![]() You may do this using the $fillable property on the model. 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. It is more explicit as update returns the same 0 for a non-existent user and a if the user details already where what you are trying to set it to.The Eloquent ORM included with Laravel provides a beautiful, simple ActiveRecord implementation for working with your database. So for you it might be better to first check if the user exists with either a User::findOrFail($id) or just check the return of User::find($id) and then if the user exists you do your conditional update on the returned $user. Run the same query again and you will notice it returns 0 affected rows as the name is already Testing > $retval = DB::table('users')->where('id', 1)->update() ![]() ![]() Useful side note, play with php artisan tinker, ie. So if you try to update the name and lastname of a user with the details it actually already contains the query will return 0. ![]() However, for you it might also not signify an error even if a 0 was returned as it just means that no records where updated. To get started with migrations, you need to setup Laravel migration. Assuming that our database is up and running. Also it provides a way of adding version control to your database. 0 means that no records have been updated. Migration Migration is a process of managing your database by writing PHP rather than SQL. So the above will return the number of records that where updated. An update query returns the number of rows that where affected by the update query. ![]()
