Laravel blade @can policy - string

Question

I am using Laravel 5.2. So I\'m learning about how to deal with roles and permissions Authorization. Everything runs fine. I even made my own policy PostPolicy.

And now

Answer 1

You probably haven't read docs carefully enough. You should pass as the 2nd argument a model, not a string or user object. In your case, you should probably use something like this:

@section('content')
<!-- begin -->
@can('hasRole', $post)
    <h1>Displaying Admin content</h1>
@endcan

@can('hasRole', $post)
    <h1>Displaying moderator content</h1>
@endcan

@can('hasRole', $post)
    <h1>Displaying guest content</h1>
@endcan

But the question is what you really want achieve. If you want to use user roles only to verify permissions, you don't need to use this directive.

You can add to your User model functions to verify current roles for example

public function hasRole($roleName) 
{
   return $this->role == $roleName; // sample implementation only
}

and now you can use in your blade:

@section('content')
<!-- begin -->

@if (auth()->check())    
    @if (auth()->user()->hasRole('admin'))
        <h1>Displaying Admin content</h1>       
    @elseif (auth()->user()->hasRole('moderator'))
        <h1>Displaying moderator content</h1>
    @endif    
@else
    <h1>Displaying guest content</h1>
@endif
