Question

我的模型包含一个名为“status”的字段。我已将其更改为DB中的字符串类型。我还在AASM中使用枚举。
这是我的代码：

private double? GetNumber()
{
    double? result = null;
    try {
        result = Convert.ToDouble (Console.ReadLine ());
    } catch (System.FormatException) {
        Console.Beep ();
        Console.WriteLine ("");
        Console.WriteLine ("You have entered an invalid number!");
        Console.WriteLine ("");
    }
    return result;
}

...
// prompt for first number
double? num1 = null;
while (!num1.HasValue)
{
   Console.Write ("What is the first number? ");
   num1 = GetNumber();
}
// prompt for second number
double? num2 = null;
while (!num2.HasValue)
{
   Console.Write ("What is the second number? ");
   num2 = GetNumber();
}
// calculate result
answer = num1.Value + num2.Value;

我这样申请：

class Card < ActiveRecord::Base
  include AASM

  enum status: {
    default: 0,
    published: 1,
    deleted: 2
  }

  aasm column: :status, enum: true, skip_validation_on_save: true, no_direct_assignment: true do
    state :default, initial: true
    state :published
    state :deleted

    event :publish do
      transitions from: :default, to: :published
    end

    event :delete do
      transitions from: :published, to: :deleted
    end
  end
end

无论我拨打Card card = Card.first card.publish还是card.publish，我都会收到如下错误：

card.delete

这让我困惑了几天。任何帮助都会受到赞赏。

不应该是

enum status: [
  :default,
  :published,
  :deleted
]

？如果这没有帮助，请打开open an issue on GitHub，我会仔细查看它。
