ruby-on-rails - 在 RSpec 中获取 'Bad value for range'

这是我的代码:#app/models/user.rbclassUser:modeldolet(:user){FactoryGirl.create:user}it"shouldreturnthecorrectdisplayname"doexpect(user.display_name).toeql("Chuck")endend#spec/factories/users.rbFactoryGirl.definedofactory:userdoprovider"MyString"uid"MyString"name"ChuckNorris"oauth_token"MyString"oauth_

ruby-on-rails - Rails 3 如何允许在没有_attributes 指定的情况下传递嵌套属性

当使用accepts_nested_attributes_for时,我不想传递“child_attributes”,而是传递“child”。我很确定,如果我在我的Controller中放入大量逻辑来创建记录和子项,我就可以完成此操作。但是,为了使我的Controller保持干净和逻辑应有的位置,即本例中的模型,我想知道如何在执行POST或PUT时切换rails3以使用此语法。{"name":"test","child_attributes":[{"id":1,"name":"test_child_update"},{"name":"test_child_create"}}相当{"nam

ruby : how to prevent modification of an array instance variable through an attribute reader

抱歉这个菜鸟问题...假设我们有:classTestMeattr_reader:arraydefinitialize@array=(1..10).to_aend结束然后可以这样做:>>a=TestMe.new=>#>>a.array.map!&:to_s=>["1","2","3","4","5","6","7","8","9","10"]>>a.array=>["1","2","3","4","5","6","7","8","9","10"]这显然不利于封装,不是吗?有什么方法可以快速保护数组变量不被更改吗?...或者每当我的实例变量具有“破坏性”方法时,我是否需要实现一个深拷贝读取

ruby-on-rails - 事件管理员 :select drop-down defaults to current value in development but defaults to blank in production

我有以下ActiveAdmin表单:formdo|f|f.inputs"TimesheetDetails"dof.input:jobs_assigned_worker,:label=>"Worker",as::select,collection:Worker.allf.input:worked_time_hours,:label=>"WorkedTime(Hours)"f.input:worked_time_mins,:label=>"WorkedTime(Minutes)"f.input:driving_time_hours,:label=>"DrivingTime(Hours)"f

ruby-on-rails - rails 4 : Forcing specific values with "strong parameters"

我正在努力使用用于创建“项目”的表单。最后,我只想允许当前的user_id,但我还没有构建用户模型或身份验证,因此作为占位符,我只是硬编码1。app/views/projects/new.html.erb:{:action=>'create'})do|f|%>1})%>app/controllers/projects_controller.rbdefcreate#saveobjectifProject.create(project_params)redirect_to(:action=>'show')elserender('new')endendprivatedefproject_pa

ruby-on-rails - rails/ ruby : TimeWithZone comparison inexplicably failing for equivalent values

我在当前项目中比较DateTime时遇到了一段糟糕的时光(没有双关语意),特别是比较ActiveSupport::TimeWithZone的两个实例。问题是我的两个TimeWithZone实例具有相同的值,但所有比较都表明它们不同。执行调试时暂停(使用RubyMine),可以看到如下信息:timestamp={ActiveSupport::TimeWithZone}2014-08-0110:33:36UTCstarted_at={ActiveSupport::TimeWithZone}2014-08-0110:33:36UTCtimestamp.inspect="Fri,01Aug20

ruby-on-rails - Rails 4 强参数 : can I 'exclude' /blacklist attributes instead of permit/whitelist?

我正在将Rails3应用程序迁移到Rails4,并且正在将attr_accessible属性转换为Controller中的强参数。APIDocumentation显示如何“允许”属性:defperson_paramsparams.require(:person).permit(:name,:age)end然而,我的绝大多数属性都是批量分配安全的。我只需要将:account_id和:is_admin等几个属性列入黑名单。是否可以将属性列入黑名单而不是将几乎所有属性列入白名单?例如:defuser_paramsparams.require(:user).exclude(:account_i

ruby-on-rails - 为什么 PG::UniqueViolation: ERROR: duplicate key value violates unique constraint?

我有一个模型Post,每次创建帖子时,我都希望同时创建一个新的Moderation实例。所以在post.rb中我使用回调after_save:create_moderation然后写一个私有(private)方法:...includeReportableafter_save:create_moderationprivatedefcreate_moderationself.create_moderation!(blog:Blog.first)end但是在创建提案时出现此错误:PG::UniqueViolation:ERROR:duplicatekeyvalueviolatesunique
