在Django中成功发布链接到Poll's API中的问题的选择可以通过以下步骤完成:
例如,以下是一个可能的实现示例:
# models.py
from django.db import models
class Poll(models.Model):
question = models.CharField(max_length=200)
class Choice(models.Model):
poll = models.ForeignKey(Poll, on_delete=models.CASCADE)
choice_text = models.CharField(max_length=200)
# serializers.py
from rest_framework import serializers
from .models import Poll, Choice
class ChoiceSerializer(serializers.ModelSerializer):
class Meta:
model = Choice
fields = ['id', 'choice_text']
class PollSerializer(serializers.ModelSerializer):
choices = ChoiceSerializer(many=True, read_only=True)
class Meta:
model = Poll
fields = ['id', 'question', 'choices']
# views.py
from rest_framework.generics import GenericAPIView
from .models import Poll
from .serializers import PollSerializer
class PollAPIView(GenericAPIView):
serializer_class = PollSerializer
def get(self, request, poll_id):
poll = Poll.objects.get(id=poll_id)
serializer = self.get_serializer(poll)
return Response(serializer.data)
# urls.py
from django.urls import path
from .views import PollAPIView
urlpatterns = [
path('polls/<int:poll_id>/', PollAPIView.as_view()),
]
通过访问/polls/<poll_id>/
这个URL,你可以获取特定Poll对象及其关联的问题选项。这个示例中使用了DRF的序列化器和通用视图,以及Django的URL路由来实现API的发布和链接。对于更复杂的需求,你可能需要进一步进行配置和定制化。
