It never fails! If you are having a problem trying to get something to
work, post something looking for help and within 15 minutes, you'll
figure it out!
I went back and reviewed the railscast on nested forms, which used a
has_many form and answered my 3rd question = you have to have an
array.
In my new action in the Groups controller I just added:
1.times {...@group.users.build}
and changed my fields_for to:
<%= f.fields_for :users do |user_fields| %>
and everything worked! Singular - plural is something you just always
have to think of.
