Composer Package Installation

To install Identify, make sure "regulus/identify" has been added to Laravel 5's composer.json file.

"require": {
	"regulus/identify": "1.0.*"
},

Then run php composer.phar update from the command line. Composer will install the Identify package.

Installation

Register service provider and set up alias:

Add this to the providers array in config/app.php:

Regulus\Identify\IdentifyServiceProvider::class,

And add this to the aliases array:

'Auth' => Regulus\Identify\Facade::class,

Add middleware to the routeMiddleware array in app/Http/Kernal.php:

'auth.permissions' => \Regulus\Identify\Middleware\Authorize::class,
'auth.token'       => \Regulus\Identify\Middleware\AuthenticateByToken::class,

Add and run the install command:

Add the following to the commands array in app/Console/Kernel.php:

\Regulus\Identify\Commands\Install::class,
\Regulus\Identify\Commands\CreateUser::class,

Then run the following command:

php artisan identify:install

Identify will now be installed. This includes all necessary DB migrations, DB seeding, and config publishing. The config file that is published is auth.php and will overwrite Laravel 5's default auth configuration. The default table names are prefixed with auth_, but you may alter the tables prefix by adding a --tables-prefix option to the install line:

php artisan identify:install --tables-prefix=none

php artisan identify:install --tables-prefix=identify

The former example will remove the prefix from all of the table names, so you will get users, roles, etc. The latter example will change the default table prefix of auth to identify so your table names will be identify_users, identify_roles, etc.

You should now have 4 users, Admin, TestUser, TestUser2, and TestUser3. All of the default passwords are simply password and the usernames are case insensitive, so you may simply type admin and password to log in. The 3 initial roles are Administrator, Moderator, and Member. Admin has the Administrator role, TestUser has the Moderator role, and the final 2 users have the Member role.

You may now skip ahead to the Basic Usage section.

Basic Usage

Checking whether a user is logged in:

if (Auth::check())
{
	// the user is logged in
}

Checking whether a user has a particular role:

if (Auth::is('admin'))
{
	// the user has an "admin" role
}

if (Auth::is(['admin', 'user']))
{
	// the user has an "admin" and/or "user" role
}

if (Auth::hasRole(['admin', 'user']))
{
	// the user has an "admin" and/or "user" role (hasRole() is an alias of the is() method)
}

if (Auth::isAll(['admin', 'user']))
{
	// the user has an "admin" and "user" role
}

Checking whether a user does not have a particular role:

if (Auth::isNot('admin'))
{
	// the user lacks an "admin" role
}

if (Auth::isNot(['admin', 'user']))
{
	// the user lacks the "admin" and "user" roles
}

Checking whether a user has a particular permission:

if (Auth::can('manage-posts'))
{
	// the user has a "manage-posts" permission
}

if (Auth::can(['manage-posts', 'manage-users']))
{
	// the user has a "manage-posts" and/or "manage-users" permission
}

if (Auth::hasPermission(['manage-posts', 'manage-users']))
{
	// the user has a "manage-posts" and/or "manage-users" permission (hasPermission() is an alias of the has() method)
}

if (Auth::hasPermissions(['manage-posts', 'manage-users']))
{
	// the user has a "manage-posts" and "manage-users" permission
}

Note: Permissions can be hierarchical, so a "manage" permission may contain "manage-posts", "manage-users", etc. In this case, Auth::can('manage-posts') will be satisfied if the user has the parent "manage" permission. Users may have permissions directly applied to their user accounts or indirectly via roles. Roles may have a set of permissions associated with them that users will inherit.

Adding or removing permissions:

$user = Auth::user();

$user->addPermission('manage-posts'); // add "manage-posts" permission

$user->addPermission(1); // add permission with ID of 1

$user->removePermission('manage-posts'); // remove "manage-posts" permission

$user->removePermission(1); // remove permission with ID of 1

// adding or removing multiple permissions

$user->addPermissions(['manage-posts', 'manage-users']);

$user->removePermissions(['manage-posts', 'manage-users']);

Note: These methods are necessary because there is an auth_user_permissions_cached table that is updated when permissions are updated to reduce the number of necessary permissions-related database queries.

Authorize a specific role or roles:

// redirect to "home" URI if the user does not have one of the specified roles
Auth::authorizeByRole(['admin', 'user'], 'home');

// with a custom message (otherwise a default one is provided)
Auth::authorizeByRole(['admin', 'user'], 'home', 'You are not authorized to access the requested page.');

Authorize a specific permission or permissions:

// redirect to "home" URI if the user does not have one of the specified roles
Auth::authorize(['manage-posts', 'manage-users'], 'home');

// with a custom message (otherwise a default one is provided)
Auth::authorize(['manage-posts', 'manage-users'], 'home', 'You are not authorized to access the requested page.');

Automatically redirect to a URI with the unauthorized message:

// redirect to "home" URI if the user does not have one of the specified roles
return Auth::unauthorized('home');

// with a custom message (otherwise a default one is provided)
return Auth::unauthorized('home', 'You are not authorized to access the requested page.');

The third argument is the name of the session variable. The default is 'messages' so if the user is redirected, Session::get('messages') will return an array like:

['error' => 'You are not authorized to access the requested page.']

Querying users based on a specific role or roles:

$users = User::onlyRoles('admin')->get(); // get users that have "admin" role

$users = User::onlyRoles(['admin', 'mod'])->get(); // get users that have "admin" or "mod" role

$users = User::exceptRoles('admin')->get(); // get users that do not have "admin" role

$users = User::exceptRoles(['admin', 'mod'])->get(); // get users that do not have "admin" or "mod" role

Note: The exceptRoles() scope will still return users that have another role that isn't in the array.

Route Permissions

Check whether a user has route access based on route permissions:

if (Auth::hasRouteAccess('pages.edit'))
{
	// user has access to "pages.edit" route
}

Note: This and the hasAccess() require you to set up route permissions in config/auth_routes.php.

Check whether a user has access to a URI based on route permissions:

if (Auth::hasAccess('pages/edit/home'))
{
	// user has access to "pages/edit/home" URI (based on "config/auth_routes.php" route permissions mapping)
}

To use hasRouteAccess() and hasAccess(), you may set up config/auth_routes.php to include the routes you would like to set permissions on:

return [

	'admin.*'          => ['manage'],                                // user must have "manage" permission
	'admin.pages.*'    => ['manage-pages', 'demo'],                  // user must have "manage-pages" or "demo" permission
	'admin.forms.*'    => ['manage-pages', 'manage-forms', '[ALL]'], // user must have "manage-pages" and "manage-forms" permission
	'admin.forms.view' => ['view-forms'],                            // the most specifically defined route will always be checked

];

Creating Accounts and Sending Emails

Create a new user account:

Auth::createUser();

// use custom input array
Auth::createUser([
	'name'        => 'TestUser',
	'email'       => 'test@localhost',
	'password'    => 'password',
	'role_id'     => 2,
	'permissions' => ['manage-pages', 'manage-users'],
]);

// automatically activate user account
Auth::createUser($input, true);

// suppress confirmation email
Auth::createUser($input, true, false);

Create a new user account via the command line interface:

// use default password of "password"
php artisan user:create username email@address.com

// use alternate password
php artisan user:create username email@address.com --password=anotherpassword

// automatically activate user
php artisan user:create username email@address.com --activate

// automatically activate user and suppress confirmation email
php artisan user:create username email@address.com --activate --suppress

Send an email to a user with a specific view in views/emails:

Auth::sendEmail($user, 'confirmation');

Auth::sendEmail($user, 'banned');

Auth::sendEmail($user, 'deleted');

Auth::sendEmail($user, 'password');

Activate a user account by ID and activation token:

if (Auth::activate(1, 'wHHhONhavZps1J9p8Rs6WIXsTK30tFhl'))
{
	// user ID #1 has been activated
}
