我正在试验页面扩展和FeinCMS 1.2.1。

我想创建这个简单的页面扩展：

from django.db import models

def register(cls, admin_cls):
    cls.add_to_class(models.TextField())

但我不断收到此错误：

AttributeError: 'module' object has no attribute 'TextField'

调用包含扩展的包dev.extensions和模块categories，我已将其添加到 Python 路径，并且扩展已注册到Page.register_extensions('dev.extensions.categories').

我想知道我做错了什么，请帮忙。

完整的堆栈跟踪如下。

也许在您的注册功能运行之前模型正在某个地方重新分配给另一个模块？

尝试将您的代码更改为：

from django.db import models as django_models

def register(cls, admin_cls):
    cls.add_to_class('field_name_here', django_models.TextField())
