How to change the default name of an eloquent column

Question

I am on a project that is in production, and by default when we use a foreign key in eloquent we follow the following "user_id" rule for example to store user id.

Only at the bank I’m working they put this field as "id_user" and I will always make the relationship generates a mistake saying that the field "user_id" not found. How can I make my code understand that the user_id is the id_user in my bank?

Answer 1

When you declare the relationship between the models you have the second and third parameter of the relationship function to carry out this change to that convention, for example:

public function address() {
    return $this->hasMany('user', 'foreign_key', 'local_key');
}
