[ODOO]:Override private method of another class

Question

I want to change the _create_invoice() method in sale.advance.payment.inv model.

This method is called from another method of the same class create_invoices()

I was tried to inherit the method. But have success only with create_invoices()

So in result, I want to know why I can't change _create_method() (i know they called private method's but the way of inheriting must be the same I think)

Code:

#original Odoo class
class SaleAdvancePaymentInv(models.TransientModel):
    _name="sale.advance.payment.inv"
    ...
    @api.multi
    def create_invoices(self):
        ...
        self._create_invoice(order, so_line, amount)

    @api.multi
    def _create_invoice(self, order, so_line, amount):
        ...

And here is the code, how i tried to inherit methods:

class myClass(models.TransientModel):
    _inherit="sale.advance.payment.inv"

    #INHERITING create_invoices() **SUCCESS INHERITED**
    @api.multi
    def create_invoices(self):
        _logger.debug("PRINT TRUE IF INHERIT IS SUCCESS")
        #HERE ODOO PRINT THE MESSAGE SUCCESS.
        ...
        self._create_invoice(order, so_line, amount)#HERE I TRY TO CALL THE METHOD WHICH I WAS CREATED FOR INHERITING
        _logger.debug("Print OK if all OK")
        #HERE ODOO IS NOT PRINT ANYTHING
        res = super(myClass, self).create_invoices()
        return res

    #HERE I TRY TO INHERIT THE ORIGINAL _create_invoice() method
    @api.multi
    def _create_invoice(self, order, so_line, amount):
        _logger.debug("PRINT TRUE IF SUCCESS INHERITED")
        #IN DEBUG LOGS ODOO DIDN'T PRINTED ANYTHING HERE

So it's look like after i call _create_invoice() in my inherited method, odoo from that point start to use the code from original class and not from myClass().

any help will be appreciated

Your inheritance is already fine, but you should try change _logger.debug(.. for _logger.info( to see your logs, I got this messages from my log console the other mode start the Odoo server in DEBUG mode:

2018-07-04 07:17:34,612 13072 INFO mydatabase odoo.addons.mymodule.models.sale: PRINT TRUE IF INHERIT IS SUCCESS

2018-07-04 07:19:03,848 13072 INFO mydatabase odoo.addons.mymodule.models.sale: PRINT TRUE IF SUCCESS INHERITED

I hope this answer can be helpful for you.
