Django REST框架：在ModelViewSet中保存相关模型

使用Django REST框架的ModelViewSet可以轻松地保存相关模型，并实现强大的API功能。ModelViewSet是Django REST框架提供的一个视图集，它集成了常见的CRUD操作（创建、读取、更新、删除）以及其他一些常用的API功能，如分页、搜索和过滤等。通过使用ModelViewSet，我们可以更快速、高效地构建出符合RESTful风格的API。

python
from django.db import models
class Author(models.Model):
    name = models.CharField(max_length=100)
    email = models.EmailField()
    def __str__(self):
        return self.name
class Book(models.Model):
    title = models.CharField(max_length=100)
    author = models.ForeignKey(Author, on_delete=models.CASCADE)
    def __str__(self):
        return self.title

python
from rest_framework import viewsets
from .models import Book, Author
from .serializers import BookSerializer, AuthorSerializer
class BookViewSet(viewsets.ModelViewSet):
    queryset = Book.objects.all()
    serializer_class = BookSerializer
class AuthorViewSet(viewsets.ModelViewSet):
    queryset = Author.objects.all()
    serializer_class = AuthorSerializer

python
from django.urls import include, path
from rest_framework.routers import DefaultRouter
from .views import BookViewSet, AuthorViewSet
router = DefaultRouter()
router.register(r'books', BookViewSet)
router.register(r'authors', AuthorViewSet)
urlpatterns = [
    path('', include(router.urls)),
]

POST /authors/
{
    "name": "John Smith",
    "email": "john@example.com"
}

POST /books/
{
    "title": "Introduction to Django",
    "author": 
}
