OK, I don't know why but it happens all the time that after posting a
problem in a forum I am able to solve the problem, nearly!!!
I think I was really on the wrong track!
Now I added the following code in my patent view:
<%params = {:watchedfamily => {:Prio_No => "666666", :title =>
"Please", :watchedmembers_attributes => [{:Pub_No => "Test1"},
{:Pub_No => "Test2"}]}} %>
<%Watchedfamily.create!(params[:watchedfamily]) %>
This is creating a new record with two nested records, exactlly what I
wanted. Only problem is now: HOW TO FIRE THIS WITH A BUTTON OR LINK???
Cheers
