Good example of written Rails coding standards?

Question

I'm in the process of developing written code standards for a Rails app and am looking for some good examples of coding standards developed by others. Something that expands a bit on the ideas discussed in...

Does anyone have a good reference to share?

Examples:

4. STYLE: Line up hash arrows for readability
5. STYLE: put spaces around => hash arrows
6. STYLE: put spaces after ',' in method params - but none between method names and '('

(Note that I'm new to StackOverflow and not sure if this counts as a "question"...please advise if not...)

Answer 1

Here's a style guide I rather like, Ruby-focused but definitely of the "Rails generation" of Rubyists:

UPDATE. Two years later, I have found a better guide, brought to you by the copycopter project
