我正在编写测试，我应该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，通过函数fill_in可以正确填充每个字段。但是当提交按钮单击服务器获取一个空对象时，我的测试结果会出现以下错误：
Failure/Error: Unable to find matching line from backtrace

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

应在提交点击时调用的服务器端方法：
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
我非常感谢任何帮助或任何建议
