i have:

class CalendarEvent(models.Model):
_name = 'calendar.event'

and

class Lead(models.Model):
_name = 'crm.lead'
meeting_ids = fields.Many2many('calendar.event')

and i need to override the create method on calendar.event so that when a new envent is created, is automaticlly insrted into meeting_ids
i've tried with:
​leads = self.env['crm.lead']
for lead in leads:
    lead.meeting_ids = [(0, 0, {'name': self.name,
'start': self.start,
'stop': self.stop})
 or with
lead.meeting_ids = [(4, self.id)] ​  ​
​

butnothing works, can anyone help me?
