I think that is all that would be needed to help. I have been struggling for some time now. This is my first post, sorry if it isn't easy to read.

Answer 1

correct_user? isn't defined anywhere.
redirect_to(root_url) unless correct_user?(#user)
Rails's syntactic sugar is going to look for a model flag correct_user or a boolean-returning function #correct_user? getter. I'm assuming that you're trying to validate that an update request from a user actually belongs to the correct user. To do this you must have current_user stored in a session, and then check the request param[:id] == current_user.id
