我在这里多次看到此错误，每次似乎都不同。 我正在开发一个带有传单的geodjango应用程序。自从我安装了传单以来，我收到此错误。 我在另一篇文章中骑了这个：
- 删除了对不带渲染器参数的 Widget.render(( 方法的支持。
有什么方法可以在不必返回版本 - 2.0.8 的情况下解决此问题？

尽管仅注释boundfield.py中的第 97 行有效，但我通过导航到调用渲染函数的文件夹解决了这个问题。例如，通过在django_markdown文件夹中widgets.py文件中添加renderer=None解决了问题。
boundfield.py

我之前遇到过同样的问题，但没有找到任何修复方法，但我删除了 boundfield.py 文件中的"渲染器"行，该文件将是内联 92 只是删除它。
