如何将两个模型应用于一个视图？

# models.py
from django.db import models

class Post(models.Model):
    title = models.CharField(max_length=100)
    content = models.TextField()

class Comment(models.Model):
    post = models.ForeignKey(Post, on_delete=models.CASCADE)
    content = models.CharField(max_length=200)

# views.py
from django.shortcuts import render
from .models import Post, Comment

def post_detail(request, post_id):
    post = Post.objects.get(pk=post_id)
    comments = Comment.objects.filter(post=post)
    context = {
        'post': post,
        'comments': comments
    }
    return render(request, 'post_detail.html', context)

# post_detail.html
<h1>{{ post.title }}</h1>
<p>{{ post.content }}</p>

<h2>Comments:</h2>
<ul>
  {% for comment in comments %}
    <li>{{ comment.content }}</li>
  {% empty %}
    <li>No comments yet.</li>
  {% endfor %}
</ul>
