Question

在FactoryGirl的帮助下编写单元测试时，我需要创建一个SysNav对象并将其存储在数据库中。调用构建工作正常，但当我告诉FactoryGirl创建该对象时，我得到一个ActiveRecord :: RecordNotSaved错误。

它似乎不是验证错误或由任何after_save方法引起。

我的工厂创建了这样的对象：

      factory :sys_nav do
         name 'TestSysNav'
         sn_self_id 1
         level 4
         padding_left 70
         active true
         created_by 'UnitTest'
      end

通过rails控制台创建具有这些值的对象非常正常。

我的单元测试以这种方式调用它：

    require 'test/unit'
    require 'test_helper'

    class SysNavTest < Test::Unit::TestCase

    # Called before every test method runs.
    def setup
    # Do nothing
    end

    # Called after every test method runs.
    def teardown
      sys_nav = SysNav.find_by_name 'TestSysNav'
      sys_nav.destroy if sys_nav
    end

    def test_build
      FactoryGirl.build(:sys_nav)
    end

    def test_create
      FactoryGirl.create(:sys_nav) # <-- Error occurs here
    end 

   end

我正在使用Rails 3.2.8，factory_girl_rails 4.5.0，test-unit 3.0.7和mysql2 0.3.14。

Answer 1

就我而言，这是一个引发此错误的验证错误。用于调试

    @record = FactoryGirl.create(:sys_nav)

如果上述情况出现错误，则记录为零。所以我们能做的是

    begin
      @record = FactoryGirl.build(:sys_nav)
      @record.save!
    rescue => e
      puts @record.errors.full_messages
    end

如果是因为验证错误，它会在这里返回错误。

Answer 2

没有验证错误。我的同事为lib \ lib_global添加了一个锁，用于除开发之外的所有环境。在这里添加测试环境解决了错误。

LOCK_SYS_IDS = system_setting.lock_sys_id
    LOCK_SYS_IDS = false      if Rails.env == "development"
    LOCK_SYS_IDS = false      if Rails.env == "test"

LOCK_SYS_TABLES = system_setting.lock_sys_tables
    LOCK_SYS_TABLES = false   if Rails.env == "development"          
    LOCK_SYS_TABLES = false   if Rails.env == "test"

使用FactoryGirl创建对象时，ActiveRecord :: RecordNotSaved
