使用django-autocomplete-light添加更多字段时出错 [英] Error adding more fields with django-autocomplete-light

问题描述

我遇到问题，我正在使用2个库: django-autocomplete-light 和 django-dynamic-formset . 两位非常擅长做他们的工作. 第一个用于自动完成，第二个用于使django表单集动态化. 但是，当您想加入这2个问题时，就会出现问题. 问题图片

I have a problem and I am using 2 libraries : django-autocomplete-light and django-dynamic-formset. The 2 are very good at doing their job. The first is used to do autocomplete and the second to make django formsets are dynamic. but when you want to join these 2 a problem occurs. Image of the problem

创建新字段时，将以这种方式添加它.

when a new field is created, it is added in that way.

有什么办法可以解决这个问题?我正在阅读，几乎没有信息

Is there any way to fix this? I was reading and there is little information

推荐答案

我最近在同时使用django-autocomplete-light和django-dynamic-formset插件时遇到了同样的问题.我发现的解决方案是在初始化表单集之前(即在打开<form>标记之前)将{{ detalleformset.media }}移动到.那为我解决了这个问题，并使其不再创建那些多余的不可点击的自动完成字段.

I had the same problem recently using django-autocomplete-light and the django-dynamic-formset plugin together. The solution I found is to move the {{ detalleformset.media }} to before you initialize the formset, i.e. before your opening <form> tag. That solved the problem for me and made it so that those extra unclickable autocomplete fields were no longer created.
