【问题描述】:
我正在将旧项目从 Rails 2.3.2 升级到 2.3.16(由于最近公开的漏洞),但是当我尝试访问任何模型上的 has_many 关联时,我得到来自sanitize_sql 的ArgumentError。
class User
has_many :games, :dependent => destroy
end
class Game
belongs_to :user
end
当我尝试调用 Game.last.user 时,它会返回正确的 User 对象,但调用 User.last.games 时会出现以下错误堆栈:
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这个问题,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。
【问题讨论】:
-
你的 ree 版本的补丁级别是多少?使用 ree1.8.7-2012.02 是否仍然出现相同的错误?我对 ree-1.8.7-2011.12 有一些问题
-
我使用的是 ruby-1.8.7-p371,但我会试试 ree 看看是否有帮助。
-
不,更改为 ree-1.8.7-2012.02 似乎并没有解决问题。
