associate laravel
When updating a belongsTo relationship, you may use the associate method. This method will set the foreign key on the child model: $account = App\Account::find(10); $user->account()->associate($account); $user->save(); When removing a belongsTo relationship, you may use the dissociate method. This method will set the relationship foreign key to null: $user->account()->dissociate(); $user->save();
