在测试环境下难以调试

Question

难以在测试环境下调试

这是我第一次在测试环境

中运行

获取错误

undefined method `[]' for nil:NilClass

这个bug有点麻烦，

因为它不会给我任何其他信息

控制器

  def index
    binding.pry
    @tool_cvt_firmware_ui_tests = Tool::Cvt::FirmwareUiTest.all
  end

  def create
    @tool_cvt_firmware_ui_test = Tool::Cvt::FirmwareUiTest.new(tool_cvt_firmware_ui_test_params)
    binding.pry    

    respond_to do |format|
      if @tool_cvt_firmware_ui_test.save
        binding.pry
    end
 end   

路由

  localized do
    namespace :tool do
      namespace :cvt do
        resources :firmware_ui_tests
      end
    end    
  end

关注档案

require 'active_support/concern'
module RemoteFwUiServer
  include ActiveSupport::Concern
  attr_accessor :params   

Answer 1

错误就是这一行attr_accessor :params

我删除后就可以了。

但是错误日志是如此模糊
