Django FeinCMS与页面扩展问题

Question

我正在尝试使用页面扩展和FeinCMS 1.2.1版本。

我想创建一个简单的页面扩展：

from django.db import models

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

但是我总是遇到这个错误：

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

包含这个扩展的包叫做dev.extensions，模块是categories，我已经把它添加到Python的路径中，并且通过Page.register_extensions('dev.extensions.categories')注册了这个扩展。

我在想我哪里做错了，请帮帮我。

完整的错误追踪信息如下。

Answer 1

可能在你的注册函数运行之前，模型在某个地方被重新分配给了另一个模块？

试着把你的代码改成这样：

from django.db import models as django_models

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