Question

我正在将遗留项目从Rails 2.3.2升级到2.3.16（由于最近公布的漏洞），但当我尝试访问任何模型上的has_many关联时，我从ArgumentError获得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时，它返回正确的User对象，但是调用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;如果我遗漏了任何可能有助于诊断问题的其他细节，请告诉我。

修改

我似乎暂时通过编辑activerecord-2.3.16/lib/active_record/associations/association_proxy.rb文件中的错误行来解决此问题，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，我会更喜欢更长远的解决方案，因为我不能100％确定这不会产生额外的连锁问题。

Answer 1

我有同样的问题，但找不到导致它的原因。

我也得到了编辑这一行的结论。我做了一个猴子补丁初始化器：

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？
