Installation

This package is very easy to set up. There are only couple of steps.

Composer

Pull this package in through Composer

Service Provider

Add the package to your application service providers in config/app.php file.

Config File And Migrations

Publish the package config file and migrations to your application. Run these commands inside your terminal.

php artisan vendor:publish --provider="Marievych\Roles\RolesServiceProvider" --tag=config
php artisan vendor:publish --provider="Marievych\Roles\RolesServiceProvider" --tag=migrations

And also run migrations.

php artisan migrate

This uses the default users table which is in Laravel. You should already have the migration file for the users table available and migrated.

HasRoleAndPermission Trait And Contract

Include HasRoleAndPermission trait and also implement HasRoleAndPermission contract inside your User model.

Usage

Creating Roles

Because of Slugable trait, if you make a mistake and for example leave a space in slug parameter, it'll be replaced with a dot automatically, because of str_slug function.

Attaching, Detaching and Syncing Roles

It's really simple. You fetch a user from database and call attachRole method. There is BelongsToMany relationship between User and Role model.

Checking For Roles

You can now check if the user has required role.

You can also do this:

And of course, there is a way to check for multiple roles:

Inheritance

If you don't want the inheritance feature in you application, simply ignore the parent_id parameter when you're creating roles.

Roles that are assigned a parent_id of another role are automatically inherited when a user is assigned or inherits the parent role.

Here is an example:

You have 5 administrative groups. Admins, Store Admins, Store Inventory Managers, Blog Admins, and Blog Writers.

The Admins Role is the parent of both Store Admins Role as well as Blog Admins Role.

While the Store Admins Role is the parent to Store Inventory Managers Role.

And the Blog Admins Role is the parent to Blog Writers.

This enables the Admins Role to inherit both Store Inventory Managers Role and Blog Writers Role.

But the Store Admins Role only inherits the Store Inventory Managers Role,

And the Blog Admins Role only inherits the Blog Writers Role.

Another Example:

Here, admin inherits admin.user, admin.blog, and blog.writer.

While admin.user doesn't inherit anything, and admin.blog inherits blog.writer.

Nothing inherits development and, development doesn't inherit anything.

Creating Permissions

It's very simple thanks to Permission model.

Attaching, Detaching and Syncing Permissions

You can attach permissions to a role or directly to a specific user (and of course detach them as well).

Checking For Permissions

You can check for multiple permissions the same way as roles. You can make use of additional methods like hasOnePermission or hasAllPermissions.

Entity Check

Let's say you have an article and you want to edit it. This article belongs to a user (there is a column user_id in articles table).

This condition checks if the current user is the owner of article. If not, it will be looking inside user permissions for a row we created before.

Blade Extensions

There are four Blade extensions. Basically, it is replacement for classic if statements.

Middleware

This package comes with VerifyRoleand VerifyPermission middleware. You must add them inside your app/Http/Kernel.php file.

Now you can easily protect your routes.

It throws \Marievych\Roles\Exceptions\RoleDeniedException, \Marievych\Roles\Exceptions\PermissionDeniedException exceptions if it goes wrong.

You can catch these exceptions inside app/Exceptions/Handler.php file and do whatever you want.

Config File

You can change connection for models, slug separator, models path and there is also a handy pretend feature. Have a look at config file for more information.

More Information

For more information, please have a look at HasRoleAndPermission contract.
