I'm getting a No route matches {:action=>"create", :controller=>"event_questions" and missing required keys: [:event_id]` My question form sits inside my show.hrml.erb for my event model right now. Some of the relationship stuff is from neo4j gem so it isn't standard but the issue shouldn't be related to that. From what I know, I am posting to /events/events_id/event_questions events

问题 I am using Rails 3 and Devise to create an app where users arrive to the website and are shown a homepage containing a login and a signup form. This page has its own controller ("homepage") so it's route is root :to => "homepage#index" I want to display a different homepage if the users are already logged in.
