更新到1.11:TypeError build_attrs()最多接受2个参数(给定3个) [英] Update to 1.11: TypeError build_attrs() takes at most 2 arguments (3 given)

问题描述

我从1.10.7更新到1.11.0，并且在查看表单时遇到以下错误.我根本无法理解我的表格有什么问题.其他形式的工作方式相同.我怀疑这可能与 select2 或

I a updating from 1.10.7 to 1.11.0 and I am getting the following error when viewing a form. I cannot fathom what is wrong with my form at all. Other forms work in the same way. I suspect that it could be an interaction with either select2 or markdownx but there is no indication that those are incompatible with 1.11.

如何进一步调试?

推荐答案

他们更改了Django 1.11/

They changed the build_attrs function in Django 1.11/

您可能还需要使用pip升级select2和markdownx.

You may need to upgrade also select2 and markdownx with pip.

<代码>pip install select2 markdownx-升级
