Hi,
Send a parameter named "page" from url like "page=1", "page=2" and handle
it in Post method.
You can return records from list like result_list[from_indice:to_indice]
For example:
from_indice = 10
to_indice = 20
It will return records between 10 to 20.
def POST(self):
result_list = [bla bla 200 records]
i = web.input(page=1)
RECORDS = 10
return render.recordslist(result_list[(page - 1) * RECORDS :
page * RECORDS])
