DataTables Editor Event Hooks

In addition to Laravel's model events, DataTables Editor offers some pre & post event hooks.

Create Events

Create action has the following event hooks:

  • creating event hook that is fired before creating a new record.
  • created event hook that is fired after the record was created.

To use the event hook, just add the methods on your editor class.

/**
* Event hook that is fired before creating a new record.
*
* @param \Illuminate\Database\Eloquent\Model $model Empty model instance.
* @param array $data Attribute values array received from Editor.
* @return array The updated attribute values array.
*/
public function creating(Model $model, array $data)
{
// Code can change the attribute values array before saving data to the
// database.
// Can be used to initialize values on new model.
 
// Since arrays are copied when passed by value, the function must return
// the updated $data array
return $data;
}
 
/**
* Event hook that is fired after a new record is created.
*
* @param \Illuminate\Database\Eloquent\Model $model The newly created model.
* @param array $data Attribute values array received from `creating` or
* `saving` hook.
* @return \Illuminate\Database\Eloquent\Model Since version 1.8.0 it must
* return the $model.
*/
public function created(Model $model, array $data)
{
// Can be used to mutate state of newly created model that is returned to
// Editor.
 
// Prior to version 1.8.0 of Laravel DataTables Editor the hook was not
// required to return the $model.
// In version 1.8.0+ the hook must return the $model instance:
return $model;
}

Edit Events

Edit action has the following event hooks:

  • updating event hook that is fired before updating an existing record.
  • updated event hook that is fired after the record was updated.

To use the event hook, just add the methods on your editor class.

/**
* Event hook that is fired before updating an existing record.
*
* @param \Illuminate\Database\Eloquent\Model $model Model instance retrived
* retrived from database.
* @param array $data Attribute values array received from Editor.
* @return array The updated attribute values array.
*/
public function updating(Model $model, array $data) {
// Can be used to modify the attribute values received from Editor before
// applying changes to model.
 
// Since arrays are copied when passed by value, the function must return
// the updated $data array
return $data;
}
 
/**
* Event hook that is fired after the record was updated.
*
* @param \Illuminate\Database\Eloquent\Model $model Updated model instance.
* @param array $data Attribute values array received from `updating` or
* `saving` hook.
* @return \Illuminate\Database\Eloquent\Model Since version 1.8.0 it must
* return the $model.
*/
public function updated(Model $model, array $data) {
// Can be used to mutate state of updated model that is returned to Editor.
 
// Prior to version 1.8.0 of Laravel DataTables Editor the hook was not required
// to return the $model.
// In version 1.8.0+ the hook must return the $model instance:
return $model;
}

Save events

In addition to create and edit events, the following save event hooks are available:

  • saving event hook that is fired after creating and updating events, but before the model is saved to the database.
  • saved event hook that is fired after created and updated events.

To use the event hook, just add the method on your editor class:

/**
* Event hook that is fired after `creating` and `updating` hooks, but before
* the model is saved to the database.
*
* @param \Illuminate\Database\Eloquent\Model $model Empty model when creating;
* Original model when updating.
* @param array $data Attribute values array received from `creating` or
* `updating` event hook.
* @return array The updated attribute values array.
*/
public function saving(Model $model, array $data)
{
// The event hook can be used to modify the $data array that is used to
// create or update the record.
 
// Since arrays are copied when passed by value, the function must return
// the updated $data array
return $data;
}
 
/**
* Event hook that is fired after `created` and `updated` events.
*
* @param \Illuminate\Database\Eloquent\Model $model The new model when
* creating; the updated model when updating.
* @param array $data Attribute values array received from `creating`,
* `updating`, or `saving`.
* @return \Illuminate\Database\Eloquent\Model Since version 1.8.0 it must
* return the $model.
*/
public function saved(Model $model, array $data)
{
// Can be used to mutate state of updated model that is returned to Editor.
 
// Prior to version 1.8.0 of Laravel DataTables Editor the hook was not required
// to return the $model.
// In version 1.8.0+ the hook must return the $model instance:
return $model;
}

Remove Events

Remove action has the following event hooks:

  • deleting event hook that is fired before deleting a record.
  • deleted event hook that is fired after the record was deleted.

To use the event hook, just add the methods on your editor class.

/**
* Event hook that is fired before deleting an existing record.
*
* @param \Illuminate\Database\Eloquent\Model $model The original model
* retrieved from database.
* @param array $data Attribute values array received from Editor.
* @return void
*/
public function deleting(Model $model, array $data) {
// Record still exists in database. Code can be used to delete records from
// child tables that don't specify cascade deletes on the foreign key
// definition.
}
 
/**
* Event hook that is fired after deleting the record from database.
*
* @param \Illuminate\Database\Eloquent\Model $model The original model
* retrieved from database.
* @param array $data Attribute values array received from Editor.
* @return void
*/
public function deleted(Model $model, array $data) {
// Record no longer exists in database, but $model instance still contains
// data as it was before deleting. Any changes to the $model instance will
// be returned to Editor.
}

Upload Events

Upload action has the following event hooks:

  • uploaded event hook that is fired after a file was uploaded.

To use the event hook, just add the methods on your editor class.

/**
* Event hook that is fired after uploading a file.
*
* @param string $id The auto-generated file id from filesystem.
* @return string
*/
public function uploaded($id) {
// return the file id.
return $id;
}
