Not that I know of. If what you want to do is update a specific field on
the M2O (let's say a Char field),
you could add a Function(Char) field which would present the M2O field, and
define a setter
that will update it :
class MyModel:
my_m2o = fields.M2O(...)
my_m2o_name = fields.Function(fields.Char(...),
'on_change_with_my_m2o_name', 'set_my_m2o_name')
@fields.depends('my_m2o')
def on_change_with_my_m2o_name(self, name=None):
return self.my_m2o.name
@classmethod
def set_my_m2o_name(cls, instances, name, value):
cls.write([x.my_m2o for x in instances], {'name': value})
