有没有办法在模型中定义无效的枚举值？

Question

我有一个模型：

class CashPayment < ActiveRecord::Base

 .....

 **enum status: [:processing, :paid, :invalid,:refund]**
end

在这里，我已经宣布cash_payment的无效状态。但它给我的错误如下：

*** ArgumentError Exception: You tried to define an enum named "status" on the model "CashPayment", but this will generate a instance method "invalid?", which is already defined by Active Record

Answer 1

invalid?已由ActiveRecord定义。

您的枚举status还包含:invalid，其中提供的方法为invalid?

现在生成两个invalid?方法时存在冲突。

尝试为:invalid提供另一个名称，例如:invalid_rec

enum status: [:processing, :paid, :invalid_rec,:refund]
