django1.4上传文件简明攻略
创建upload项目
django-admin.py startproject upload
进入upload项目目录，创建home应用
cd upload ./manage.py startapp home
在home应用目录下创建一个模板目录
mkdir home/templates
进行项目基本设置
vi upload/settings.py
- 添加home应用
INSTALLED_APPS = ( # ... 'home', ) - 添加home应用的模板目录
import os #... TEMPLATE_DIRS = ( # ... os.path.join(os.path.realpath(os.path.dirname(__file__)), 'home/templates'), )
进行项目url配置
vi upload/urls.py
urlpatterns = patterns('',
# ...
url(r'^$', 'home.views.index', name='home'),
url(r'^upload', 'home.views.upload'),
)
编辑home应用的views.py文件
vi home/views.py
from django.views.decorators.csrf import csrf_protect
from django.shortcuts import render_to_response, render
@csrf_protect
def index(request):
"""docstring for index"""
return render(request, 'index.html', {'title': 'test page'})
def upload(request):
if request.method == 'POST':
f = handle_uploaded_file(request.FILES['pic'])
return render_to_response('upload.html', {'file':f})
def handle_uploaded_file(f):
with open(f.name, 'wb+') as info:
for chunk in f.chunks():
info.write(chunk)
return f
在home应用的templates中添加两个模板文件
index.html
<!DOCTYPE HTML>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>{{ title }}</title>
</head>
<body>
<h1>Upload File</h1>
<form action="/upload" method="post" enctype="multipart/form-data" accept-charset="utf-8">
{% csrf_token %}
<input type="file" name="pic" value="" />
<button>Submit</button>
</form>
</body>
</html>
upload.html
<!DOCTYPE HTML>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>Upload Successed</title>
</head>
<body>
<h1>Upload file successed.</h1>
<pre>
filename: {{ file.name }}
filesize: {{ file.size }} bytes
</pre>
<a href="/">back</a>
</body>
</html>
