python - django filter_horizo​​ntal无法显示

Question

这是模型:

author=models.ManyToManyField(作者)

模型管理员:filter_horizo​​ntal=("作者",)

它仍在渲染一个多选小部件。不知道出了什么问题。

我认为现在回答已经太晚了；但是，我在阅读 django-core 书时遇到了同样的问题，我认为这可能是您问题的根源:

只需以隐身模式或其他浏览器打开管理面板，您也可以通过从浏览器中删除缓存内容来解决该问题。我认为问题可能源于在您进行更改之前第一次 JavaScript 加载不完整。然而;以隐身模式打开它解决了我的问题。
