ruby-on-rails - 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，我已宣布 cash_payment 的状态无效。但它给了我如下错误：

*** 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 定义ActiveRecord。

您的枚举status还包含:invalid提供一种方法为invalid?

现在生成两个invalid?方法时发生冲突。

试着给你的另一个名字:invalid，说:invalid_rec

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