如何干燥 Mongoid 模型的共享范围？

我有一些 Mongoid 模型类，它们都有一个 :datetime 字段。我想查询这些模型以找出属于今天日期的记录。查询如下所示：

scope today, where(:datetime.gt => DateTime.now.beginning_of_day, :datetime.lt => DateTime.now.end_of_day)

目前，上述范围代码在所有模型类中重复。我怎样才能把它弄干呢？

原文

I have a few Mongoid model classes that all have a :datetime field. I would like to query these models to find out records that fall under today's date. The query would look like this:

scope today, where(:datetime.gt => DateTime.now.beginning_of_day, :datetime.lt => DateTime.now.end_of_day)

Currently, the above scope code are duplicated within all the model classes. How do I dry this up?

最简单的事情是：

module TimeDepedentent
  field :datetime

  scope today, where(:datetime.gt => DateTime.now.beginning_of_day, :datetime.lt => DateTime.now.end_of_day)

  scope yesterday ...
  scope one_month_ago ...
end

class MyModel
  include TimeDepedentent
end

The simples thing is:

module TimeDepedentent
  field :datetime

  scope today, where(:datetime.gt => DateTime.now.beginning_of_day, :datetime.lt => DateTime.now.end_of_day)

  scope yesterday ...
  scope one_month_ago ...
end

class MyModel
  include TimeDepedentent
end
