How to put relational table name in .py files?

Question

When I change '_' for '.'  an error appears.
model name in *pgAdmin: irco_festivos_res_partner_rel*

@api.onchange('delegacion')
def onchange_delegacion(self):
_logger.info(self.env[*'irco.festivos.res.partner.rel*'].search([]))

Error:
KeyError: 'irco.festivos.res.partner.rel'

Info · Answer

Odoo uses MVC with Model first technique, so you have to create model in python file and add this file in __init__.py file.
While you install this module, database table will be created automatically with the declared fileds. in pyhthon file if you have mentioned model name with '.' it will be replaced with '_' in database automatically.
But if you have mentioned model name with '_' in python file then it will remain as it is, it won'y be changed to '.'
