python code for age calculation from date of birth:

from datetime import datetime from dateutil import parser

class mark_marksheet(osv.osv):
    _name="mark.marksheet"
    _description="Report Card"
    _columns={
         "dob":fields.date('Date of Birth',required=True),
        'age_text':fields.text('textage'),
    }

def onchange_getage_id(self,cr,uid,ids,dob,context=None):
    current_date=datetime.now()
    current_year=current_date.year
    birth_date = parser.parse(dob)
    current_age=current_year-birth_date.year
     val = {
        'age_text':current_age
    }
    return {'value': val}

Hi Folks,

I try the above code to calculate age, and making some modifcation. It inherit hr.employee modul in hr folder here are my modification:

in python add the import

from openerp.osv import osv,fields
from datetime import datetime
import dateutil.parser
class hr_employee(osv.osv):
     _inherit = 'hr.employee'

    def hitung(self, dob):
        current_date=datetime.now()
        current_year=current_date.year
        birth_date = dateutil.parser.parse(dob)
        current_age=current_year-birth_date.year
        return current_age
 
    def _calc_age(self, cr, uid,ids, field, arg, context=None):
        results = {}
        employee = self.browse(cr, uid, ids, context=context)
        if employee.dob:
            results[employee.id] = self.hitung(employee.dob)
        return results
 
    _columns = {
        'dob'         : fields.date('Date Of Birth'),
        'age_text'    : fields.function(_calc_age, type='char', string="Age"),
    }
    _defaults = {,
        'dob': fields.date.context_today,
    }

    def onchange_getage_id(self,cr,uid,ids,dob,context=None):
        current_date=datetime.now()
        current_year=current_date.year
        birth_date = dateutil.parser.parse(dob)
        current_age=current_year-birth_date.year
        val = {
            'age_text':current_age
        }
        return {'value': val}  

<field name="dob" on_change="onchange_getage_id(dob,context)"/>
<field name="age_text"/>

i am getting an error while defining in this line : val = { 'age_text':current_age } Is this correct ??
