Associate users with roles and permissions (Mongodb)

This package allows to save permissions and roles in a database. It is built extend from Spatie Laravel Permission

Once installed you can do stuff like this:

//adding permissions to a user
$user->givePermissionTo('edit articles');

//adding permissions via a role
$user->assignRole('writer');
$user2->assignRole('writer');

$role->givePermissionTo('edit articles');

You can test if a user has a permission with Laravel's default can-function.

$user->can('edit articles');

Install

You can install the package via composer:

$ composer require Mehrdadakbari/laravel-mongodb-permission

This service provider must be installed. And Spatie provider too.

// config/app.php
'providers' => [
    ...
    Spatie\Permission\PermissionServiceProvider::class,
    Mehrdadakbari\Mongodb\Permissions\PermissionServiceProvider::class,
];

You can publish the config-file with:

php artisan vendor:publish --provider="Spatie\Permission\PermissionServiceProvider"

This is the contents of the published config file:

// config/permission.php

return [

    |--------------------------------------------------------------------------
    */

Adjust the table_names config above for support mongodb many to many relationships (using EmbedsMany)

    'model_has_permissions' => Mehrdadakbari\Mongodb\Permissions\Models\EmbedPermission::class,
    'model_has_roles' => Mehrdadakbari\Mongodb\Permissions\Models\EmbedRole::class,
    'role_has_permissions' => Mehrdadakbari\Mongodb\Permissions\Models\EmbedPermission::class,

Usage

First add the Spatie\Permission\Traits\HasRoles-trait to your User model.

use Illuminate\Foundation\Auth\User as Authenticatable;
use Spatie\Permission\Traits\HasRoles;

class User extends Authenticatable
{
    use HasRoles;

    // ...
}

This package allows for users to be associated with roles. Permissions can be associated with roles. A Role and a Permission are regular Eloquent-models. They can have a name and can be created like this:

use Spatie\Permission\Models\Role;
use Spatie\Permission\Models\Permission;

$role = Role::create(['name' => 'writer']);
$permission = Permission::create(['name' => 'edit articles']);

The HasRoles adds eloquent relationships to your models, which can be accessed directly or used as a base query.

$permissions = $user->permissions;
$roles = $user->roles()->pluck('name'); // returns a collection

###Using permissions A permission can be given to a user:

$user->givePermissionTo('edit articles');

//you can also give multiple permission at once
$user->givePermissionTo('edit articles', 'delete articles');

//you may also pass an array
$user->givePermissionTo(['edit articles', 'delete articles']);

A permission can be revoked from a user:

$user->revokePermissionTo('edit articles');

You can test if a user has a permission:

$user->hasPermissionTo('edit articles');

Saved permissions will be registered with the Illuminate\Auth\Access\Gate-class. So you can test if a user has a permission with Laravel's default can-function.

$user->can('edit articles');

###Using roles and permissions A role can be assigned to a user:

$user->assignRole('writer');

// you can also assign multiple roles at once
$user->assignRole('writer', 'admin');
$user->assignRole(['writer', 'admin']);

A role can be removed from a user:

$user->removeRole('writer');

Roles can also be synced :

//all current roles will be removed from the user and replace by the array given
$user->syncRoles(['writer', 'admin']);

You can determine if a user has a certain role:

$user->hasRole('writer');

You can also determine if a user has any of a given list of roles:

$user->hasAnyRole(Role::all());

You can also determine if a user has all of a given list of roles:

$user->hasAllRoles(Role::all());

The assignRole, hasRole, hasAnyRole, hasAllRoles and removeRole-functions can accept a string, a Spatie\Permission\Models\Role-object or an \Illuminate\Support\Collection-object.

A permission can be given to a role:

$role->givePermissionTo('edit articles');

You can determine if a role has a certain permission:

$role->hasPermissionTo('edit articles');

A permission can be revoked from a role:

$role->revokePermissionTo('edit articles');

The givePermissionTo and revokePermissionTo-functions can accept a string or a Spatie\Permission\Models\Permission-object.

Saved permission and roles are also registered with the Illuminate\Auth\Access\Gate-class.

$user->can('edit articles');

###Using blade directives This package also adds Blade directives to verify whether the currently logged in user has all or any of a given list of roles.

@role('writer')
I'm a writer!
@else
I'm not a writer...
@endrole

@hasrole('writer')
I'm a writer!
@else
I'm not a writer...
@endhasrole

@hasanyrole(Role::all())
I have one or more of these roles!
@else
I have none of these roles...
@endhasanyrole

@hasallroles(Role::all())
I have all of these roles!
@else
I don't have all of these roles...
@endhasallroles

You can use Laravel's native @can directive to check if a user has a certain permission.

Using a middleware

The package doesn't contain a middleware to check permissions but it's very trivial to add this yourself.

$ php artisan make:middleware RoleMiddleware

This will create a RoleMiddleware for you, where you can handle your role and permissions check.

// app/Http/Middleware/RoleMiddleware.php
use Auth;

...

public function handle($request, Closure $next, $role, $permission)
{
    if (Auth::guest()) {
        return redirect($urlOfYourLoginPage);
    }

    if (! $request->user()->hasRole($role)) {
       abort(403);
    }

    if (! $request->user()->can($permission)) {
       abort(403);
    }

    return $next($request);
}

Don't forget to add the route middleware to your Kernel:

// app/Http/Kernel.php
protected $routeMiddleware = [
    ...
    'role' => \App\Http\Middleware\RoleMiddleware::class,
    ...
];

Now you can protect your routes using the middleware you just set up:

Route::group(['middleware' => ['role:admin,access_backend']], function () {
    //
});

Extending

If you need to extend or replace the existing Role or Permission models you just need to keep the following things in mind:

• Your Role model needs to implement the Spatie\Permission\Contracts\Role contract
• Your Permission model needs to implement the Spatie\Permission\Contracts\Permission contract
• You must publish the configuration with this command: php artisan vendor:publish --provider="Spatie\Permission\PermissionServiceProvider" --tag="config" and update the models.role and models.permission values
