Ruby on Rails Devise Edit Registration Routing Error

Question

I'm using Ruby 2.0.0 and Rails 4.0.2. When I click the submit button on the edit profile page, I get this routing error:

Routing Error

No route matches [PATCH] "/users/sign_in"

I do not exactly understand how the devise routing works since the only relevant line in the routes.rb file I see is devise_for :users. Here are some of my files. Thank you.

/config/routes.rb

SampleApplication::Application.routes.draw do

  resources :pins

  devise_for :users

  root 'pages#home'
  get 'about' => 'pages#about'
  get 'contact' => 'pages#contact'

end

/models/user.rb

class User < ActiveRecord::Base
  devise :database_authenticatable, :registerable, #:recoverable, 
        :rememberable, :trackable, :validatable

  has_many :pins
end

/views/devise/registrations/edit.html.erb

<h2>Edit <%= resource_name.to_s.humanize %></h2>

<%= simple_form_for(resource, :as => resource_name, :url => session_path(resource_name), html:          {class: 'form-horizontal'}) do |f| %>

  <%= f.error_notification %>

  <%= f.input :password, label: "New Password", autocomplete: "off" %>
  <%= f.input :password_confirmation, label: "New Password", autocomplete: "off" %>
  <%= f.input :current_password %>

  <div class="form-actions">
    <%= f.submit "Update", class: "btn btn-primary"%>
  </div>
<% end %>

<h3>Cancel my account</h3>

<p>Unhappy? <%= link_to "Cancel my account", registration_path(resource_name), :confirm => "Are      you sure?", :method => :delete %>.</p>

<%= link_to "Back", :back %>

Your simple_form is pointing to the wrong submit url.

It says

<%= simple_form_for(resource, :as => resource_name, :url => session_path(resource_name), html:          {class: 'form-horizontal'}) do |f| %

but the url should point to the user_registration_path , not session_path , so

<%= simple_form_for(resource, :as => resource_name, :url => user_registration_path(resource_name), html:          {class: 'form-horizontal'}) do |f| %
