This property maps various points of the Eloquent model's lifecycle to your own event classes. To start listening to model events, define a $dispatchesEvents property on your Eloquent model. Event names ending with -ing are dispatched before any changes to the model are persisted, while events ending with -ed are dispatched after the changes to the model are persisted. The saving / saved events will dispatch when a model is created or updated - even if the model's attributes have not been changed. Artisan Console is the name of the command-line interface packaged with Laravel. The updating / updated events will dispatch when an existing model is modified and the save method is called.

This method also accepts an optional attribute argument: The isClean method will determine if an attribute has remained unchanged since the model was retrieved. You may pass a specific attribute name or an array of attributes to the isDirty method to determine if any of the attributes are "dirty". The isDirty method determines if any of the model's attributes have been changed since the model was retrieved. This is because the models are never actually retrieved when issuing a mass update.Įloquent provides the isDirty, isClean, and wasChanged methods to examine the internal state of your model and determine how its attributes have changed from when the model was originally retrieved. When issuing a mass update via Eloquent, the saving, saved, updating, and updated model events will not be fired for the updated models. The update method returns the number of affected rows. The update method expects an array of column and value pairs representing the columns that should be updated. You may use the make:model Artisan command to generate a new model: Models typically live in the app\Models directory and extend the Illuminate\Database\Eloquent\Model class.
