google app engine - GAE (Python) form file upload + email file as attachment -

i need implement rather simple web form on google app engine (gae-python) accepts form input (name, email, telephone) , resume (typically txt, pdf or doc/docx) file. once form submitted, want contents of form emailed , if file submitted in form, included attachment in same email designated email address.

1. i don't need file exist after emailed/attached. sort of temp file, or stored in temp blob store.
2. with html5 , jquery, there lot of fancy user interfaces implement file uploads. there recommended approach use 1 of these work nicely gae, being able degrade gracefully if browser not support modern methods (namely ie)?

i using jinja2 framework, if relevant. (i python novice way)

thanks in advance!

for upload file blob in gae need blobstore_handlers built-in framework called webapp. docs have complete sample upload files , not think there other ways upload blobstore.

when have blob see first sample of page docs attach blob email.

now, "temp file solution" can try different way: write upload file ram stringio python module. that:

<form action="/test/" method="post" enctype="multipart/form-data">   <input type="file" name="file"><br>   <input type="submit"name="submit" value="submit"> </form> 

def post(self):     output = stringio.stringio()     upload = self.request.get('file')     output.write(upload)     self.response.write(output.getvalue())
