How to call a function every interval time Odoo 11 - python-3.x

Question

i know we can create automatic action using cron in odoo
but I want something a different
in the mass mailing of odoo i want to add a repetion option of mail mass mailings
Example in the Form view_mail_mass_mailing_form > Options page
I added a repetition selection field,
I added this because I want each mass mail alone
class MailMassMailing(models.Model):
_inherit = 'mail.mass_mailing'
recurrence_mail = fields.Selection([
('daily', 'Day'),
('weekly', 'Weeks'),
('monthly', 'Months'),
], string='Recurring')
I want this mass mailng to send each (days or weeks or months)
how to call a function with interval date,
how to call a function every (days or weeks or months)
The sending of this mass mailing is revived from the date of creation

Answer 1

Just extend Mass Mailing model with a new date field and implement a model method to use for a daily running ir.cron.
from odoo import api, fields, models
class MailMassMailing(models.Model):
_inherit = 'mail.mass_mailing'
recurrence_mail = fields.Selection([
('daily', 'Day'),
('weekly', 'Weeks'),
('monthly', 'Months'),
], string='Recurring')
last_sent_on = fields.Date()
#api.model
def run_send_recurring(self):
""" Resend mass mailing with recurring interval"""
domain = [('recurrence_mail', '!=', False)]
# TODO monthly should be solved in another way, but that
# is not needed for this example
deltas = {'daily': 1, 'weekly': 7, 'monthly': 30}
today = fields.Date.today()
for mass_mail in self.search(domain):
# never sent? go send it
if not mass_mail.last_sent_on:
# send the way you want
# or get delta between today and last_sent_on
last_dt = fields.Date.from_string(mass_mail.last_sent_on)
if (today - last_dt).days >= deltas[mass_mail.recurrence_mail]:
# send the way you want

Thank you #CZoellner for your help
I found the solution with your idea
# Solution ############### .py
#api.model
def run_send_recurring(self):
""" Resend mass mailing with recurring interval"""
date_format = '%Y-%m-%d'
domain = [('recurrence_mail', '!=', False),('state','=','done')]
deltas = {'daily': 1, 'weekly': 7, 'monthly': 30}
logger.info("______deltas________: %s ",deltas)
today = fields.Date.today()
logger.info("______today________: %s ",today)
for mass_mail in self.search(domain):
logger.info("______mass_mail________: %s ",mass_mail)
# never sent? go send it
if not mass_mail.last_sent_on:
self.put_in_queue()
joining_date = mass_mail.last_sent_on
current_date = (datetime.today()).strftime(date_format)
print('joining_date',joining_date)
d1 = datetime.strptime(joining_date, date_format).date()
logger.info("______1 day________: %s ",d1)
d2 = datetime.strptime(current_date, date_format).date()
logger.info("______2 day________: %s ",d2)
logger.info("______deltas[mass_mail.recurrence_mail]________: %s ",deltas[mass_mail.recurrence_mail])
r = relativedelta(d1,d2)
logger.info("______r day________: %s ",r.days)
if (r ,'>=' , deltas[mass_mail.recurrence_mail]):
mass_mail.put_in_queue()
