CLARIFICATION: here is the actual class:
class CustomParty(ModelSQL, ModelView):
'Party'
__name__ = 'party.party'
@classmethod
def create(cls, vlist):
records = super(CustomParty, cls).create(vlist)
target = CustomPatient()
target.name = records[0]
target.save()
but this gives me
assert self.name is not None
AssertionError
printing records[0]
gives me <class 'trytond.pool.party.party'>
the question would be how do I get the instances of the party that was just
created? I have the impression that I'm missing some basic python stuff
here, even some basic programming concept maybe.. sorry about that.
