How do I load a vendor class in a task
  • bperinbperin
    I guess this is more of a general namespacing / composer issue but basically I have the AWS php sdk installed via composer. I'm trying to write a task that will list all the files in a bucket but I keep getting a class not found, this file is found in my tasks file


    use Aws\S3\S3Client;

    namespace Fuel\Tasks;

    class S3
    {

          public static function run()
          {
                
          }

          public static function list_photos()
          {
                $client = S3Client::factory(\Config::get('aws_config'));

                try {
                      $result = $client->listBuckets();

                      foreach ($result['Buckets'] as $bucket) {
                            // Each Bucket value will contain a Name and CreationDate
                            echo "{$bucket['Name']} - {$bucket['CreationDate']}\n";
                      }
                }
               
                catch (\Exception $e) {
                      \Log::debug($e->getMessage());
                }
          }

    }

    and ill get the error 

    Class 'Fuel\Tasks\S3Client' not found

    how do i tell it to load the class from the vendor directory?

    Assuming your use statement is correct, I think the problem is that "namespace" must be the first executable statement in a PHP file, and "use" most come after that?
  • HRabbitHRabbit
    One of the reasons I rarely use "use" statements these days. Just creates no way of seeing what is happening or what is being called from where (guessing it also removes further class conflicts).

    It's not much harder to call \Aws\S3\S3Client\S3Client::factory() (particularly in this case where there is only 1 reference) and this way it reads cleanly when you revisit your code later on.
  • HarroHarro
    Apart from an aid for lazy people, you can also "mis-use" the use statement to alias classes. For example you can change

    use Orm\Model;

    by

    use My\Own\ModelClass as Model;

    and you don't have to change your code.

    But I agree that for more common classnames such as "Model", it is difficult to see in your code where it comes from without the namespace prefix.

    Thanks for the replies, yeah what ended up working was putting namespace first, and I dont know how I didn't know I can just use the full class path to call the class like @hrabbit suggested. 
  • HarroHarro
    Yes, you can.

    The reason all core classes are aliased is that it makes it easy to extend them. If you use the core class directly, you bypass any extension and that can have consequences.
