Question

将我的Rails 3.2.12项目切换到Ruby 2.0.0无法通过测试：

NoMethodError:
  private method `initialize_dup' called for #<Receipt:0x007fe06c809428>

看起来initialize_dup现在是私有方法。

使用Rails 3.2.12和Ruby 2.0.0时，如何才能通过测试？

Answer 1

对于那些因担心可能带来的问题而担心升级到3.2.13的人，我在初始化文件中添加了这个：

# Because of the Ruby 2.0 privatizes the method and  Rails 3.2.12's use of it
# , and because Rails 3.2.13 (which has a fix) also could potentially
# introduce other bugs, we're adding this patch to fix the issue.
#
# Remove this if the project contains Rails >= 3.2.13
module ActiveModel
  class Errors
    public :initialize_dup
  end

  module Validations
    public :initialize_dup
  end
end

class ActiveRecord::Base
  public :initialize_dup
end

它已经发布请使用带有Rails 3.2.13.rc2的Ruby 2.0.0并修复了上述问题initialize_dup在此发布和更多修复中。
