I've followed behind the instructions for the extended devise user model w/email or username login to no avail.
I'm unable to commit actions to the forms login, and it's forcing a refresh of the page itself. I did exactly what the wiki said. Maybe you can help me solve this problem. (Or give me proper instructions for Ruby on Rails 4.)
Unpermitted parameters: login
(0.0ms) begin transaction
(0.0ms) rollback transaction
I used text_field :login instead of text_field :username......But, now I'm having trouble with the authenticity token. It begins transaction, and then it rolls back.
