CheckIfAdmin when regular users and admins inside the same table

[schel4ok]

By default you have this code inside App\Http\Middleware\CheckIfAdmin.php

    private function checkIfUserIsAdmin($user)
    {
        // return ($user->is_admin == 1);
        return true;
    }

I wonder what should happen when replace return true; with ($user->is_admin == 1);?
Because I don't see is_admin property in users table or User model.

If you replace return true; with return ($user->is_admin == 1); in your checkIfUserIsAdmin($user) method, Backpack will only allow users with an is_admin attribute set to 1 to access the admin panel. However, by default, Backpack does not add an is_admin column to your users table or the User model. This means that unless you manually add the is_admin column to your users table and ensure your User model can access it, this check will always fail (or possibly throw an error if the property doesn't exist).

The Backpack documentation specifically mentions that if you want to differentiate between admins and regular users in the same table, you should add an is_admin column yourself and then update the checkIfUserIsAdmin method accordingly:

(A) adding an is_admin column to your users table, then changing the app/Http/Middleware/CheckIfAdmin::checkIfUserIsAdmin() method to test that attribute exists, and is true;

So, to use this approach, you need to:

1. Add an is_admin column (e.g., boolean or tinyint) to your users table.
2. Make sure your User model can access this property.
3. Then, the check ($user->is_admin == 1) will work as intended.

If you do not add this column, the check will not work, and regular users will not be able to access the admin panel, possibly resulting in errors.

If you want to use a different method (like roles/permissions), you can use Backpack's PermissionManager or another package, as described in the docs. But by default, you must implement the is_admin logic yourself if you want to use that property for admin access control Backpack 6.x Installation.

Hey @schel4ok . that's just an example, you should adapt the code to your own needs. 👍

If you are using spatie permissions, most likely you want to use $user->hasRole('admin') or something similar.

Have a nice one, cheers.
