本文实例为大家分享了Django文件上传与下载的具体代码，供大家参考，具体内容如下

Django1.4

首先是上传：

#settings.py

MEDIA_ROOT = HERE#定义一个完整路径给 MEDIA_ROOT 以便让 Django在此处保存上传文件

MEDIA_URL = 'media'#定义 MEDIA_URL 作为该目录的公共 URL,要确保该目录对 WEB 服务器用户帐号是可写的

#model.py
 
#coding=utf-8
 
from django.db import models
class User(models.Model):
 username = models.CharField(max_length = 30)
 headImg = models.FileField(upload_to = 'update/%Y%m%d')
 
 def __unicode__(self):
 return self.username

#view.py
 
#coding=utf-8
 
from django.shortcuts import render_to_response
from django import forms
from django.http import HttpResponse
from django.template import RequestContext
from disk.models import User
 
# Create your views here.
class UserForm(forms.Form):
 username = forms.CharField()
 headImg = forms.FileField()
 
def register(request):
 if request.method == "POST":
 uf = UserForm(request.POST, request.FILES)
 if uf.is_valid():
  #获取表单信息
  username = uf.cleaned_data['username']
  headImg = uf.cleaned_data['headImg']
  #写入数据库
  user = User()
  user.username = username
  user.headImg = headImg
  user.save()
  return HttpResponse('upload ok!')
 else:
 uf = UserForm()
 ur= User.objects.order_by('id')
 return render_to_response('register.html',{'uf':uf}, context_instance=RequestContext(request))

前台使用{{uf.as_ul}}来展示form，如下：

#register.html
 
<html>
<head>
 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
 <title></title>
</head>
<a href="update/20140711/005zEPW4jw1eg3js7sil3g30500824al.gif" rel="external nofollow" >gao</a>
<body>
 <h1>register</h1>
 <form method="post" enctype="multipart/form-data" >
 {% csrf_token %}
 {{uf.as_ul}}
 <input type="submit" value="ok" />
 </form>
</body>
</html>

上传成功！

数据库中是这么个情况：
