I am using a multipart/form-data in a form which have a manytomany relation as well as multiple file upload. But the validated data doesn't contains the array data
Views.py
class ExpenseCreateAPIView(CreateAPIView):
permission_classes = (permissions.IsAuthenticated,)
parser_classes = ( MultiPartParser,)
def post(self, request, *args, **kwargs):
owner = request.user.pk
d = request.data.copy()
d['owner'] = owner
serializer = ExpenseSerializer(data=d)
print("exp")
if serializer.is_valid():
serializer.save()
return Response(serializer.data, status=status.HTTP_201_CREATED)
return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
Serializers.py
class ExpenseSerializer(serializers.ModelSerializer):
transactions = ExpenseTransactionsSerializer(many=True, required=False)
bill = ExpenseFilesSerializer(many=True, required=False)
class Meta:
model = Expense
fields = "__all__"
def create(self, validated_data):
print("validated data", validated_data)
items_objects = validated_data.pop('transactions', None)
files_objects = validated_data.pop('bill', None)
prdcts = []
files = []
for item in items_objects:
i = ExpenseTransactions.objects.create(**item)
prdcts.append(i)
if files_objects == None:
pass
else:
for item in files_objects:
i = ExpenseFiles.objects.create(**item)
files.append(i)
instance = Expense.objects.create(**validated_data)
instance.transactions.set(prdcts)
instance.bill.set(files)
return instance
How else should I use the MultiPartParser class in the views ?
I keep getting the error:
TypeError: 'NoneType' object is not iterable
at
for item in items_objects:
