Hi there,
I am totally new to Rails, so please forgive me that probably dumb
question, but I am stuck with the constellation of having a user and a
user_profile model.
The idea behind this is to have a user with only the user_id that
has_many user_profiles and only the newest user_profile is active.
This way I can keep track of all user data changes. But it also
requires me to create a new user and a new user_profile in one step.
So… do you know a good starting point for doing this? I have set up
the relationships and tried to work with
<% u.fields_for :user_profile do |p| %>
// profile fields here
<% end %>
nested into the user’s default creation form, but I do not know how to
save it in my action (do I have to add something to my model too?).
So please, any help is welcome and I assure to ask better questions
next time, lol 
Thanks in advance
Arne
