Laravel/Cashier invoices() returns empty Object
问题 I've got a problem with the cashier package from Taylor (https://github.com/laravel/cashier). When I try to get the Invoices for a User the Object that is returned is Empty. For information i've set up my cashier database columns into a membership table! And then set up the proper relationships. I can charge the User if I do something like this: $user->membership->subscription('1month')->create($token); But if I want to get the invoices like so $invoices = $user->membership->invoices(); it
