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.
