Let's say that you have one addon that does basically what you want it to do. However, what it does when it inherits another class should be tweaked. For instance, account/account_invoice.py has:
class mail_compose_message(models.Model):
_inherit = 'mail.compose.message'
@api.multi
def send_mail(self):
context = self._context
if context.get('default_model') == 'account.invoice' and \
context.get('default_res_id') and context.get('mark_invoice_as_sent'):
invoice = self.env['account.invoice'].browse(context['default_res_id'])
invoice = invoice.with_context(mail_post_autofollow=True)
invoice.write({'sent': True})
invoice.message_post(body=_("Invoice sent"))
return super(mail_compose_message, self).send_mail()
If I inherit mail_compose_message and update something, say set 'sent' to False, the account_invoice code runs afterwards and sets it back to True.
In this example, how do I inherit send_mail() method AFTER the code above is run to set sent or mail_post_autofollow to False?
