我试图将大型模型分成多个文件进行逻辑组织.所以我有两个文件：
model1.rb
class Model1 < ActiveRecord::Base
before_destroy :destroying
has_many :things,:dependent=>:destroy
def method1
...
end
def method2
...
end
end
require 'model1_section1'
model1_section1.rb
class Model1
def method3
...
end
def self.class_method4
...
end
end
但是当应用程序加载时,并且有一个对Model1.class_method4的调用,我得到：
undefined method `class_method4' for #<Class:0x92534d0>
我也试过这个要求：
require File.join(File.dirname(__FILE__),'model1_section1')
我在这里做错了什么？
解决方法
我知道我稍晚回答这个问题,但是我刚才在我的一个应用程序中做了这个,所以以为我会发布我使用的解决方案.
让我们这是我的模特儿：
class Model1 < ActiveRecord::Base # Stuff you'd like to keep in here before_destroy :destroying has_many :things,:dependent => :destroy def method1 end def method2 end # Stuff you'd like to extract before_create :to_creation_stuff scope :really_great_ones,#... def method3 end def method4 end end
您可以将其重构为：
# app/models/model1.rb require 'app/models/model1_mixins/extra_stuff' class Model1 < ActiveRecord::Base include Model1Mixins::ExtraStuff # Stuff you'd like to keep in here before_destroy :destroying has_many :things,:dependent => :destroy def method1 end def method2 end end
和：
# app/models/model1_mixins/extra_stuff.rb
module Model1Mixins::ExtraStuff
extend ActiveSupport::Concern
included do
before_create :to_creation_stuff
scope :really_great_ones,#...
end
def method3
end
def method4
end
end
它的工作完美感谢ActiveSupport :: Concern给你的额外清洁.希望能解决这个老问题.
