Hi everyone,
I am new to Odoo development and need to know what is the difference between @api.model and @api.multi and if possible, also tell me when/where to use each of them?
Thank you in advance
Regards
Paulo

Hi,
@api.multi :-
Self will be the current RecordSet without iteration. It is the default behavior:
@api.multi
def afun(self):
len(self)
@api.model:-
This decorator will convert old API calls to decorated function to new API signature. It allows to be polite when migrating code.
@api.model def afun(self): pass
Please see this link: https://odoo-new-api-guide-line.readthedocs.io/en/latest/decorator.html
Thanks
Great. Thank you very much @Cybrosys
@api.multi :-
The decorator in default for methods from new api onwards, which the self contains a recordset. So operations should be done by iterating through the recordsets if it is a set.
eg:
@api.multi
def multi_method(self):
""" """
print self # [model(1,2,3,4)] or [model(1,)]
@api.model :-
The decorator used on methods where the contents are not relevant. No ids will get passed with such methods.
eg:
@api.model
def create(self, vals)
""" """
print self # recordset with no id
Great. Thank you very much @Hilar
