RSS and Atom feeds in Catalyst
The Catalyst cookbook provides two recommendations for adding RSS feeds to your application:
- Create an XML template, populate the stash with data, let your template view render it, then override the
Content-Type:header of your view with Catalyst::Response.
- Use an XML::* feed module to render the XML, manually set the Catalyst::Response body, then set the
The former almost makes me angry, and the latter, although saner, puts view-specific responsibilities on the shoulders of the Controller.
Catalyst::View::XML::Feed is an attempt at something cleaner, and more in the spirit of MVC, which makes the nitty-gritty details of presentation entirely the responsibility of the view. Using it is pretty much what you would expect from any view:
- Put your data in
- Forward to your View::Feed (or whatever you called your Catalyst::View::XML::Feed subclass)
It attempts to be as intelligent as possible, allowing you to supply data in a wide range of formats to the
feed value in the stash. These can be XML::* Atom or RSS objects, custom objects, plain hashrefs of values, etc.
As always, any recommendations or other feedback are warmly welcomed.
