Question

我看到了意想不到的事情，我无法解释。

我有以下代码：

<% unless task.complete %>
... do stuff ...
<% end %>

这可以按预期显示不完全属于父对象的任务对象。然而，在一个，只有一个案例，它没有。如果它不起作用，则抛出以下错误：

undefined method `encoding' for 1:Fixnum

Extracted source (around line #1):

1 <% unless task.complete %> 
2
3
4

代码始终有效，但只有一种情况。失败的情况是当一个特定的父对象被呈现时。父对象不起眼。它有完成和不完成的任务。但是其他父对象也是如此，但只有一个父对象产生错误。

有什么想法吗？

提前致谢！
