同13，但是Admin后台是通过数据库方式，所以先要
一.vim blog/models.py
from django.db import models
class User(models.Model):
username = models.CharField(max_length=30)
headImg = models.FileField(upload_to='./upload/') #文件的上传目录
def __unicode__(self):
return self.username
二.vim settings.py
打开INSTALLED_APPS下面的django.contrib.admin
三.vim urls.py
打开from django.contrib import admin和admin.autodiscover()和url(r'^admin/',include(admin.site.urls)),
四.python manage.py syncdb
五.vim blog/admin.py
from django.contrib import admin
from blog.models import User
admin.site.register(User)
3.python manage.py runserver
4.web端测试
