undefined method `session_path'

Question

I am using Rails + Devise + OmniAuth + Google OAuth2.

My user model (user.rb) contains:

devise :registerable, :omniauthable, :omniauth_providers => [:google_oauth2] 

My routes.rb look like:

Rails.application.routes.draw do   devise_for :users, controllers: { omniauth_callbacks: 'omniauth_callbacks' }   devise_scope :user do       get 'sign_in', :to => 'devise/sessions#new', :as => :new_user_session       post 'sign_in', :to => 'devise/session#create', :as => :user_session       get 'sign_out', :to => 'devise/sessions#destroy', :as => :destroy_user_session   end    get 'services', to: 'static_pages#services'   get 'my_account', to: 'my_account#index'   get 'invite', to: 'invite#show'   get 'invite/:id', to: 'invite#show'    root 'static_pages#home' end 

When I go to /sign_in, I get an exception like:

undefined method `session_path' for #<#<Class:0x007f9b7173af28>:0x007f9b713d8da8> 

in:

~/.rvm/gems/ruby-2.1.1/gems/devise-3.2.4/app/views/devise/sessions/new.html.erb 

in line:

<%= form_for(resource, as: resource_name, url: session_path(resource_name)) do |f| %> 

If I add :database_authenticatable to user.rb it all starts working, but I want my users to be able to sign-in through Google OAuth2 only, so I don't want :database_authenticable. It looks like session_path is not available for some reason, but I am not sure why and how to make it available.

Thanks, Jen

You need to reboot the rails server. That was the solution for me.
