问题描述
这是模特:
author = models.ManyToManyField(Author)
modelAdmin: filter_horizontal =(作者"，)
modelAdmin:filter_horizontal=("author",)
它仍在呈现多选小部件.我不知道怎么了.
It's still rendering a multiple select widget.I don't know what's the problem.

推荐答案
我认为答案为时已晚.但是，我在阅读django核心书籍时遇到了同样的问题，我认为这可能是您提出问题的原因:
I think it's too late to answer; however, I ran into the same problem while reading django-core book which I think might be the source of your question:
只需在隐身模式下或在其他浏览器中打开管理面板，就可以通过从浏览器中删除缓存的内容来解决此问题.我认为问题可能是由于您在进行更改之前第一次未完全加载javascript.然而;以隐身-私人模式打开它为我解决了这个问题.
simply open the admin panel in incognito mode or in another browser, you can also get rid of the problem by removing cached content from your browser. I think the problem might stem from javascript incomplete loading for the first time prior to the changes you made. However; opening it in incognito-private mode solved the problem for me.
