ruby-on-rails-4 – 枚举选项“新”无效

我试图在我的模型上创建一个枚举,我希望其中一个状态是“新的”

例如

enum status: { stale: 0,new: 1,converted: 2 }

似乎rails拒绝这个以下错误.

You tried to define an enum named "status" on the model "Lead",but this will generate a class method "new",which is already defined by Active Record.

我理解为什么会这样,但我想知道是否有办法解决这个问题？

解决方法

该错误清楚地表明您不能使用新密钥枚举,因为它将与现有的ActiveRecord方法冲突.没有办法解决这个问题.

这个问题并不新鲜,之前已经讨论过了.

我建议你阅读

enum: Option not to generate “dangerous” class methods

根据Rails合作者Godfrey Chan的说法：

In this case,if you want to use enum,you are probably better off
renaming your label to something else. This is not unique to enums – a
lot of Active Record features generates methods for you and usually
there aren’t ways to opt-out of those generated methods.

Gonna give this one a close for Now….
