django Rest框架离线文档

Django Rest框架是一个强大且灵活的工具，用于构建基于Python的Web API。它提供了许多功能，使开发人员能够轻松地创建和管理RESTful API。本文将介绍Django Rest框架的一些主要特性，并通过一个案例代码来展示其用法。

python
# serializers.py
from rest_framework import serializers
from .models import Student
class StudentSerializer(serializers.ModelSerializer):
    class Meta:
        model = Student
        fields = ['id', 'name', 'age', 'grade']
# views.py
from rest_framework import viewsets
from .models import Student
from .serializers import StudentSerializer
class StudentViewSet(viewsets.ModelViewSet):
    queryset = Student.objects.all()
    serializer_class = StudentSerializer
# urls.py
from django.urls import path, include
from rest_framework.routers import DefaultRouter
from .views import StudentViewSet
router = DefaultRouter()
router.register(r'students', StudentViewSet)
urlpatterns = [
    path('', include(router.urls)),
]
