Hi,
I recently had to deal with nested form, and I found quite complex to
handle it with my situation.
I have a list of choices and want to allow the user to use some from a
predefined list, by using checkboxes.
I posted the question on Stack Overflow a few days ago, but nobody
answered yet.

As I am sure you know the 'find_by*' methods are all dynamic. They are
based on the field/column name, not on the type of object the column

not be magic enough
I think one of the things you might need is a 'timer', which will let

I have added a comment form to my article show page, but after I submit
the comment, I get the following error: Couldn't find Article without an

I think it is because the Comments controller does not know which

IMHO The biggest problem with rails is the fact that it makes working
easy and fun as long as your work can follow the MVC system. If you
try to do it your way it won't be the rails way (at least as far as I
know).
