我正在关注位于的教程here https://godjango.com/41-start-your-api-django-rest-framework-part-1/使用Django 休息框架 http://www.django-rest-framework.org/，并且我不断收到有关字段的奇怪错误。
我的模型中有以下模型models.py
from django.db import models
class Task(models.Model):
completed = models.BooleanField(default=False)
title = models.CharField(max_length=100)
description = models.TextField()
然后我的序列化器在serializers.py
from rest_framework import serializers
from task.models import Task
class TaskSerializer(serializers.ModelSerializer):
class Meta:
model = Task
fields = ('title', 'description', 'completed')
and my views.py如下：
from rest_framework import status
from rest_framework.decorators import api_view
from rest_framework.response import Response
from task.models import Task
from api.serializers import TaskSerializer
@api_view(['GET', 'POST'])
def task_list(request):
"""
List all tasks, or create a new task
"""
if request.method == 'GET':
tasks = Task.objects.all()
serializer = TaskSerializer(tasks)
return Response(serializer.data)
elif request.method == 'POST':
serializer = TaskSerializer(data=request.DATA)
if serializer.is_valid():
serializer.save()
return Response(serializer.data, status=status.HTTP_201_CREATED)
else:
return Response(
serializer.errors, status=status.HTTP_400_BAD_REQUEST
)
我的 urls.py 有这一行：
url(r'^tasks/$', 'task_list', name='task_list'),
当我尝试访问时curl http://localhost:9000/api/tasks/，我不断收到以下错误，但我不知道该怎么办：
AttributeError at /api/tasks/
Got AttributeError when attempting to get a value for field `title` on serializer `TaskSerializer`.
The serializer field might be named incorrectly and not match any attribute or key on the `QuerySet` instance.
Original exception text was: 'QuerySet' object has no attribute 'title'.
我缺少什么？
