Rails 4 - Redirect path -

i'm trying make app in rails 4.

i'm trying follow tutorial setup devise omniauth.

i have user model , profile model. associations are:

user.rb

has_one :profile 

profile.rb

belongs_to :user 

in omniauth callbacks controller, have:

def self.provides_callback_for(provider)     class_eval %q{       def #{provider}         @user = user.find_for_oauth(env["omniauth.auth"], current_user)           if @user.persisted?           sign_in_and_redirect @user,  event: :authentication            set_flash_message(:notice, :success, kind: "#{provider}".capitalize) if is_navigational_format?         else           session["devise.#{provider}_data"] = env["omniauth.auth"]           redirect_to new_user_registration_url         end       end     }   end 

in omniauth callbacks controller, currently, when user authenticates, redirect goes root path (i'm not sure why). think has current redirect @user, not having show page (which doesnt - there no views in user views folder).

i want go user's profile show page.

i can't figure out how write path. have tried each of:

 if @user.persisted?               sign_in_and_redirect @user.profile,  event: :authentication  if @user.persisted?               sign_in_and_redirect @user.profile(profile.id),  event: :authentication  if @user.persisted?               sign_in_and_redirect @user.profile_id,  event: :authentication 

does know how make redirect path. there user , user have profile. i"m stuck on how express path profile's show page.

in applicationcontroller add

def after_sign_in_path_for(resource)   profile_path(resource.profile) # or whatever route destination want end
