File Uploading In Google Application Engine Using Django
- by Ayush
I am using gae with django.
I have an project named MusicSite with following url mapping-
urls.py
from django.conf.urls.defaults import *
from MusicSite.views import MainHandler
from MusicSite.views import UploadHandler
from MusicSite.views import ServeHandler
urlpatterns = patterns('',(r'^start/', MainHandler),
        (r'^upload/', UploadHandler),
        (r'^/serve/([^/]+)?', ServeHandler),
)
There is an application MusicSite inside MusicFun with the following
codes-
views.py
import os
import urllib
from google.appengine.ext import blobstore
from google.appengine.ext import webapp
from google.appengine.ext.webapp import blobstore_handlers
from google.appengine.ext.webapp import template
from google.appengine.ext.webapp.util import run_wsgi_app
def MainHandler(request):
     response=HttpResponse()
     upload_url = blobstore.create_upload_url('http://localhost:
8000/upload/')
     response.write('')
     response.write('' % upload_url)
     response.write("""Upload File:   """)
     return HttpResponse(response)
def UploadHandler(request):
     upload_files=request.FILES['file']
     blob_info = upload_files[0]
     response.redirect('http://localhost:8000/serve/%s' %
blob_info.key())
class ServeHandler(blobstore_handlers.BlobstoreDownloadHandler):
 def get(self, resource):
     resource = str(urllib.unquote(resource))
     blob_info = blobstore.BlobInfo.get(resource)
     self.send_blob(blob_info)
now whenever a upload a file using /start and
click Submit i am taken to a blank page with the following url-
localhost:8000/_ah/upload/ahhnb29nbGUtYXBwLWVuZ2luZS1kamFuZ29yGwsSFV9fQmxvYlVwbG9hZFNlc3Npb25fXxgHDA
These random alphabets keep varying but the result is same. A blank
page after every upload.
Somebody please help.
