Working different models in the same form on Ruby on Rails

Well it’s been a heck of a week, loving somethings on rails and hating others :P
Anyway I had a problem with working with different models on a form. If you are having the same kind of issues I’ll give you some pointers:
- Railscasts (ep.73, 74, 75)
- The problem I had and the solution I found (newbie code inside :P)
- Implementings has_many relationships on RailsForum
- Rails: Presenter Pattern (thanks to André Medeiros)
- Chunky Bacon!
My notes file is so big I think I’ll never solve all those issues. *g* Anyway another pointer I can give you is to check out haml. I didn’t used it but it sure is simpler than html.
