I'm a PHP developer who knows a little bit of Ruby. I want to learn Ruby on Rails, but most of the resources I've come across treat RoR functionality as "magic" -- i.e., it has a certain internal consistency, but don't bother asking how it works in terms of Ruby, MySQL, etc. Anyway, I want a deep understanding of how RoR works, the desi...

Hopefully I haven't misunderstood the meaning of "duck typing", but from what I've read, it means that I should write code based on how an object responds to methods rather than what type/class it is. Here's the code: def convert_hash(hash) if hash.keys.all? { |k| k.is_a?(Integer) } return hash elsif hash.keys.all? { |k| k.is_a...

I have a namespaced controller for some admin functionality. My create form does not work -- it ends up routing the request to the index action instead of the create action.

In the dropdown, I'd like to display the show name. :show.name doesn't work to display the name. How do I do this...
