symfony init-batch

Posted July 13, 2008 * Comments(4)

while building a newsletter app in symfony I had to write a batch process, unfortunately there isnt enough documentation for doing that on the symfony website. However I would just get the following error:

1
2
3

unagi:htdocs rajatpandit$ symfony init-batch backend prod mailer
  [Exception]
  The specified batch "backend" does not exist.

Digging in the code, I figured out that the correct syntax is:

1
2
3

unagi:htdocs rajatpandit$ symfony init-batch default mailer backend
>> file+     /Users/rajatpandit/websites/edu/htdocs/batch/mailer.php
>> tokens    /Users/rajatpandit/websites/edu/htdocs/batch/mailer.php

where:

  • default: Default skeleton for the batch script
  • mailer: Name of the batch script that you want to create
  • frontend: Name of the application under which you want to create the batch file.

The newly created batch script is created under the folder /batch folder

    Hi!
    Thanks for this tip!

    In the symfony book, it’s written:
    ” The symfony CLI offers an init-batch task, which automatically creates a skeleton similar to the one in Listing 6-3 in the batch/ directory. Just pass it an application name, an environment name, and a batch name as arguments.”
    on the page: http://www.symfony-project.org/book/1_0/06-Inside-the-Controller-Layer#Batch Files

    Thanks to your post, I didn’t have to search the code to understand the arguments needed by the init-batch script.

    Thanks a lot!
    Dave

    Hi Rajat,

    How do I run these batch scripts?

    Can I run these from the command prompt using :
    >php batch/FileName.php

    or Should I use cron to run them ?

    Please explain.

    Thanks.

    hi Suresh,
    I suppose you can, in my current implementation i just used php code.

    $php_path = sfConfig::get(’app_php_path’);
    $script_path = SF_ROOT_DIR . DIRECTORY_SEPARATOR . ‘batch’ . DIRECTORY_SEPARATOR . ‘mailer.php’;
    $full_exec_command = $php_path .’ -q ‘ . $script_path;

    // invoke the newsletter
    exec($full_exec_command, &$output);

    you can call it via php if you need to call it once in a while or put in a cron file if you need to do it periodically, its pretty much down to you. hope that answers your question.
