    1、URL

    urlpatterns = patterns('',

       url(r'^$', views.index, name='index'),

       url(r'^(?P<poll_id>\d+)/$', views.detail, name='detail'),

       url(r'^(?P<poll_id>\d+)/results/$', views.results, name='results'),

       url(r'^(?P<poll_id>\d+)/vote/$', views.vote, name='vote'),

    url(r'^upload/$', views.upload_file, name='upload'),

    )


    2、FORM类

    vi forms.py

    from django import forms


    class UploadFileForm(forms.Form):

       title = forms.CharField(max_length = 50)

       file = forms.FileField()


    3、视图：

    －－上传处理

    def handle_uploaded_file(f,title):

       filename = "name.txt"

       if title != "":

           filename = title

       print "upload file's name is " + f.name

       with open('/tmp/'+filename,'wb+') as destination:

           for chunk in f.chunks():

               destination.write(chunk)


    def upload_file(request):

       if request.method == 'POST':

           form = UploadFileForm(request.POST, request.FILES)

           print "upload......"

           if form.is_valid():

               print "is valid........"

               handle_uploaded_file(request.FILES['file'],request.POST['title'])

               return HttpResponseRedirect('/success/url/')

       else:

           form = UploadFileForm()

       return render(request, 'polls/upload.html', {'form': form})


    4、模板 upload.html

    <html>

    <head>

    <title>file upload</title>

    </head>

    <body>

    <form enctype="multipart/form-data" method="post" action="{% url 'polls:upload' %}">{% csrf_token %}

    File Name:<input type="text" name="title" /><br />

    <input type="file" name="file"/><br />

    <input type="submit" value="upload" />

    </form>

    </body>

    </html>
