Today, We want to share with you laravel permissions.In this post we will show you Easy roles and permissions in Laravel 5|6|7, hear for laravel roles and permissions from scratch we will give you demo and example for implement.In this post, we will learn about User Authorization in Laravel 5|6|7 with Spatie Laravel-Permission with an example.
laravel permissions
There are the Following The simple About laravel 5.6 – user roles and permissions Full Information With Example and source code.
As I will cover this Post with live Working example to develop spatie/laravel-permission documentation, so the laravel 6 roles and permissions is used for this example is following below.
Laravel authorization and positions permission management
Scaffold app
composer create-project --prefer-dist laravel/laravel mask_bunch
Setup packages
composer.json
"require": {
...
"spatie/laravel-permission": "^2.1",
"laracasts/flash": "^3.0",
"laravelcollective/html": "^5.3.0"
},
config/app.php
'providers' => [
...
Spatie\Permission\PermissionServiceProvider::class,
Laracasts\Flash\FlashServiceProvider::class,
Collective\Html\HtmlServiceProvider::class,
...
],
'aliases' => [
...
'Form' => Collective\Html\FormFacade::class,
'Html' => Collective\Html\HtmlFacade::class,
]
create tables for positions and permissions.
php artisan vendor:publish --provider="Spatie\Permission\PermissionServiceProvider" --tag="migrations"
create Visitor, Position, Permission
// Create Visitor model with migration and resource controller php artisan make:model Visitor -m -c --resource // Create Position model and resource controller php artisan make:model Position -c --resource // Create Permission model and resource controller php artisan make:model Permission -c --resource
add HasPositions trait provided by the package
use Spatie\Permission\Traits\HasPositions;
class Member extends Authenticatable
{
use HasPositions;
...
database/seeds/DatabaseSeeder.php
$this->command->info('Admin granted all the permissions');
} else {
// for others by default only read access
$position->syncPermissions(Permission::where('name', 'LIKE', 'view_%')->get());
}
// create one member for each position
$this->createMember($position);
}
$this->command->info('Positions ' . $input_positions . ' added successfully');
} else {
Position::firstOrCreate(['name' => 'Member']);
$this->command->info('Added only default member position.');
}
// now lets seed some visitors for demo
factory(\App\Visitor::class, 30)->create();
$this->command->info('Some Visitors data seeded.');
$this->command->warn('All done :)');
}
/**
* Create a member with given position
*
* @param $position
*/
private function createMember($position)
{
$member = factory(Member::class)->create();
$member->assignPosition($position->name);
if( $position->name == 'Admin' ) {
$this->command->info('Here is your admin details to login:');
$this->command->warn($member->email);
$this->command->warn('Password is "secret"');
}
}
defaultPermissions in Permissions Model
public static function defaultPermissions()
{
return [
'view_members',
'add_members',
'edit_members',
'delete_members',
'view_positions',
'add_positions',
'edit_positions',
'delete_positions',
'view_visitors',
'add_visitors',
'edit_visitors',
'delete_visitors',
];
}
Now run the seeder using php artisan db:seed
MemberController.php
positions' => 'required|min:1'
]);
// Get the member
$member = Member::findOrFail($id);
// Update member
$member->fill($request->except('positions', 'permissions', 'password'));
// check for password change
if($request->get('password')) {
$member->password = bcrypt($request->get('password'));
}
// Handle the member positions
$this->syncPermissions($request, $member);
$member->save();
flash()->success('Member has been updated.');
return redirect()->route('members.index');
}
public function destroy($id)
{
if ( Auth::member()->id == $id ) {
flash()->warning('Deletion of currently logged in member is not allowed :(')->important();
return redirect()->back();
}
if( Member::findOrFail($id)->delete() ) {
flash()->success('Member has been deleted');
} else {
flash()->success('Member not deleted');
}
return redirect()->back();
}
private function syncPermissions(Request $request, $member)
{
// Get the submitted positions
$positions = $request->get('positions', []);
$permissions = $request->get('permissions', []);
// Get the positions
$positions = Position::find($positions);
// check for current position changes
if( ! $member->hasAllPositions( $positions ) ) {
// reset all direct permissions for member
$member->permissions()->sync([]);
} else {
// handle permissions
$member->syncPermissions($permissions);
}
$member->syncPositions($positions);
return $member;
}
perform CRUD operation with certain permissions for the specific use
Route::group( ['middleware' => ['auth']], function() {
Route::resource('members', 'MemberController');
Route::resource('positions', 'PositionController');
Route::resource('visitors', 'VisitorController');
});

AuthorizationException Exception Handler

Position Management

if($position->name === 'Admin') {
$position->syncPermissions(Permission::all());
return redirect()->route('positions.index');
}
$permissions = $request->get('permissions', []);
$position->syncPermissions($permissions);
flash( $position->name . ' permissions has been updated.');
} else {
flash()->error( 'Position with id '. $id .' note found.');
}
return redirect()->route('positions.index');

Permissions Management
command by running php artisan make:command AuthPermissionCommand

The auth:permission command is ready, now you can run it to add/remove permissions.If you added some permissions manually in the Database, don’t forget to run/execute php artisan cache:forget spatie.permission.cache, otherwise new permissions wont work.
