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

I have the same problem, but I am not using OmniAuth either Google OAuth2. Did you solve it at the end? — Moh, Jun 26 '15 at 10:38

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

Yes. I added a registrations_controller.rb file and forgot to reboot. Lesson: the file structure is like an initializer in development mode. – Jerome Aug 31 '16 at 10:59

Useful answer. Saved more time than Geico saves on insurance. – GavinBelson Mar 02 '18 at 18:09

I do believe that, as you use devise_scope for the sessions paths, you need to add skip to your devise_for call, like so:

devise_for :users, skip: [:sessions], controllers: { omniauth_callbacks: 'omniauth_callbacks' }

Doing so will not generate the route helpers for the sessions controller

If you add or modify anything in the devise configuration, you need to reboot the rails server. just stop and run the rails server command again
