如何在Django中获取具有ManyToManyFiled关系的关联模型的上下文数据

from django.db import models

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

class Article(models.Model):
    title = models.CharField(max_length=100)
    tags = models.ManyToManyField(Tag)

from django.shortcuts import render
from .models import Article

def article_detail(request, article_id):
    article = Article.objects.get(id=article_id)
    tags = article.tags.all()
    context = {
        'article': article,
        'tags': tags,
    }
    return render(request, 'article_detail.html', context)

<h1>{{ article.title }}</h1>
<ul>
    {% for tag in tags %}
        <li>{{ tag.name }}</li>
    {% endfor %}
</ul>
