Hi Vik,
This should be possible with appengine and Google Docs, but it may
not be easy.
For any Google account you have 1GB of Google Docs usage free and
additional
storage is $0.25 per GB, so you could be creative with storing files
(securely) and or
moving them to other backup.
Here's how it could be done:
For 'creating a PDF' you would actually create or edit a Google
Docs document on the fly
and keep that stored in Google Docs. (Google Documents List API...
Creating a permanent
generic version of the document and making a copy and editing the copy
on the fly would be easiest.)
In the email to the donor, you would give them a url that they will
use to download the file as a pdf.
That url for the pdf would not be the Google Docs url, but would be
a url to your appengine application.
That specific delivery url would have to not use Google authentication
(though the rest of your urls would continue to). For that delivery
url, you would have to implement your own programatic authentication
and authorization for that delivery url and supply donor specific auth/
auth to the donor in an easy to use manner.
Behind the scenes in your app: Since your application is already
authenticated with Google
and authorized to access your Google Docs, you would read the PDF
export stream directly
into the response stream to the donor. A brief look at the Google
Documents List API
suggests that that's possible, but I haven't tried it.
Cheers,
Nichole
