Ruby on rails 升级到rails 3.2.0后堆栈级别太深

我正在将我的应用程序升级到最新的rails，并且遇到了堆栈级别太深的错误。当我从模型中发出ajax请求时，就会发生此错误。以下是错误和相关控制器/型号代码：

^^这就是调用.cal_entry model函数时出现错误的地方

型号

  scope :log_entry_for_date, lambda { |date1| where('date == ?', date1)}
  scope :log_entry_for_athlete, lambda { |athlete_id| where(:athlete_id => athlete_id)}

  def self.cal_entry(date, athlete_id)
    log_entry_for_date(date).log_entry_for_athlete(athlete_id).includes({:workouts => {:completed_workouts => :workout_times}})
  end

现在，这在rails 3.0中工作得非常好，但升级后会立即显示错误。我尝试升级到rails 3.2，但错误仍然存在

ruby 1.9.3p429

rails 3.2.0

谢谢你的帮助

该错误似乎是由训练模型中名为“method”（用于说明）的方法名称不正确引起的。我想在升级之前这不是问题。

LogEntry.cal\u entry（@date，@atternate.id）。size

实际上正在执行，根据正在吐出的sql。你能包括整个控制器方法吗？刚刚添加了整个方法。通过删除代码行，它看起来像是

@workouts=@log\u entry.workouts.build

，这是创建堆栈级别太深的错误，我的模型是有组织的，因此每个log\u条目都有许多训练，为什么会出现问题？请注意，

find\u by\u id

和

find

是相同的，而

\u by\u id

是隐含的<代码>用户。按用户id查找（参数[：运动员id]）应为

User.find（参数[：运动员id]）

。另外，我不知道为什么要使用

n

或

1.times

或

n+=2

。这些行对代码没有影响。你的方法应该是这样的：谢谢！这么干净。我最初进行迭代是因为我生成了两个时间域，但后来决定现在只显示一个，从而使代码变得毫无意义。谢谢，我还在学习更干净的代码！
