Change default primary key in Eloquent

Question

Can I change Eloquent model primary key.

I want to set primary key for example admin_id instead of \'id\'?

I know I can change table name for m

Answer 1

If you are wanting to use a composite key (a string)

You need to make sure you set public $incrementing = false otherwise laravel will cast the field to an Integer, giving 0

class User extends Model {

    protected $primaryKey = 'my_string_key';
    public $incrementing = false;

}
