When you're solving a problem in Rails, what websites do you turn to as resources? (... other than StackOverflow!) I'm not looking for links to tools such as IDEs, but rather information resources. One url per answer please to help voting. ...
Hulu, Twitter, Techcrunch, etc are written in Ruby. Yahoo, Facebook, and tons of big social networks are written in PHP. But what are some big top-name enterprise sites written in Python?

Or Is there a better way of doing this instead of using two separate forms? Is there a better way to spread a long form into multiple tabs and when I press su...
I have a VirtualHost which sets the handler for Location / to a PerlModule to deploy a catalyst application. I want to convert the catalyst application to rails, but gradually.

Here is one more newbie question: require 'tasks/rails' I saw this line in Rakefile in the root path of every rails project. I guess this line is used to require vendor/rails/railties/lib/tasks/rails.rb to get all rake tasks loaded: $VERBOSE = nil # Load Rails rakefile extensions Dir["#{File.dirname(__FILE__)}/*.rake"].each { |ext| l...

I have implemented authentication systems for webapps several times over the years, but before I do it once more, I thought I'd ask if there's a canned solution I should know about. Last time I checked, there was no built-in Rails authentication system and the standard solution was the restful-authentication plugin. Is that still the ca...

I've been a dev using rails since it's initial release and have recently lost touch with it because I've done a lot of work with Django due to my recent fondness of python. I do like Ruby as well and was asked by a friend recently if he should approach Rails or Django. Given that Rails is merging with merb and has a huge user-base versus...

The problem I have encountered is that to use the partitioning the primary key on the table must include the columns used in the partitioning function.

I have a task in capistrano wherein I want just a single line to run only if the server is a marked as primary. Is there a variable or method that I can reference inside a task?

Tomorrow, I will meet a client that is not working in technology but might ask if RubyOnRails is the right choice for his site. He might think that there's not enough RoR programmers and that he will be "hostage" of the language. I have good reasons to use RoR and the client has good reasons to like it (it costs less!). Do you have "of...
