urlpatterns = [
    url(r\'^historia-clinica/(?P[W\\d\\-]+)/$\', ClinicH         


        

Answer 1

There is a bug ticket on Django regarding this issue however a custom so called 'complex encoder' by python docs can help you.

import json
from uuid import UUID


class UUIDEncoder(json.JSONEncoder):
    def default(self, obj):
        if isinstance(obj, UUID):
            # if the obj is uuid, we simply return the value of uuid
            return obj.hex
        return json.JSONEncoder.default(self, obj)

Now if we did something like this

json.dumps(my_object, cls=UUIDEncoder)

Your uuid field should be encoded.
