I have a model class in my Rails application called: UserAction In that model I have a constant (which I use as an enum):
class UserAction < ActiveRecord::Base
end
class UserActionType
ACTION1 = "action1"
ACTION2 = "action2"
end
当我试图利用这一不变的话:
if some_action == UserActionType::ACTION1
在申请控制人中,我有以下错误:
NameError (uninitialized constant ApplicationController::UserActionType)
任何想法?
查阅<代码>UserActionType类别,实际上,你需要填写文件。 对于模型或自动化载荷被配置的地方,铁路通过自动卸载文件而更容易。 例如,如果遇到<代码>UserAction, 铁路是指在模型中或在您有自动配置和要求自动存档的地方,称为用户——行动.rb。 因此,就你而言,你可以在<条码>用户_action_type.rb上,在<条码>上填写申请/模版<代码>和贴在<条码>上的
