这个问题似乎有很多潜在的解决方案,但似乎没有什么对我有用.
运行python manage.py runserver很好,但我在尝试运行时遇到错误django-admin.py- 使用任何选项.我其实是想做一个django-admin.py dumpdata myapp.

% …使用Django(一般来说是新手,一般是Python的新手)来做一个非常基本的联系人数据库.
尝试通过Admin页面将记录添加到Contributor表,其模型代码为:
class Contributor(models.Model):
first_name = models.CharField(max_length=20)
last_name = models.CharField(max_length=20)
organisation = models.ForeignKey('Organisation')
mode = models.CharField(max_length=10, blank=True)
email = models.CharField(max_length=30, blank=True)
landline = models.CharField(max_length=10, blank=True)
def __unicode__(self):
print('%s %s' % (self.first_name, self.last_name))
我得到的错误消息是:
