How to get the response in true JSON?

[jerinpetergeorge]

How can I transform the below Customer instance into a JSON?

unit = Unit(settings.UNIT_API_DOMAIN, settings.UNIT_API_KEY)
customer = unit.customers.get("2331163")


json.dumps(customer) # TypeError: Object of type UnitResponse is not JSON serializable

I was expecting some sort of utility functions that convert the entire object (by traversing through the whole object) to a JSON

I think the main issue is that the CustomerDTOs are not inheriting from UnitDTO (that has the to_dict() method). What we do to get just JSON is (this is using Django, so you should be able to customize the base encoder as you wish):

from django.core.serializers.json import DjangoJSONEncoder
from unit.models import UnitDTO


class UnitJSONEncoder(DjangoJSONEncoder):
    def default(self, o):
        try:
            if issubclass(o.__class__, UnitDTO):
                return o.to_dict()
            return super().default(o)
        except TypeError:
            return o.__dict__

json.loads(json.dumps(unit_object, cls=UnitJSONEncoder))

This should get you the JSON object.

P.S: The DjangoJSONEncoder

class DjangoJSONEncoder(json.JSONEncoder):
    """
    JSONEncoder subclass that knows how to encode date/time, decimal types, and
    UUIDs.
    """

    def default(self, o):
        # See "Date Time String Format" in the ECMA-262 specification.
        if isinstance(o, datetime.datetime):
            r = o.isoformat()
            if o.microsecond:
                r = r[:23] + r[26:]
            if r.endswith("+00:00"):
                r = r[:-6] + "Z"
            return r
        elif isinstance(o, datetime.date):
            return o.isoformat()
        elif isinstance(o, datetime.time):
            if is_aware(o):
                raise ValueError("JSON can't represent timezone-aware times.")
            r = o.isoformat()
            if o.microsecond:
                r = r[:12]
            return r
        elif isinstance(o, datetime.timedelta):
            return duration_iso_string(o)
        elif isinstance(o, (decimal.Decimal, uuid.UUID, Promise)):
            return str(o)
        else:
            return super().default(o)
