When a new model is saved for the first time, the creating and created events will dispatch. The retrieved event will dispatch when an existing model is retrieved from the database. Want to broadcast your Eloquent events directly to your client-side application? Check out Laravel's model event broadcasting.Įloquent models dispatch several events, allowing you to hook into the following moments in a model's lifecycle: retrieved, creating, created, updating, updated, saving, saved, deleting, deleted, trashed, forceDeleting, forceDeleted, restoring, restored, and replicating. 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. To get started, let's create an Eloquent model. It's a great way to get a tour of everything the Laravel and Eloquent have to offer.

In addition to retrieving records from the database table, Eloquent models allow you to insert, update, and delete records from the table as well.īefore getting started, be sure to configure a database connection in your application's config/database.php configuration file. When using Eloquent, each database table has a corresponding "Model" that is used to interact with that table. Laravel includes Eloquent, an object-relational mapper (ORM) that makes it enjoyable to interact with your database.
