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
