How to: implement sentry 2 permissions with Laravel 4?

Question

I\'m trying to use cartalyst sentry 2 in my site being built with Laravel 4. Basically I don\'t understand how to implement permissions.

The examples I\'ve seen for

Answer 1

Basically you have to..

Create your groups

Sentry::getGroupProvider()->create([
    'name' => 'Super Administrators',
    'permissions' => [
        'system' => 1,
    ],
]);

Sentry::getGroupProvider()->create([
    'name' => 'Managers',
    'permissions' => [
        'system.products' => 1,
        'system.store' => 1,
        'system.profile' => 1,
    ],
]);

Set a group to a particular user, in this case it is setting Managers to the current logged user

Sentry::getUser()->addGroup( Sentry::getGroupProvider()->findByName('Managers') );

Check if a user has a particular access

if ( Sentry::getUser()->hasAnyAccess(['system','system.products']) )
{
    // Will be able to do a thing
}

Check if a user is Super Administrator (only this group has the 'system' access)

if ( Sentry::getUser()->hasAnyAccess(['system']) )
{
    // Will be able to do a thing
}

Get all groups from a particular user

try
{
    // Find the user using the user id
    $user = Sentry::getUserProvider()->findById(1);

    // Get the user groups
    $groups = $user->getGroups();
}
catch (Cartalyst\Sentry\Users\UserNotFoundException $e)
{
    echo 'User was not found.';
}

Answer 2

In your groups table you set the permissions using JSON.

I have the following columns:

id | name | permissions

And a row:

1 | admin | {"admin":1, "create_news": 1}

Assign a user to a group using the table users_groups

Now you can use the following example to check if a user have a given permission:

$user = Sentry::getUser();
if ($user->hasAccess('create_news')) {
    echo "You can create a news item";
}
else {
    echo "You can't create a news item";
}
