I came across this issue calling the following and FK fields with _id are
ignored:
serialize('json', ...., fields=['title', 'state_id']).
State is a ForeignKey on my queryset. I can perform fields=['title',
'state'] and I get serialization correctly of {'state': int}. However, if I
specify fields=['state_id'] then the serialization completely ignores that
field. It would be nice if we could serialize foreign keys on either
field.name or field.attname.
I wrote a hack to make it work myself but it breaks the non-id use case.
def start_serialization(self):
for field in [x for x in self.selected_fields if '_id' in x]:
self.selected_fields.append(field.replace('_id', ''))
super().start_serialization()
def handle_fk_field(self, obj, field):
if not self.use_natural_foreign_keys and not hasattr
(field.remote_field.model, "natural_key"):
self._current[field.attname] = getattr(obj, field.attname)
else:
return super().handle_fk_field(obj, field)
