           like_idea    /ideas/:id/like(.:format)      ideas#like         comment_idea post   /ideas/:id/comment(.:format)   ideas#comment                ideas    /ideas(.:format)               ideas#index                      post   /ideas(.:format)               ideas#create             new_idea    /ideas/new(.:format)           ideas#new            edit_idea    /ideas/:id/edit(.:format)      ideas#edit                 idea    /ideas/:id(.:format)           ideas#show                      put    /ideas/:id(.:format)           ideas#update                      delete /ideas/:id(.:format)           ideas#destroy     new_user_session    /users/sign_in(.:format)       devise/sessions#new         user_session post   /users/sign_in(.:format)       devise/sessions#create destroy_user_session    /users/sign_out(.:format)      devise/sessions#destroy        user_password post   /users/password(.:format)      devise/passwords#create    new_user_password    /users/password/new(.:format)  devise/passwords#new   edit_user_password    /users/password/edit(.:format) devise/passwords#edit                      put    /users/password(.:format)      devise/passwords#update cancel_user_registration    /users/cancel(.:format)        devise/registrations#cancel    user_registration post   /users(.:format)               devise/registrations#create new_user_registration    /users/sign_up(.:format)       devise/registrations#new edit_user_registration    /users/edit(.:format)          devise/registrations#edit                      put    /users(.:format)               devise/registrations#update                      delete /users(.:format)               devise/registrations#destroy                 root        /                              home#index 

which looks right 1 can see correct route edit_user_registration_path i'm new ruby appreciated.

it's not edit_user_registration_path problem.

if @ error message, rails looking ideas_controller in devise folder (ie "devise/ideas"). if don't have controller there, means somewhere calling incorrect path.
