link-to

The view also has a small remote form which upon submission

问题 I began troubleshooting my "sudden" broken routes problem in this SO question: Devise /users/sign_in redirecting to wrong controller and with help I was able to isolate the issue to the upgrade from journey 1.0.3 to 1.0.4 that occurred when I updated to rails 3.2.7. As you know, we need to be at rails 3.2.8, to apply important security fixes, but this means I must use journey 1.0.4, which breaks my devise routes. For instance, my custom new_user_session route is welcome#welcome, but it is
