Overriding Session Controller Prevents custom views being used

Pregunta
Devise (2.1) was using my custom views fine until I told it to use a custom controller. Now it ignores my custom views.
Previously everything worked fine:
Tell Devise to use custom views in /config/devise.rb
# ==> Scopes configuration
# Turn scoped views on. Before rendering "sessions/new", it will first check for
# "users/sessions/new". It's turned off by default because it's slower if you
# are using only default views.
config.scoped_views = true
Add custom view: /app/views/subscribers/session/new.html.erb
Set up routes in /config/routes.rb
devise_for :subscribers
Then I added a custom SubscriberSessionsController as /app/controllers/subscriber_session_controller.rb
class SubscriberSessionsController < Devise::SessionsController
before_filter :isInIframe
private
def isInIframe
@hide_navbar = session[:in_iframe]
end
end
And modified /config/routes.rb to tell Devise to use this new controller instead of its default:
devise_for :subscribers, :controllers => {
:sessions => "subscriber_sessions"
}
Once I restart my server, Devise now uses this controller but ignores my custom view.
Solución
As is so often the case, ten minutes after posting the question I cracked it.
The reason Devise wasn't finding the view was it was looking for it in a different folder.My replacement controller was called subscriber_sessions.rb
so devise was no longer looking in views/subscribers/sessions
but views/subscribers/subscriber_sessions
.
I solved this problem with the following:
Changed my subscriber routes to:
devise_for :subscribers, :controllers => {
:sessions => "subscribers/sessions"
}
Renamed my subscriber_sessions controller to just sessions and moved it into a subscribers folder so its new name & location are: app/controllers/subscribers/sessions_controller.rb
I also had to add a namespace to the class so the new sessions_controller.rb file looks like this"
class Subscribers::SessionsController < Devise::SessionsController
before_filter :isInIframe
private
def isInIframe
@hide_navbar = session[:in_iframe]
end
end
