This is the key on the pivot table which identifies the relationship to the project. Finally, we select the related foreign key. The third parameter is the key on the pivot table that holds the key of the model we are relating. So, we use our pivot table which is users_projects. The second parameter is the table the relationship takes place on.
The first parameter is the model you are relating to. When setting up many-to-many relationships with Eloquent, there are 4 parameters you need to set. First, let’s open our User model and add the projects relationship: belongsToMany('App\Models\Project', 'users_projects', 'user_id', 'project_id') With Eloquent you have to use the belongsToMany() relationship on both the User and the Project. Defining our Relationshipsīefore we move into all of the methods regarding many-to-many relationships, we have to define the relationship on each of our models. Now that we have our tables constructed, let’s define our relationships in the App\Models\User.php and App\Models\Project.php Eloquent models respectively. This way we can only directly set this value if needed and don’t accidentally create users with admin permissions. When creating the table, I always set the default permission column to be member.

Let’s set this up.įirst we will create 3 tables within our Laravel Install.
These will be stored in the pivot table along with the relationship with the project. On each project and organization, the user has permissions. For this example, every user can belong to multiple projects and multiple organizations. That’s managing user permissions on projects and organizations. Set up a Many-To-Many Relationship with Laravel Eloquentįor this example, we are going to use a real life situation we came across when building Bugflow. I’ve tended to use a lot of these to set up Gates & Policies and other permission structures in Laravel. However, I was always slightly confused when creating and updating related data so I wrote this tutorial as a guide for myself and for you. There are a lot of other basic and useful methods available for defining and querying these relationships. In this tutorial we’ll go through a few of my favorite methods when updating and creating many-to-many relationships with Laravel Eloquent.
