calculating age base on date of birth using @api onchange()

from openerp import fields, models, api, _
from dateutil.relativedelta import relativedelta
from datetime import date

class students(models.Model): 
    _name = 'school.student'

    dob = fields.Date('DOB')
    age = fields.Char('Age')


    @api.onchange('dob')
    def set_age(self):
        for rec in self:
	    if rec.dob:
	    dt = rec.dob
	    d1 = datetime.strptime(dt, "%Y-%m-%d").date()
            d2 = date.today()
	    rd = relativedelta(d2, d1)
            rec.age = str(rd.years) + ' years'

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}

mark_marksheet()

Xml View Code

<record id="view_mrk_form" model="ir.ui.view">
    <field name="name">mark.marksheet.form</field>
        <field name="model">mark.marksheet</field>
        <field name="arch" type="xml">
        <form string="Score Card">
            <field name="dob" on_change="onchange_getage_id(dob,context)"/>
            <field name="age_text"/>
        </form>
    </field>
</record>

from datetime import datetime, timedelta

class StudentStudent(models.Model):
    _name = 'student.student'

student_dob = fields.Date(string="Date of Birth")
calc_age = fields.Integer(string="Calculated Age", compute="age_calc", store=True)

# Calculated age

from odoo import models, fields, api



class resume(models.Model):

    _name = 'resume.resume'


    date_of_birth = fields.Date(string="Date Of Birth")

    age = fields.Integer(compute="age_calc", store=True)


    @api.depends('date_of_birth')

    def age_calc(self):

        if self.date_of_birth is not False:

            self.age = (datetime.today().date() - datetime.strptime(self.date_of_birth, '%Y-%m-%d').date()) // timedelta(days=365)

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}  

in xml add these:
<field name="dob" on_change="onchange_getage_id(dob,context)"/>
<field name="age_text"/>
