Hello,

I'm trying to make a module to manage travel leaves for employees.

What I need t do is adding extra float field in hr.employee module of 'available_tickets' . To be allocated from other module named "travel_request". How t do this?

Here's my code:

class hr_employee(osv.osv):
    _inherit="hr.employee" 
    _columns = {
         'available_tickets': fields.float("Available Tickets"),
    }

class travel_request(osv.osv):
    _name = 'travel.request'
    def _get_tickets(self, cr, uid, ids, context=None):
        emp_ticket = self.pool.get('hr.employee').browse(cr, uid, ids)
        return emp_ticket.available_tickets
    _columns = {
        'no_tickets': fields.function(_get_tickets, string='Number of Tickets', type='float'),
     }
