The Delete Crud Action will delete a record by the id provided in the URL.
Note
Before applying any configuration to an action it must be mapped first.
If the action has not been mapped an exception will be raised.
Test or modify if the Crud Action is enabled or not.
When a CrudAction is disabled, Crud will not handle any requests to the action, and CakePHP will raise the normal
\Cake\Error\MissingActionException exception if you haven’t implemented the action in your controller.
Warning
If you have enabled Crud and you are still receiving a MissingActionException, ensure the action is enabled and
that the controller has the \Crud\Controller\ControllerTrait implemented.
To test if an action is enabled, call the enabled method on the action.
$this->Crud->action()->enabled();
To disable an action, call the disable method on the action.
$this->Crud->action()->disable();
To enable an action, call the enable method on the action.
$this->Crud->action()->enable();
To disable or enable multiple actions at the same time, Crud Component provides helper methods.
The enable and disable method can take a string or an array, for easy mass-updating.
$this->Crud->enable('index');
$this->Crud->enable(['index', 'add']);
$this->Crud->disable('index');
$this->Crud->disable(['index', 'add']);
Note
These methods simply calls the enable and disable method in each Crud Action class, and do not provide any magic
other than mass updating.
Warning
While it’s possible to update the enabled property directly on an action using the config methods,
it’s not recommend, as important cleanup logic will not be applied if you use the config() method directly.
The 1st parameter to Table::find() - the default value is all.
To get the current configured findMethod keys call the findMethod method without any arguments.
$this->Crud->action()->findMethod();
To change the findMethod value pass a string argument to the method
$this->Crud->action()->findMethod('my_custom_finder');
Note
This setting is only relevant if you use the API listener.
Note
The API listener will always enforce success and data to be part of the _serialize
array.
This method is intended to allow you to add additional keys to your API responses with ease. An example of this is the API Query Log.
To get the current configured serialize keys call the serialize method without any arguments.
$this->Crud->action()->serialize();
To change the serialize keys, pass a string or an array as first argument.
If a string is passed, it will be cast to array automatically.
$this->Crud->action()->serialize(['my', 'extra', 'keys']);
This is a list of events emitted from the Delete Crud Action.
Please see the events documentation for a full list of generic properties and how to use the event system correctly.
Called after the Controller::beforeFilter() and before the Crud action.
It’s emitted from CrudComponent::startup() and thus is fired in the same cycle
as all Component::startup() events.
Triggered when a CrudAction is going to handle a CakePHP request.
It’s emitted from CrudComponent::beforeFilter and thus is fired in the same cycle as all Controller::beforeFilter events.
The event is emitted before calling the find method in the table.
The Crud Subject contains the following keys:
Repository (Table) which the query will be executed against.Query object from the Repository where $PrimaryKey => $IdFromRequest is already added to the conditions.This is the last place you can modify the query before it’s executed against the database.
Note
An example
Given the URL: /posts/view/10 the repository object will be an instance of PostsTable and the query
includes a WHERE condition with Posts.id = 10
After the event has emitted, the database query is executed with LIMIT 1.
If a record is found the Crud.afterFind event is emitted.
Warning
If no record is found in the database, the recordNotFound event is emitted instead of Crud.afterFind.
public function delete($id)
{
$this->Crud->on('beforeFind', function(\Cake\Event\Event $event) {
$event->getSubject()->query->where(['author' => $this->Auth->user('id')]);
});
return $this->Crud->execute();
}
After the query has been executed, and a record has been found this event is emitted.
The Crud Subject contains two keys:
id The ID that was originally passed to the action and is usually the primary key of your model.entity The record that was found in the database.Note
If an entity is not found, the RecordNotFound event is emitted instead.
public function delete($id)
{
$this->Crud->on('afterFind', function(\Cake\Event\Event $event) {
$this->log("Found item: " . $event->getSubject()->entity->id . " in the database");
});
return $this->Crud->execute();
}
Note
This event will throw an exception.
The default configuration will thrown an Cake\Error\NotFoundException which will yield a 404 response.
The event is triggered after a find did not find any records in the database.
You can modify the exception class thrown using CrudComponent::message method
This event is emitted before calling Table::delete.
The Crud Subject contains the following keys:
Entity from the find() call.To abort a delete() simply stop the event by calling
$event->stopPropagation().
public function delete($id)
{
$this->Crud->on('beforeDelete', function(\Cake\Event\Event $event) {
// Stop the delete event, the entity will not be deleted
if ($event->getSubject()->item->author !== 'admin') {
$event->stopPropagation();
}
});
return $this->Crud->execute();
}
This event is emitted after Table::delete() has been called.
The Crud Subject contains two keys:
true the delete() call succeeded, false otherwisepublic function delete($id)
{
$this->Crud->on('afterDelete', function(\Cake\Event\Event $event) {
if (!$event->getSubject()->success) {
$this->log("Delete failed for entity " . $event->getSubject()->id);
}
});
return $this->Crud->execute();
}
Simple and event driven wrapper for Controller::redirect().
The Crud Subject contains the following keys:
Controller::redirect().Controller::redirect().Controller::redirect().Entity from the previously emitted event.All keys can be modified as you see fit, at the end of the event cycle they will be passed
directly to Controller::redirect().
The redirect $url can be changed on the fly either by posting a redirect_url field from your
form or by providing a redirect_url HTTP query key.
The default for most redirects are simply to return to the index() action.
