Could you help me? I can't upload files!!!
This is my code:
----------
upurl = blobstore.create_upload_url('/upload')
----------
<form method="post" action={{ upurl }} enctype="multipart/form-data"/>
Upload a picture: <input type="file" name="File"/><br>
Caption: <input type="text" name="Frase"/>
<input type="hidden" name="domain" value="{{ domain }}"/>
<input type="submit"/>
</form>
----------
class UploadHandler(blobstore_handlers.BlobstoreUploadHandler):
def post(self):
upload_files = self.get_uploads('File')
blob_info = upload_files[0]
self.request.get('Nick')
frasi = FRASI()
frasi.frase = self.request.get('Frase')
frasi.gruppo = self.request.get('domain')
frasi.link = blob_info.key()
frasi.Tlink = images.get_serving_url(frasi.link, 94)
frasi.Glink = images.get_serving_url(frasi.link, 400)
frasi.put()
self.redirect("/" + self.request.get('domain') + "/fanpage")
