Question

I have Django 1.4.1 and Python 2.7 installed from ports on Mac OS X 10.7. When I try to run manage.py runserver 8000, I’m getting an error:

Unhandled exception in thread started by <bound method Command.inner_run of <django.contrib.staticfiles.management.commands.runserver.Command object at 0x10bb840d0>>
Traceback (most recent call last):

    title = models.Model(max_length=128)

    if args_len > len(self._meta.fields):
AttributeError: 'Model' object has no attribute '_meta'

What’s this, and how to fix it?

Answer 1

I don’t know why you think this has something to do with MacPorts. The traceback shows the error, which is in line 41 of PyCartApp/models.py: you’ve put models.Model(max_length=128) where I presume you meant to put models.CharField(max_length=128).
