There is no need to write SQL queries at all. The process of synchronizing multiple databases running on different systems is simplified. Models allow data querying in your tables, as well as inserting new records into tables. The advantage is for models to perform common database operations without coding lengthy SQL queries. It is an architectural pattern where the model created in the Model-View-Controller (MVC) structure corresponds to a table in the database. How does Eloquent work?ĭevelopers can work in Eloquent with multiple databases efficiently using an ActiveMethod implementation. It works with custom web applications as it can cater to multiple databases and perform common database operations. Varying business requirements are addressed with faster development, as well as well-organized, reusable, maintainable and scalable code. Laravel helps make development faster and provides an adequate solution to most problems encountered. As developers need to create complex websites and other applications, they prefer a hassle-free and shorter development time. The PHP Laravel framework is packaged with the Eloquent Object Relational Mapper (ORM), which provides an extremely easy way to communicate with a database. You may do this using the $fillable property on the model.By: jmendez | SeptemWhat is Laravel Eloquent? So, to get started, you should define which model attributes you want to make mass assignable. For example, a malicious user might send an is_admin parameter through an HTTP request, which is then passed into your model's create method, allowing the user to escalate themselves to an administrator. However, before doing so, you will need to specify either a fillable or guarded attribute on the model, as all Eloquent models protect against mass-assignment by default.Ī mass-assignment vulnerability occurs when a user passes an unexpected HTTP parameter through a request, and that parameter changes a column in your database you did not expect. The inserted model instance will be returned to you from the method. You may also use the create method to save a new model in a single line. This is because the models are never actually retrieved when issuing a mass update. When issuing a mass update via Eloquent, the saved and updated model events will not be fired for the updated models. The update method expects an array of column and value pairs representing the columns that should be updated. The easiest way to create a model instance is using the make:model Artisan command: All Eloquent models extend Illuminate\Database\Eloquent\Model class. Models typically live in the app directory, but you are free to place them anywhere that can be auto-loaded according to your composer.json file. To get started, let's create an Eloquent model. For more information on configuring your database, check out the documentation. Models allow you to query for data in your tables, as well as insert new records into the table.īefore getting started, be sure to configure a database connection in config/database.php. Each database table has a corresponding "Model" which is used to interact with that table. The Eloquent ORM included with Laravel provides a beautiful, simple ActiveRecord implementation for working with your database.
