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. The updating / updated events will dispatch when an existing model is modified and the save method is called. 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: It will then be accessible via a dynamic property by the same name as the relation. Eloquent will automatically load the relationship for you, and is even smart enough to know whether to call the get (for one-to-many relationships) or first (for one-to-one relationships) method. The isClean method will determine if an attribute has remained unchanged since the model was retrieved. Eloquent allows you to access your relations via dynamic properties. 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. The Laravel Bootcamp will walk you through building your first Laravel application using Eloquent. If you're new to Laravel, feel free to jump into the Laravel Bootcamp. For more information on configuring your database, check out the database configuration documentation. ![]() 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. If you want to search with multiple columns then you have to extend this macro to support multiple columns.Laravel includes Eloquent, an object-relational mapper (ORM) that makes it enjoyable to interact with your database. The following example represents, how to use it: public function index() Example 3: Laravel whereLike with multiple columns using macros You can use the LIKE MySQL keyword and % wildcard character with the where clause. Example 1: Laravel where Like Query use with Eloquent Model In laravel, using whereLike() eloquent method, you can implement laravel where like search query, laravel where like multiple columns and laravel collection with where like. You can use the LIKE MySQL keyword and % wildcard character with where clause. ![]() The LIKE a query is used in a WHERE clause to search for a specified pattern in a column. When you put the search form in your application, you need to use like query to get matched pattern.
