Hi there!
I was wondering if it's possibile to add some kind of option to specify a custom JSON encoder in AutoResponseView view.
I'm using this package https://github.com/nshafer/django-hashid-field and if I don't specify the specific JSON encoder while I'm using ModelSelect2Widget widget, it will throw an Object of type Hashid is not JSON serializable error.
Here the AutoResponseView that works:
from django.core import signing
from django.core.signing import BadSignature
from django.core.serializers.json import DjangoJSONEncoder
from django.http import Http404, JsonResponse
from django.views.generic.list import BaseListView
from hashid_field.hashid import Hashid # from the package [https://github.com/nshafer/django-hashid-field](https://github.com/nshafer/django-hashid-field)
from .cache import cache
from .conf import settings
# custom JSON encoder
class HashidJSONEncoder(DjangoJSONEncoder):
def default(self, o):
if isinstance(o, Hashid):
return str(o)
return super().default(o)
class AutoResponseView(BaseListView):
def get(self, request, *args, **kwargs):
self.widget = self.get_widget_or_404()
self.term = kwargs.get("term", request.GET.get("term", ""))
self.object_list = self.get_queryset()
context = self.get_context_data()
return JsonResponse(
{
"results": [
{"text": self.widget.label_from_instance(obj), "id": obj.pk}
for obj in context["object_list"]
],
"more": context["page_obj"].has_next(),
},
encoder=HashidJSONEncoder # using custom JSON encoder
)Thanks a lot!
