Hi,

i have created two fields.

assigned_date = fields.Datetime(string='Assigned Date',
    default=fields.Datetime.now,
    index=True, copy=False)

assigned_user_id = fields.Many2one('res.users', string='Assigned Employee Name',
        default=lambda self: self.env.uid,
        index=True, track_visibility='onchange')

name = fields.Char('Equipment Name', required=True, translate=True)

Once the Equipment is assigned to Employee on a perticular date thats Assigned Date automatic mail has to go to Assigned Employee and Project manager ..

How to do this?
