Django管理问题

Question

当我尝试访问django管理默认应用程序时，我有以下堆栈跟踪。有人知道怎么修吗？我已经在我的models.py中为目录应用程序清楚地定义了字段date_created。我不确定我还需要在哪里定义它？

Answer 1

我的猜测是，您已经在models.py字段中设置了auto_now_add或auto_add，因此它不是表单中要排除的一部分。

尝试从您的exclude语句中删除它。

Answer 2

您是在初始syncdb之后进行更改的吗？如果是这样的话，您需要在有问题的应用程序上执行reset，以便删除、重新创建和(如果您有fixture)重新加载这些表。

或者，您可以进入您的应用程序的dbshell并使用SQL自己修改该表。

Answer 3

我也犯了同样的错误。我回到了我有一段时间没有处理的项目上。我用django==1.5而不是django==1.6来运行它，因为它可以正常工作。

所以总而言之，在我的例子中，它是与1.5上的django版本连接的，我得到的错误如下：ExhibitorAdmin.exclude' refers to field 'collectedcontact' that is missing from the form.

然而，当我切换到django==1.6时，这个问题马上就消失了。
