用django做博客，原本是可以用的，博客是项目下的一个app。后来我把博客升级为项目，不再做为为项目下一个app，做了一些修改。出现了如下错误。所有页面都是类似错误。

email = models.EmailField()

return self.name
class Blog(models.Model):
caption = models.CharField(max_length=50)
author = models.ForeignKey(Author)
tags = models.ManyToManyField(Tag, blank=True)
content = models.TextField()
publish_time = models.DateTimeField(auto_now_add=True)

update:答案在这里。http://stackoverflow.com/questions/4382032/defining-a-model-class-in-django-shell-fails
经过查阅资料：
要使用model必须要有app，新建app里面可以没有url.py，这样不影响url简短
