Ruby Capybara测试：表单提交时向服务器返回了一个空数据

我正在编写测试，我应该在其中编辑用户数据并单击提交按钮。从页面的屏幕截图可以清楚地看出，每个字段中的函数fill_都被正确地填充了。但是，当单击“提交”按钮时，服务器得到一个空对象，并且我的测试结果显示以下错误：

我的测试场景是：

before  :each do
      visit '/login'
      wait_for_ajax
      fill_in 'email', with: 'admin@hostel.com'
      fill_in 'password', with: 'testtest'
      click_button 'submit'
      wait_for_ajax
      wait_url '/dashboard'
      visit '/users/1'
      wait_for_ajax
    end
    scenario 'click on submit with edition' do
                find('#name').set('EDIT')
                fill_in 'email', with: 'testtest@hostel.com'
                click_button 'パスワードを変更する'
                fill_in 'password', with: 'testtest'
                fill_in 'password-confirmation', with: 'testtest'
                click_button '保存'
                page.save_screenshot('po.png')
                expect(page).to have_current_path('/users')
    end

我将非常感谢任何帮助或建议

显示实际的HTML而不是模板，并显示该模板的完整回溯error@ThomasWalpole我编辑了我的文章，在那里你可以找到html和错误的完整回溯。是否有一个表单元素可以包装所显示的html，或者它只是JS？一半的输入没有

name

属性，所以我猜它只是JS？stacktrace显示正在调用

update\u资源

，但没有提交

id

参数-您的

测试日志

显示了什么？它是JS。我对capybara测试是新手，所以我不知道如何找到test.log它不是capybara的东西，它是rails的东西-它应该在应用程序根目录中的日志目录中-还添加创建用户、登录应用程序和访问相关页面的任何before块

def update_resource(resource, params)
      authorize! :update, User
      puts params.inspect
      resource = User.find(params[:id])
      params[:role] = Role.find(params[:role])
      if params.key? :password
        params[:password_expiry] = Time.now.to_i + 86400
        resource.update_attributes(params)
        UserMailer.send_user_info(@current_user.name, resource.email, params[:password]).deliver_later
      else
        resource.update_without_password(params)
      end
    end
