AttributeError while using Django Rest Framework with serializers

Question

I am following a tutorial located here that uses Django Rest Framework, and I keep getting a weird error about a field.

I have the following model in my models.py<

Answer 1

The problem here is that you are trying to convert a Queryset(list) of entries into a single entry. The solution is something along these lines.

from rest_framework import serializers

class TaskListSerializer(serializers.ListSerializer):
    child = TaskSerializer()
    allow_null = True
    many = True

Then

if request.method == 'GET':
        tasks = Task.objects.all()
        serializer = TaskListSerializer(tasks)
        return Response(serializer.data)
