Rails 4 设计：SessionsController：UnknownFormat：406 错误

Question

我正在尝试使用 Devise 登录，但登录失败并收到来自 Rails 4 的 406 Not Acceptable 消息。具体来说：

Started POST "/login.user" for 127.0.0.1 at 2015-04-03 14:37:21 -0600
Processing by Devise::SessionsController#create as
  Parameters: {"utf8"=>"✓",

               "user"=>{"email"=>"jack@example.com",
                        "password"=>"[FILTERED]",
                        "remember_me"=>"0"},
               "commit"=>"Log in"}
  User Load (0.5ms)  SELECT  "users".* FROM "users" WHERE "users"."email" =   ORDER BY "users"."id" ASC LIMIT 1  [["email", "jack@example.com"]]

   (1.7ms)  COMMIT
Completed 406 Not Acceptable in 160ms (ActiveRecord: 6.0ms)

我正在尝试调整我找到的会话控制器 here；这些是相关部分：

class Users::SessionsController < DeviseController
  prepend_before_filter :require_no_authentication, only: [:new, :create]
  prepend_before_filter :allow_params_authentication!, only: :create
  prepend_before_filter :verify_signed_out_user, only: :destroy
  prepend_before_filter only: [:create, :destroy] { request.env["devise.skip_timeout"] = true }

  # GET /resource/sign_in
  def new
    self.resource = resource_class.new(sign_in_params)
    clean_up_passwords(resource)
    yield resource if block_given?
    respond_with(resource, serialize_options(resource))
  end

  # POST /resource/sign_in
  def create
    self.resource = warden.authenticate!(auth_options)
    set_flash_message(:notice, :signed_in) if is_flashing_format?
    sign_in(resource_name, resource)
    yield resource if block_given?
    respond_with resource, location: after_sign_in_path_for(resource)
  end
end

相关路线如下：

                  Prefix Verb     URI Pattern                  Controller#Action
        new_user_session GET      /login(.:format)             devise/sessions#new
            user_session POST     /login(.:format)             devise/sessions#create
    destroy_user_session GET      /sign_out(.:format)          users/sessions#destroy

我的 sessions/new.html.erb 视图使用这种形式：

<%= form_for(resource, as: resource_name, url: user_session_path(resource_name)) do |f| %>
    <input name="authenticity_token"
           type="hidden"
           value="<%= form_authenticity_token %>"/>
    <div class="field">
      <%= f.label :email %><br />
      <%= f.email_field :email, autofocus: true %>
    </div>
    <div class="field">
      <%= f.label :password %><br />
      <%= f.password_field :password, autocomplete: "off" %>
    </div>
    <% if devise_mapping.rememberable? -%>
        <div class="field">
          <%= f.check_box :remember_me %>
          <%= f.label :remember_me %>
        </div>
    <% end -%>
    <div class="actions">
      <%= f.submit "Log in" %>
    </div>
<% end %>

注意我添加了隐藏的 authenticity_token 试图解决 406 Not Acceptable 消息（我的 application.html.erb 视图中也有 <%= csrf_meta_tags %>），并且从 POST 我可以看到它正在发送。

我的用户模型有 devise: :database_authenticatable 和 validates_presence_of :email, :password。

感谢任何提示或建议！我尝试了很多建议，也有类似的问题 here。我可以提供任何其他可能有帮助的信息。
