Answer 1

Here's a simple example to get you started...

query = db.GqlQuery("SELECT * FROM Item ORDER BY date DESC")
cursor = self.request.get('cursor')
if cursor: query.with_cursor(cursor)
items = query.fetch(30)
cursor = query.cursor()

... your regular output ...

self.response.out.write('<a href="yoururl?cursor=%s">Next Page</a>' % cursor)
