Mongoid /輕便摩托車得到保存的月份無效日期

Question

我想有DateTimes與月份的無效日期進行驗證。我使用Mongoid 4alpha2與軌道4，並在我的模型我有一個

field :date_of_birth, type: DateTime

當我做了定期從控制器與「1988年2月30日」一DATE_OF_BIRTH「創造」時，模型被保存爲date_of_birth爲「1988/03/1」，而不是獲取DateInvalid錯誤，就像常規的DateTime.new（1988,2,30）將在rails控制檯中一樣。我不確定腳踏車或mongoid是否繞過DateTime上的Rails驗證，是否有其他人遇到過這種情況？

看起來像Mongoid離開日期解析到MongoDB。檢查它在MongoDB的外殼：

> new Date('1988/02/30') 
ISODate("1988-03-01T08:00:00Z") 

這是完全可以接受的行爲JavaScript's Date constructor：

注：圖中日期被稱爲具有一個以上參數的構造，如果值低於其合理的範圍更大（例如，13爲月份值或70爲分鐘值），相鄰值將被調整。例如。 new Date(2013,13,1)相當於new Date(2014,1,1)，兩者都創建日期爲2014-01-01。對於其他值也是如此：new Date(2013,2,1,0,70)相當於new Date(2013,2,1,1,10)，它們都創建了一個日期2013-02-01T01:10:00。

至於象MongoDB是關心，1988/02/30是1988年加2個月加30天，自1988年是閏年，二月加30年3月1日天。

無論如何，您應該使用:type => Date作爲出生日期。當然，Date具有相同的「把它像JavaScript」行爲：

class M 
    include Mongoid::Document 
    field :d, :type => Date 
end 

m = M.create(:d => '1988/02/30') 
m.d 
# Tue, 01 Mar 1988 

，這樣沒有太大的幫助。

你可以報告一個bug，看看Mongoid人對此有何想法。在此同時，如果需要更嚴格的分析，你可以自己做：

field :date_of_birth, :type => Date 

def date_of_birth=(date) 
    super(Date.parse(date)) 
end 

然後，當你說Model.create(:date_of_birth => '1988/02/30')你會得到你的異常。
