應用Rails核心固定本地

Question

我打的Rails 4.1.4中的錯誤是最近由固定Rails核心：Fix potenital infinite recursion in changed_for_autosave? #16640

我怎麼能暫時在這個局部修復補丁，直到我已經升級到Rails的版本有這個？解決方法是更改​​了activerecord/LIB/active_record/autosave_association.rb

我已經有AR ::基地的擴展，我從包括本身經由ActiveRecord::Base.send(:include, ActiveRecordExtension)

我試圖增加一個模塊內聯的初始化調用在該文件中用於更改方法的AutosaveAssociation。

更新

配置/ intializers/01_extensions.rb

require "active_record_extension" 

active_record_extension.rb

module ActiveRecordExtension 
    extend ActiveSupport::Concern 
    module ClassMethods 
    ... 
    end 

    module AutosaveAssociation 
    def nested_records_changed_for_autosave? 
     return false if @_nested_records_changed_for_autosave_already_called ||= false 
     @_nested_records_changed_for_autosave_already_called = true 
     begin 
     self.class._reflections.values.any? do |reflection| 
      if reflection.options[:autosave] 
      association = association_instance_get(reflection.name) 
      association && Array.wrap(association.target).any? { |a| a.changed_for_autosave? } 
      end 
     end 
     ensure 
     @_nested_records_changed_for_autosave_already_called = false 
     end 
    end 
    end # module Autosave 

end 
ActiveRecord::Base.send(:include, ActiveRecordExtension)

我會寫這樣的：

module ActiveRecord#Extension 
    module AutosaveAssociation 
    def nested_records_changed_for_autosave? 
     puts "new" 
    end 
    end 
end 

#ActiveRecord::Base.send(:include, ActiveRecordExtension) 

class A < ActiveRecord::Base 
    include ActiveRecord::AutosaveAssociation 

    def initialize 
    nested_records_changed_for_autosave? 
    end 
end 
A.new 
=> new
