Hi Nick,
I have checked all the documentations:
1. When I try to store the blob key in the IMG DB EXAPANDO, the app reach
the upload, but it seems to have problem before the self.redirect. I suppose
I can't do it here, but where can I do it? And how?
class ImgHandler(blobstore_handlers.BlobstoreUploadHandler):
def post(self):
upload_files = self.get_uploads('img')
self.redirect('/')
2. Is there way to store a link to the imagine stored in the blobstore? I
want to pass to the web framework just a link to the blobstore.
{% for img in immagini %}
<img src="/serve/{{ img.link }}" />
{% endfor %}
In my understanding I have always to have a link to the app that will
elaborate everything. Right?
Thanks
Max
