Python Wagtail 崩溃 6.3.1“Streamfield 对象没有属性‘bind_to_model’

Question

（今天下午 4 点根据下面给出的评论进行编辑。）

将旧的 Wagtail 网站更新到当前版本时，我遇到此错误，位于

admin/panels/group.py

第 74 行：

AttributeError: 'StreamField' object has no attribute 'bind_to_model'

因为这显然是在 WagTail 软件中作为分发的，我很困惑。

Answer 1

该错误表明面板定义中有一个

StreamField

对象，例如

content_panels

。这是无效的 - 它应该只包含面板对象，例如

FieldPanel

。

作为 Wagtail 2.x 到 6.x 升级过程的一部分，您必须 将

StreamFieldPanel

的任何实例替换为普通的

FieldPanel

- 我最好的猜测是您在执行此操作时犯了一个错误，并且将

StreamFieldPanel

改为

StreamField

。
