Forms with nested objects

Hi,

I’m having a problem trying to create a form that can populated nested objects. In my main object, WG, I have two lists of objects: A objects, and B objects. I want to display a form where I can select an arbitrary number of A objects with checkboxes, and a single B object with radio buttons. The problem is that when I try to do a form for the WG object, I get hungup on what attributes to use in w.check_box(). I’ve added a “selected” attribute to the A and B objects and was thinking I could use that, but when I do something like:

form_for(:wg) do |w|

w.a_list.each do |a|

w.check_box(, {}, true, false)

end

end

I keep hitting nil objects and syntax errors.

Any ideas? Did I explain myself clear enough?

Thanks,

Ryan

That looks right. I searched around for field_for which appears to be a typo. I found fields_for, and an explanation of similar to what I’m trying to do here: http://railsforum.com/viewtopic.php?id=719
