今天一大早爬起来就开始查找django 上传文件的例子。网上的例子不是写的太简单，就是不全面。现在终于自己解决了，并写了个小例子.
demo 介绍：使用mysql数据库，把每次上传的文件按照日期分类存放，并且把文件路径上传到mysql数据库中。
项目目录如下：
下面上代码：
myproject/urls.py: 用来存放整个项目的路径
# -*- coding: utf-8 -*-
from django.conf.urls import patterns, include, url
from django.conf import settings
from django.conf.urls.static import static
from django.views.generic import RedirectView
urlpatterns = patterns('',
(r'^myapp/', include('myproject.myapp.urls')),
(r'^$', RedirectView.as_view(url='/myapp/list/')), # Just for ease of use.
) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
myproject/settings.py:部分代码如下 设置数据库，及文件存放路径
import os
PROJECT_ROOT = os.path.realpath(os.path.dirname(__file__))
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
'NAME': '', # Or path to database file if using sqlite3.
# The following settings are not used with sqlite3:
'USER': 'root',
'PASSWORD': 'myproject',
'HOST': '127.0.0.1', # Empty for localhost through domain sockets or '127.0.0.1' for localhost through TCP.
'PORT': '3306', # Set to empty string for default.
'default-character-set' :'utf8',
}
}
HERE = os.path.dirname(__file__) #MEDIA_ROOT = HERE+STATIC_URL MEDIA_ROOT = os.path.join(PROJECT_ROOT, 'media') # URL that handles the media served from MEDIA_ROOT. Make sure to use a # trailing slash. # Examples: "http://media.lawrence.com/media/", "http://example.com/media/" MEDIA_URL = '/media/'
myproject/myapp/forms.py 自定义form
# -*- coding: utf-8 -*-
from django import forms
class DocumentForm(forms.Form):
docfile = forms.FileField(
label='Select a file',
help_text='max. 42 megabytes'
)
myproject/myapp/models.py 模板文件，设置存储路径
# -*- coding: utf-8 -*-
from django.db import models
class Document(models.Model):
docfile = models.FileField(upload_to='documents/%Y/%m/%d')
myproject/myapp/urls.py app 路径文件
# -*- coding: utf-8 -*-
from django.conf.urls.defaults import patterns, url
urlpatterns = patterns('myproject.myapp.views',
url(r'^list/$', 'list', name='list'),
)
myproject/myapp/views.py 文件上传 view.py
# -*- coding: utf-8 -*-
from django.shortcuts import render_to_response
from django.template import RequestContext
from django.http import HttpResponseRedirect
from django.core.urlresolvers import reverse
from myproject.myapp.models import Document
from myproject.myapp.forms import DocumentForm
def list(request):
# Handle file upload
if request.method == 'POST':
form = DocumentForm(request.POST, request.FILES)
if form.is_valid():
newdoc = Document(docfile = request.FILES['docfile'])
newdoc.save()
# Redirect to the document list after POST
return HttpResponseRedirect(reverse('myproject.myapp.views.list'))
else:
form = DocumentForm() # A empty, unbound form
# Load documents for the list page
documents = Document.objects.all()
# Render list page with the documents and the form
return render_to_response(
'myapp/list.html',
{'documents': documents, 'form': form},
context_instance=RequestContext(request)
)
myproject/myapp/templates/myapp/list.html 文件列表及上传页面
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Minimal Django File Upload Example</title>
</head>
<body>
<!-- List of uploaded documents -->
{% if documents %}
<ul>
{% for document in documents %}
<li><a href="{{ document.docfile.url }}">{{ document.docfile.name }}</a></li>
{% endfor %}
</ul>
{% else %}
<p>No documents.</p>
{% endif %}
<!-- Upload form. Note enctype attribute! -->
<form action="{% url "list" %}" method="post" enctype="multipart/form-data">
{% csrf_token %}
<p>{{ form.non_field_errors }}</p>
<p>{{ form.docfile.label_tag }} {{ form.docfile.help_text }}</p>
<p>
{{ form.docfile.errors }}
{{ form.docfile }}
</p>
<p><input type="submit" value="Upload" /></p>
</form>
</body>
</html>
数据库设计：
建立一个myproject数据库，并建立一个myapp_document表。 设置两个字段id int类型；docfile varchar类型。
表结构如下：
先存入几张图片：
好了现在已经到了测试时间了，
在浏览器中输入：http://localhost:8000/myapp/list
运行结果如下：
