I’ve User model which has HasMany relation with Post model. When I include a field for HasMany in User resource of Nova, I see there is Create post button. How do I remove/hide that button?
You could achieve this with Policies.
According to the documentation:
If a policy exists but is missing a method for a particular action, the user will not be allowed to perform that action. So, if you have defined a policy, don’t forget to define all of its relevant authorization methods.
So in your case, if you want to hide the button completely, just create a policy for your resource (PostPolicy) and don’t implement the create method.
Answer：
You need to 2 things here.
-
In your Post resource
public static function authorizable()
{
return true;
} -
Now create policy for Post and
return truefor all methods except create, for createreturn falseand inAuthServiceProvider.php
put
protected $policies = [
Post::class => PostPolicy::class,
];
And you are done.
Answer：
In case someone is still looking for the solution, you can authorise attaching/detaching resources in your policies:
https://nova.laravel.com/docs/2.0/resources/authorization.html#authorizing-attaching-detaching
So in this case, you have a UserPolicy to which you add a function:
attachPost(User $user, User $model, Post $post)
{
return false;
}
The $user variable is the user that is signed in, the $model variable is the user page that is viewed.
