Conditionally add and update relations

Currently I got this situation. A user can have only 1 shipping address and only 1 billing address. In Filament's admin panel's user form, admin can change user's info. However I want to set restrictions, so that admin cant give a user >1 address of type shipping, and cant give a user >1 address of type billing. That also implies that when the user already got 1 billing address, the admin can't change that user's shipping address to type=billing. How can something like that be done?

In most cases you can pass Closures or Callables to filament methods.

How exactly do you do that?

Create a policy according to the laravel docs then handle the conditions in each method based on your apps authorization. Filament defaults to Laravel’s policies to handle model authorization. https://laravel.com/docs/11.x/authorization#creating-policies

Actually, policy is only half the answer.
Normally, you create a policy, then you apply it in controller method, like

$this->authorize('action', $modelInstance);

$this->authorize('action', $modelInstance);

$this->authorize('action', $modelInstance);

$this->authorize('action', $modelInstance);
But Filament have its own controllers. It doesnt go thru any of the controllers that I wrote.
Hence in this situation, how can policy (or any type of pre-saving checks) be done upon the click of the add/delete/edit buttons?

You can add ->authorize() in your action component. In this case, you are using Repeater you can customize addAction by follow with https://filamentphp.com/docs/3.x/forms/fields/repeater

->addAction(fn($action)=> $action->authorize(...

->addAction(fn($action)=> $action->authorize(...

->addAction(fn($action)=> $action->authorize(...

->addAction(fn($action)=> $action->authorize(...
