You can get the form data through
self.request.get("name")
and give the object proper property.
for example, in the html
<form action="/submit" method="post">
<input name="a">
<input name="b">
<input type="submit" value="Post">
</form>
in the server side, you write,
class Submit(webapp.RequestHandler):
def post(self):
a = self.request.POST.get('a')
b = self.request.POST.get('b')
object = Object()
object.a=a
object.b=b
object.put()
