在 Ruby on Rails 中查找后调用模型中的方法 [英] Call a method in model after find in Ruby on Rails

问题描述

我想知道是否可以在使用 find 后从模型中调用方法.

I would like to know if it is possible to call a method from a model after using find.

类似于after_save，但after_find.

谢谢，加布里埃尔.

推荐答案

对于 Rails >= 3，请参阅 @nothing-special-here

For Rails >= 3, see the answer from @nothing-special-here

有.不过，与 after_initialize 一起，after_find 是一个特例.你必须定义方法，after_find :some_method 是不够的.不过，这应该可行:

There is. Along with after_initialize, after_find is a special case, though. You have to define the method, after_find :some_method isn't enough. This should work, though:

class Post < ActiveRecord::Base
  def after_find
    # do something here
  end
end
