Django FeinCMS and page extensions issue

Question

I'm experimenting with Page extensions and FeinCMS 1.2.1.

I'd like to create this simple page extension:

from django.db import models

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

but I keep getting this error:

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

The package containing the extension is called dev.extensions and the module categories, I have added it to the Python path and the extension is registered with Page.register_extensions('dev.extensions.categories').

I'm wondering what I'm doing wrong, please help.

The complete stacktrace follows.

Answer 1

Maybe models is getting reassigned somewhere to another module before your register function gets run?

Try changing your code to this:

from django.db import models as django_models

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