best practice how to schedule symfony2 action [closed]

Answer 1

I had very similar needs (that's why i found this old topic) while working on an application with a lot of commands to manage.

I finally made my own bundle to manage execution and queuing of mutiple symfony command (scheduled tasks stored via Doctrine).

Here is the Git repository : CommandSchedulerBundle

I hope it will help someone.

Best regards

You can use this blog in order to do what you want. You could then use cron or someother program to trigger the action.

In summary:

First of all, you need to create a symfony command that executes the functionality that you wish. For that, create a folder named "Command" in our Bundle at the same level that we have "Controller or Resources" and put a name in our class. The name has to end with "Command" or it won't work. Let's call it "MyCommand".

    <?php
    namespace Devvness\DevvnessBundle\Command;

    use Symfony\Bundle\FrameworkBundle\Command\ContainerAwareCommand;
    use Symfony\Component\Console\Input\InputArgument;
    use Symfony\Component\Console\Input\InputInterface;
    use Symfony\Component\Console\Output\OutputInterface;

    class MyCommand extends ContainerAwareCommand
    {


 protected function configure()
    {
        $this->setName('devvness:my_command')
            ->setDescription('Descripción de lo que hace el comando')
            ->addArgument('my_argument', InputArgument::OPTIONAL, 'Explicamos el significado del argumento');
    }

    protected function execute(InputInterface $input, OutputInterface $output)
    {
        $em = $this->getContainer()->get('doctrine')->getManager();
        // Hacemos lo que sea
        $output->writeln('Hola mundo');
        $em->flush();
    }
}

Then you can call it by executing on cmd or console:

php app/console devness:mycommand 

or

php app/console devness:mycommand --my_argument=valor

Then you need to scheduled the task with cron for Unix or something like that by editing the cron file

* * * * * php /root/absolute/for/symfony/project/app/console devness:mycommand --myargument=valor

It sounds you are storing your schedule of tasks in the database. No problem. For every different type of task (eg. sending newsletter, save reports) create a service, which does the task. Then add to this services a tag (like twig.extension, but your own), so you have something like a TaskChain, which knows all the tasks.

For executing create a console command, which retrieves the schedule from the database, loads the TaskChain, and executes the tasks. This console command can be simply called from a cronjob without exposing it to the web. In fact your are calling this command via the php-cli and not from a browser, the standard time limit is unlimited. No controllers should be involved for executing.

This should be all organized in an extra TaskBundle.

Try JmsJobQueue (documentation) which can handle :

• List item
• Running Symfony console commands,
• Reading Jobs from database,
• Job scheduling,
• Queue size,
• Multiple queues,
• Job dependency (chaining logic),
• Web page for real time monitoring and filtering,
• Command output in job detail (web page),
• Command statistics.
