My first production Symfony application is a newletter manager and sender. This gave me a few headaches that I couldn’t easily find solutions for in the Docs. In the end trial, error and other sources came up with some gems that kept things moving.
Assigning complete module output to a variable
This is pretty useful, dropped into your Action this retrieves the fully rendered (layout, template, content) output of another Action/Module. Many of the email examples recommend putting the content you wish to send out into a partial or component and show how to grab it for variable assignment, but this will take a whole page you might want to email ‘as is’. I use it retrieve a current newsletter page as it is would be rendered for the web so I can drop it into an email.
Flexible but full Absolute URLs to assets
With this, I can provide the editor interface, management and preview options, a live copy of the current newsletter and archive of old ones on the web, and share the very same content in mails to subscribers.
