我正在将一个遗留项目从 Rails 2.3.2 升级到 2.3.16（由于最近公开的漏洞），但是当我尝试访问has_many任何模型上的关联时，我得到一个ArgumentErrorfrom sanitize_sql.

class User
  has_many :games, :dependent => destroy
end

class Game
  belongs_to :user
end

当我尝试调用Game.last.user它返回正确的User对象，但调用User.last.games我得到以下错误堆栈：

ArgumentError: wrong number of arguments (2 for 1)

我在 Ruby 1.8.7 上运行 Rails 2.3.16；如果我遗漏了任何其他可能有助于诊断问题的详细信息，请告诉我。

编辑

我似乎已经通过编辑文件中的错误行来临时解决这个问题，activerecord-2.3.16/lib/active_record/associations/association_proxy.rb如下所示：

# Forwards the call to the reflection class.
def sanitize_sql(sql, table_name = @reflection.klass.quoted_table_name)
  @reflection.klass.send(:sanitize_sql, sql) #, table_name)
end

显然，我更喜欢更长期的解决方案，因为我不能 100% 确定这不会产生额外的连锁问题。

我有同样的问题，找不到是什么原因造成的。

我也得出了编辑这一行的结论。我做了一个猴子补丁初始化程序：

module ActiveRecord
  module Associations
    class AssociationProxy #:nodoc:
      def sanitize_sql(sql, table_name = @reflection.klass.quoted_table_name)
        @reflection.klass.send(:sanitize_sql, sql)#, table_name)
      end
    end
  end
end

我希望我能尽快找到真正的原因，因为这不应该是必要的。你的问题还有进展吗？
