Ruby on rails 验证\u是否包含\u验证时区的错误,ruby-on-rails,ruby-on-rails-4,Ruby On Rails,Ruby On Rails 4,我在代码中添加了一个代码片段，以验证用户是否正确通过我表单中的时区，但它不起作用，出现以下错误： ArgumentError in VideosController#index An object with the method #include? or a proc, lambda or symbol is required, and must be supplied as the :in (or :within) option of the configuration hash 代码片段是

我在代码中添加了一个代码片段，以验证用户是否正确通过我表单中的时区，但它不起作用，出现以下错误：

ArgumentError in VideosController#index
An object with the method #include? or a proc, lambda or symbol is required, and must be supplied as the :in (or :within) option of the configuration hash

代码片段是：

validates_inclusion_of :time_zone, :in => ActiveSupport::TimeZone.zones_map { |m| m.name }, :message => "is not a valid Time Zone"

我从博客上下载的，所以我不知道为什么它不起作用。如果有区别的话，我使用的是rails 4。多谢各位
