Hi, I'm getting an error when I submit the form http://pastie.org/846712 I tried changing "f.fields_for :users do |builder|" to "f.fields_for :user do |builder|", but it generated nothing.
To give you a picture of how my accounts controller looks like: http://pastie.org/846714 And the error I'm getting is on: http://pastie.org/846715
Thanks, Emil.
