Building Social Features in Ruby on Rails, ActionView::Template::Error: undefined method `sessions_path'

I discovered this error when running rake test, in the adding state, test factories video, but from what I can tell it doesn't seem to be related to that, so it could have been in my code for some time now.

The error message I get is

1) Error:
test_that_/login_route_opens_the_login_page(CustomRoutesTest):ActionView::Template::Error: undefined method `sessions_path' for #<#<Class:0x000001016342a8>:0x00000104760598>

and the code from new.html.erb

<div class="row">
<div class="span4">
    <%= simple_form_for(resource, :as => resource_name, :url => session_path(resource_name), html: {class: "well"}) do |f| %>

    <fieldset>
        <legend>Sign In</legend>
        <%= f.input :email %>
        <%= f.input :password %>

        <% if devise_mapping.rememberable? -%>
            <div><%= f.input :remember_me, as: :boolean %></div>
        <% end -%>

        <div><%= f.button :submit, "Sign in" %></div>
    </fieldset>
    <% end %>

    <%= render "devise/shared/links" %>
</div>

<div class="span8">
    <h2>Signing in is easy and secure</h2>
</div>
</div>

I'm not sure what other code is relevant to this, but I will gladly copy and paste it on request Many Thanks.

Hm. I don't see anything wrong with this particular file, it looks like mine. My guess is that there's an issue in your routes.rb file (or maybe routes_test?)

Thank you for the reply, my routes.rb file looks like this:

Treebook::Application.routes.draw do
  get "profiles/show"



  as :user do 
    get '/register', to: 'devise/registrations#new', as: :register
    get '/login', to: 'devise/sessions#new', as: :login
    get '/logout', to: 'devise/sessions#destroy', as: :logout
  end

  devise_for :users, skip: [:sessions]

  as :user do
    get "/login" => 'devise/sessions#new', as: :new_user_session
    post "/login" => 'devise/sessions#create', as: :new_user_session
    delete "/logout" => 'devise/sessions#destroy', as: :destroy_user_session
  end


  resources :user_friendships

  resources :statuses
  get 'feed', to: 'statuses#index', as: :feed

  root to: 'statuses#index'

  get '/:id', to: 'profiles#show', as: 'profile'
end

and custom_routes_test.rb:

require 'test_helper'

class CustomRoutesTest < ActionDispatch::IntegrationTest
  test "that /login route opens the login page" do
get '/login'
assert_response :success
  end

  test "that /logout route opens the logout page" do
get '/logout'
assert_response :redirect
assert_redirected_to '/'
  end

  test "that /register route opens the sign up page" do
get '/register'
    assert_response :success
  end

  test "that a profile page works" do
    get '/jasonseifer'
    assert_response :success
  end

end

again thanks for the any and all help

change this line: post "/login" => 'devise/sessions#create', as: :new_user_session

TO

post "/login" => 'devise/sessions#create', as: :user_session

I did the same mistake - you should call :user_session NOT :new_user_session in the post method for login
