如何在django模板上呈现具有多对多关系的字段

from django.db import models

class Book(models.Model):
    title = models.CharField(max_length=100)
    authors = models.ManyToManyField('Author')

class Author(models.Model):
    name = models.CharField(max_length=50)

from django.shortcuts import render
from .models import Book

def book_list(request):
    books = Book.objects.all()
    return render(request, 'book_list.html', {'books': books})

<!-- book_list.html -->
{% for book in books %}
    <h2>{{ book.title }}</h2>
    <ul>
        {% for author in book.authors.all %}
            <li>{{ author.name }}</li>
        {% endfor %}
    </ul>
{% endfor %}
