我从 Mac OS X 10.7 上的端口安装了 Django 1.4.1 和 Python 2.7。当我尝试运行 manage.py runserver 8000 时，出现错误：

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):

    num_errors = get_validation_errors(s, app)

    __import__(name)

    class Photo(models.Model):
  File "/Users/rankor777/PycharmProjects/PyCart/PyCartApp/models.py", line 41, in Photo
    title = models.Model(max_length=128)
  File "/Library/Python/2.7/site-packages/django/db/models/base.py", line 289, in __init__
    if args_len > len(self._meta.fields):
AttributeError: 'Model' object has no attribute '_meta'

这是什么，如何解决？

我不知道您为什么认为这与 MacPorts 有关。回溯显示错误，该错误位于第 41 行PyCartApp/models.py：你已经把models.Model(max_length=128)我认为你打算放的地方models.CharField(max_length=128)。
