Gaining application/module context from a symfony task

I have written a reporting suite, and I have a specific report that builds a CSV file. Serving this file via a browser on demand isn't an issue, but I need to be able to build this CSV file nightly, and email round a link to be able to download it.

Essentially, I need to be able to replace a specific action with a symfony task, run via cron. So how do I gain application/module context from a symfony task? And secondly, how would I invoke the SwiftMailer library from a symfony task?

I'm using symfony开发者_开发知识库 v1.4.4 and PHP v.5.2.13.

In the configure() function of your task, you need to define the application involved in your task :

$this->addOptions(array(
  new sfCommandOption('application', null, sfCommandOption::PARAMETER_REQUIRED, 'The application name','frontend'),
  new sfCommandOption('env', null, sfCommandOption::PARAMETER_REQUIRED, 'The environment', 'dev'),
  new sfCommandOption('connection', null, sfCommandOption::PARAMETER_REQUIRED, 'The connection name', 'doctrine'),
));

And then you have to create the context in the execute() function :

sfContext::createInstance($this->configuration);

Finally you can call Swift very easily :

$this->getMailer()->composeAndSend($sender,$dest, $subject, $mailBody);

Let's assume we we have --application and --env CLI task options defined in taskName::configure() method

Then receiving application context in taskName::execute() method will look like:

$context = sfContext::createInstance(ProjectConfiguration::getApplicationConfiguration($options['application'], $options['env']))
