Of course, your database tables are probably related to one another. For example, a blog post may have many comments, or an order could be related to the user who placed it. Eloquent makes managing and working with these relationships easy. Laravel supports four types of relationships:

In the example above, Eloquent will look for a user_id column on the phones table. If you would like to define a different foreign key column, you may pass it as the second argument to the belongsTo method:
