Helper Devise：在请求环境中找不到`Warden :: Proxy`实例

问题描述

我尝试将Devise用于我的Rails应用程序。我可以注册并登录，但是当我转到其他页面 build时，出现以下错误：

I try to use Devise for my Rails app. I can sign up and login but when I go to my other page "build" I get the following error:

这是我的控制器：

class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception

  private
  # Overwriting the sign_out redirect path method
  def after_sign_out_path_for(resource_or_scope)
    build_path
  end
end

这里有我的两个局部视图：

Here rea my two partial views:

<!-- views/devise/menu/_login_items.html.erb -->
<% if user_signed_in? %>
  <li>
  <%= link_to('Logout', destroy_user_session_path, :method => :delete) %>
  </li>
<% else %>
  <li>
  <%= link_to('Login', new_user_session_path)  %>
  </li>
<% end %>

和

<!-- views/devise/menu/_registration_items.html.erb -->
<% if user_signed_in? %>
  <li>
  <%= link_to('Edit registration', edit_user_registration_path) %>
  </li>
<% else %>
  <li>
  <%= link_to('Register', new_user_registration_path)  %>
  </li>
<% end %>

调试之后，我发现问题出在我的 show控制器的这一行： template = HomeController.render（'layouts / _template'）

After debugging, I figured out that the problem is coming from this line in my "show" controller: template = HomeController.render('layouts/_template')

感谢您的帮助。

推荐答案

基于此，您需要添加 Devise ：：在控制器规格中测试Test :: ControllerHelpers 模块。将以下内容添加到rails_helper中：

Based on this SO answer you need to include the Devise::Test::ControllerHelpers module in your controller specs. Add the following to your rails_helper:

RSpec.configure do |config|
  config.include Devise::Test::ControllerHelpers, type: :controller
end
