在Django中导入模型时出错

Question

I got this traceback while importing my model in management/commands:

Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/home/vagrant/.virtualenvs/rsspainter/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 453, in execute_from_command_line
    utility.execute()

    from models import *

    kwargs = {"app_label": model_module.__name__.split('.')[-2]}
  IndexError: list index out of range

What's wrong?? Django admin page works great.
My model:

class SeoUser(models.Model):
    '''
    Model of user.
    '''

    SEX = (
        ('M', 'Male'),
        ('F', 'Female'),
    )
    THEME_CHOICES = (
        ('auto', u'Автомобили'),
        ('tourism', u'Туризм'),
        ('cooking', u'Готовка'),
        ('gambling', u'Гэмблинг'),
        ('games', u'Онлайн игры'),
        ('business', u'Бизнесс'),
        ('amusement', u'Развлечения'),
        ('sports', u'Спорт и здоровье'),
        ('nyan', u'Животные'),
        ('quotes', u'Цитатники'),
        ('humor', u'Юмор'),
        ('women', u'Женские секреты'),
    )
    name = models.CharField("Name", max_length=100, blank=False)
    surname = models.CharField("Surname",max_length=150, blank=False)
    password = models.CharField("Password", max_length=16)
    country = models.CharField("Country", max_length=25)
    town = models.CharField("Town", max_length=35)
    is_real = models.BooleanField("Real user", default=False)
    sex = models.CharField("Sex", max_length=1, choices=SEX)
    age = models.IntegerField("Age", blank=False)
    thematics = models.CharField("Specification", max_length=15, choices=THEME_CHOICES, default='amusement')

    def __unicode__(self):
        return "%s-%s" % (self.name, self.thematics)
    # links to related models
    def email_count(self):
        return self.email.count()
    email_count.short_description = 'Email accounts'

    def blog_count(self):
        return self.blog.count()
    blog_count.short_description = 'Blogs'

    def twitter_count(self):
        return self.twitter.count()
    twitter_count.short_description = 'Twitter accounts'

Answer 1

You gave Django a top-level module, where it expects models to be part of a package. The error is the result of Django looking for the package name, and it doesn't exist here.

Do not add the package your models.py file lives in to the PYTHONPATH; only add directory where the parent package lives, here Project/apps .
