Django FeinCMS和页面扩展问题

Question

我正在试验Page extensions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())

但是我一直收到这个错误：

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

包含该扩展的包名为dev.extensions，模块名为categories，我已将其添加到Python path中，并且该扩展已注册到Page.register_extensions('dev.extensions.categories')。

我想知道我做错了什么，请帮帮忙。

完整的堆栈跟踪如下。

Answer 1

也许在您的注册函数运行之前，模型会被重新分配到另一个模块？

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())
