Django文件上传与下载(FileFlid)

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
