When working in interactive python, I tend to rely on the builtin help() function to tell me what something expects and/or returns, and print out any documentation that might help me.

What I want to do is return all articles...

I'm a web developer proficient in HTML, CSS and Javascript, but to be able to develop my own web applications, I'd like to learn a programming language besides PHP. I've been learning Python for a while now but it seems a general purpose language, a bit complex, and not suited for web-development I guess. So if my focus is creating we...

It feels like I should be able to coerce composed_of into doing what I want, but I can't figure out how. Can anyone enlighten me, or suggest a b...

In one of my templates I want to take a closer look at the controller object using the debug() helper. It is said to produce YAML suitable for HTML output. Running <%= debug(controller) %> does, however, not produce anything I call readable. It begins with: #<ClubsController:0x104467378 @_request=#<ActionController::Request:0x1044676...
