hi, i want to limit  display to 15 items, but i don't know how to create pagination in order to show all the rest of the records.

controllers.py : 

@http.route('/coopaname_helpdesk/liste_offres', type ='http', auth='public', website=True)
def liste_offres(self):

tickets = request.env['monmarchepublic'].sudo().search([] ,limit=15)
    return http.request.render('coopaname_helpdesk.liste_offres', {'tickets': tickets })

my template.xml : 

<?xml version="1.0" encoding="utf-8"?>
<odoo>
  <data>
    <record id="liste_offres" model="ir.ui.view">
        <field name="name">coopaname_helpdesk.marchepublic</field>
