 'My new article',
'body' => 'The text',
'user_id' => 1,
'comments' => [
'_ids' => [1, 2, 3, 4]
]
];

Any comments/help is appreciated.
