Ok this got a bit long so I summarize and I added the corrections that were
made along the way:
1) I have two classes Party and Patient
2) The only constraint to create a Patient is to have a related Party
3)I need to create a Patient when a Party is created and set the relation
between the two
(Actually when updating and deleting too and it has to work both ways but
I'm focusing just on this for now)
here are the two classes:
class Patient(ModelSQL, ModelView):
__name__ = 'gnuhealth.patient'
name = fields.Many2One(
'party.party', 'Patient', required=True,
domain=[
('is_patient', '=', True),
('is_person', '=', True),
],
states={'readonly': Bool(Eval('name'))},
help="Person associated to this patient")
class Party(ModelSQL, ModelView):
'Party'
__name__ = 'party.party'
@classmethod
def create(cls, vlist):
records = super(Party, cls).create(vlist)
pool = Pool()
Patient = pool.get('gnuhealth.patient')
patient = Patient()
patient.name = records
patient.save()
return records
when I try to create a party I get:
Traceback (most recent call last):
File
"/gnuhealth/tryton/server/trytond-3.2.4/trytond/protocols/dispatcher.py",
line 158, in dispatch
result = rpc.result(meth(*c_args, **c_kwargs))
File
"/gnuhealth/tryton/server/trytond-3.2.4/trytond/modules/custom/custom.py",

line 80, in __set__
assert isinstance(value, (Target, NoneType))
AssertionError
a representation of "records" which would be "value" in the last line of
the stack trace gives me:
[Pool().get('party.party')(17809)]
other thing I tried is not saving Patient and appending it to records:
@classmethod
def create(cls, vlist):
records = super(CustomParty, cls).create(vlist)
pool = Pool()
Patient = pool.get('gnuhealth.patient')
patient = Patient()
records.append(patient)
return records
which gives me:
Traceback (most recent call last):
