Allow creation of relationship resource

In Nova I have two models;

Post
Tag

Both resources should be visible in the menu, however, tags are not allowed to be created. My TagPolicy has public function create() { return false; } which prevents the creation of tags from directly accessing the resource.

Now I want my Posts to have a tag, so I have added the relation to the fields. My tags show up, but the create button is hidden due to the TagPolicy previously defined.

From the docs I get the idea that it should be possible to add public function addTag to my PostPolicy in order to allow/deny the creation of a tag on my post, however, this only works if the create is allowed for tags from the TagPolicy.

Is there any way how I can bypass this logic and be able to define the policy so that I can only create a tag from the Post?

P.S. I know in the case of Post/Tags it should be Many to Many (attach, detach), but this is just an example

Mmh good question... You should be able to return true for the create method based on the current URL. It's not the best solution, but I think it's the only solution here. Nova isn't built for these complex situations most of the time. Nova works for 90% of the use cases ;)

Any, you might be able to do this

public function create()
{
    if (request()->is('admin/resources/posts/create')) {
        return true;
    }

    return false;
}

Not sure if this is the URL, but you get the idea ;)

Unfortunately the policies are pre-loaded, so this only works upon a reload of the page. So for instance, if I go the main page of nova the create will return false and stay that way until I refresh on the posts/create page.

Mmh, that is annoying. I don't know any other workaround for it at this point.
