I am trying to implement a RESTful web service. Everything was going well until I tried to deserialize a list with objects from a post request. My code is this:
#serializers.py
class ResultSerializer(serializers.ModelSerializer):
class Meta:
model=test_result
fields=('id', 'label')
#views.py
class results(APIView):
"""
Post the results for a test set.
"""
permission_classes = (permissions.IsAuthenticated,)
def post(self, request, pk, format=None):
ser=ResultSerializer(data=request.DATA)
for i in range(len(ser.data)):
if ser.data[i].is_valid():
entry=test_result(user=User.objects.get(username=request.user.username), test_id=Detail.objects.get(test_id=pk), id=Article.objects.get(id=ser.data[i]['id']), label=ser.data[i]['label'])
entry.save() #I use a test_result table in my database to save things
return Response(ser.data[i], status=status.HTTP_201_CREATED)
return Response(ser.errors, status=status.HTTP_400_BAD_REQUEST)
The curl command i use to test is:
curl -v -H "Accept: application/json" -H "Content-type: application/json" --user plao:1234 -X POST -d '[{"id":23401853, "label":1504}, {"id":23401853, "label":1505}]' http://127.0.0.1:8000/tests/uploadResults/1/
I have tested my code (without the indexes) with simple post and it works fine. But when I try to post a list I can't.
However, after trying the code in the shell (python manage.py shell
) I noticed that there is a TODO in the code of the framework:
# TODO: error data when deserializing lists
Is there a problem with the code? Is there any advise I can use? In the final version the users will post strings like the following one, but I try to reach it step by step:
{"documents": [{"id":[Label1,...,LabelN]},....,{"id":[Label1,..,LabelM]}]}
If I can handle lists I will be able to hanble that kind of json.
