Bare with me here. I'm a little slow. So I tried the code, and I get:
You have a nil object when you didn't expect it!
The error occurred while evaluating nil.form_ui=
Is there enough smarts built-in to populate the select boxes? Or do I
need something like:
a= Author.find(:all).collect { |a| a.name }
If that kind of code is required, do I put that in the helper form
override? Any chance I can see one complete example that works? I've
been banging my head on this for a while. When I Google, I just come
across more people that have been banging there heads on this.
Thanks! Paul
