Question

How can I properly switch the newly installed Symfony 1.4 framework from Doctrine (that it is configured for by default) to Propel?

Answer 1

If you create new (fresh) project…

symfony generate:project xxx --orm=Propel

The easiest thing 🙂

If you want to change existing project – you have to dig in configuration file and enable propel plugin.

Your configuration file should look similar to:

// config/ProjectConfiguration.class.php
public function setup()
{
  $this->enablePlugins('sfPropelPlugin');
  ...
}

(based on Symfony page, you should dig it next time – especially Practical Symfony)
