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：
接下来是下载
我的文件目录是：
要想下载你首先要知道，你上传的东西到了哪个目录，涉及到两个地方：
MEDIA_ROOT = HERE
