No, but I do not use an IDE to write Rails code. I can think of a few cases where Rails architecture would be relatively difficult for IDEs: ActiveRecord callbacks, and of course metaprogramming and magic methods like "find_by_x". In most cases this sounds like a mismatch between IDE and framework, but the "method_missing" chain could be a unique challenge. I avoid using that construct in application code, and just accept that some of it exists in the framework -- but that it's almost certainly not the cause of any problem I'm debugging.
