我是 django 的新手，我正在使用django-taggit 0.10a1 在我的 django 1.4.2 应用程序中标记功能。我也尝试了 django-tagging 应用程序，但由于该项目没有得到维护，并且 django-taggit 得到了开发人员的很多积极评价，我选择了它。
我想知道你们中的任何人是否可以帮助我解决我看到的问题。遵循文档后，我添加了：
tags = TaggableManager()
我所有需要标记的模型。大多数模型自动在 django 管理中添加标签部分作为指定的文档，但对于某些模型，标签部分不会显示在管理 UI 上。我无法弄清楚为什么。这是我在所有字段之后声明的标签行的几个模型。如果您在我的模型中发现该语句的位置有任何错误，并且如果您发现任何问题可以告诉我，我将不胜感激。使用 TaggableManager 的示例非工作模型如下：
