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….
