Sử dụng version Semantic versioning thay vì Scheme

Job middleware

// app/Jobs/JobToBeThrottled.php

// Execute the job

public function handle() {

  // allow one job to process every 5 seconds

  Redis::throttle('key')->block(0)->allow(1)->every(5)->then(function () {

    // Handle the job

  }, function () {

    // Could not obtain lock

    return $this->release(5);

  });

}

// app/Jobs/Middleware/RateLimited.php

...

namespace App\Jobs\Middleware;

use Illuminate\Support\Facades\Redis;

class RateLimited {

  // Process the queued job.

  public function handle($job, $next) {

    Redis::throttle('key')

      ->block(0)->allow(1)->every(5)

      ->then(function () use ($job, $next) {

        // Lock obtained

        $next($job);

      }, function () use ($job) {

        // Could not obtain lock

        $job->release(5);

      });

  }

}

// app/Jobs/JobToBeThrottled.php

use App\Jobs\Middleware\RateLimited;

// get the middleware that the job will use

public function middleware() {

  return [new RateLimited];

}

public function handle() {

  // handle the job

}

Lazy collections

// This loads all eloquent models into memory at the same time

// This may be a very large number if you have thousands of posts

$posts = App\Post::all()->filter(function ($post) {

    return $post->id > 500;

});

// App/Providers/AuthServiceProvider.php

...

public function boot()

{

    $this->registerPolicies();

    // Define the gate that determines who can edit posts

    Gate::define('edit', function ($user) {

        return $user->isAdmin

          ? Response::allow()

          : Response::deny('You must be an administrator to edit posts.');

    });

}

if (Gate::allows('edit')) {

  // let the user edit

}

if (Gate::denies('edit')) {

  // let the user edit

}

// get the full authorization response returned by the gate

$response = Gate::inspect('edit');

if ($response->allowed()) {

  // Let the user edit the post

} else {

  // Display the denial message

  // 'You must be an administrator to edit posts.'

  echo $response->message();

}
