如何在Django中获取特定的查询集

from django.db import models

class Book(models.Model):
    title = models.CharField(max_length=100)
    author = models.CharField(max_length=50)
    publication_date = models.DateField()
    # 其他字段...

class BookManager(models.Manager):
    def get_recent_books(self):
        # 获取最近出版的5本图书
        return self.order_by('-publication_date')[:5]

class Book(models.Model):
    title = models.CharField(max_length=100)
    author = models.CharField(max_length=50)
    publication_date = models.DateField()
    objects = models.Manager()  # 默认的模型管理器
    recent_books = BookManager()  # 自定义的模型管理器
    # 其他字段...

from django.shortcuts import render
from .models import Book

def recent_books_view(request):
    recent_books = Book.recent_books.get_recent_books()
    return render(request, 'books/recent_books.html', {'books': recent_books})
