Drupal

Finding the time to really learn the tools we use can be difficult, but sometimes opportunity breaks the door down. This was the case at the Pacific Northwest Drupal Summit with Jeff Griffith's presentation Hacking Komodo for Drupal Development.

In a presentation at the September 2009 meeting of the Vancouver League of Drupaliers (Vancouver's Drupal user group) core Drupal Developer and Now Public Development Team Lead Károly "CHX" Négyesi spoke about the importance of APIs in Drupal 7. If you're serious about scalability APIs are no longer an optional convenience. For some this may not be an issue, for others this could be a mindset change. Károly also discussed some other Drupal 7 improvements like functional testing.

This is a video of his presentation.

Last week was Mozilla Service Week and local Mozilla Messaging Technical Support Lead Roland Tanglao organized a Vancouver event at the offices of Agentic. At this point many Drupalistas are probably thinking: Wait a minute, is this the same Roland who used to work at Bryght? Yes, yes it is. And Vancouver readers are probably thinking: Wait a minute, Mozilla has an office in Vancouver? Yes, yes they do.

Drupal RSS functionality is spread out, and so is information on it. After first accumulating mental notes, which turned into a collection of written notes and code snippets, I realized there's a lot to be said on the topic. A single overview covering all things RSS seemed like a useful idea. This is a starting point covering many things RSS. I invite you to leave a comment if you have anything to add, a great reference or blog post, or if I've gotten something wrong.

"Out of the box" RSS

• RSS is configured and controlled at Administration > Content management > RSS Publishing
  
  
• The default RSS URL is rss.xml (e.g. www.example.com/rss.xml)
• The default RSS feed selects content using the same selection criteria as the /node path ("/node" is the default front page setting). It contains the content of any node that's both "Published" and "Promoted to front page".
  
  
  
  The exact content and number of nodes is determined by the RSS settings.
• There is no provision to theme a node's RSS output in the PHPTemplate theme engine. Your node.tpl.php file is ignored when the feed content is rendered.
• Because of the above point, double check the RSS feed output of any feed containing nodes you've created or modified with CCK.
• Every taxonomy term automatically gets a feed (whether you want it or not)
• The is no provision in the Drupal base installation (core) to publish comments in a RSS feed. A contributed module (RSS Comments or Views) is required. More on this later on.
• The RSS feed will only be published on the front page. More on this later.

Freebase is an open database (CC-BY) of world information with a web service interface. Think Wikipedia with an API. I've been playing around Drupal/Freebase integration for a community project we have brewing, Semantic Web Community Barn Raising in Vancouver.

Putting location data on maps, especially dynamically, used to be a dream. No longer. Thanks to open standards, APIs, Internet based map web services, and many hours of work in the Open Source community, a new wave of options are available for putting location based data on maps. And Drupal is surfing this wave!

The LinksDB module provides a nice "it just works" way for implementing a classic Links page. The standout feature is its hierarchical display of the URLs. Even after Views and CCK arrived, the hierarchical display was worth staying with the module. Sadly, with a site to upgrade and no Drupal 6 version of LinksDB in sight, it was time to convert.

Note: Drush is now a better option for running Drupal scripts. Please see this article for more information: Drupal Command Line Scripts with Drush.

Most experienced Drupal developers don't give a second thought to creating blogs, but if you're just starting out an overview is usually welcome. That's just what Rick Vugteveen from ImageX Media delivered in his presentation, Building a Blog in Drupal: When, Why and How, at the February 2009 meeting of the Vancouver League of Drupaliers (Vancouver's Drupal user group).
