Mongoid日期（DateTime）字段无法正确解析以存储到数据库中
||
我已经遇到这个问题好几天了，却找不到任何解决方案。看来我无法更改Mongoid文档中字段的日期（＆DateTime）格式
class Project
include Mongoid::Document
field :deadline, :type => Date
end
p = Project.new
p.deadline = \"20-10-2011\"
p.deadline = \"20/10/2011\"
ArgumentError: invalid date

#this returns all the Date fields as an array def self.date_fields self.fields.map {|f,v| f if v.type == Date}.compact end def self.convert_dates #go through all the fields and define a method for each self.date_fields.each do |f| define_method \"#{f}=\".intern do |arg| #if there is a value if arg.present? begin #try to parse it the normal d/m/Y way new_date =Date.parse(arg) rescue #if it fails attempt the US format. Could add more formats by nesting #rescues new_date = DateTime.strptime(arg, \'%m/%d/%Y\') end #call super to let Mongoid handle it super(new_date) end end end亨尖玛次酥
将产生FALSE，but9ѭ将产生true， 通过将您的Mongoid更新到最新版本来解决此问题甲车劲
# our form sends in month, day, year def my_date=(*args) if args.first.is_a?(String) args[0] = Time.strptime(args[0], \"%m/%d/%Y\") end super(*args) end
