如何在Django中显示类别列表中的帖子列表

from django.db import models

class Category(models.Model):
    name = models.CharField(max_length=100)

    def __str__(self):
        return self.name

class Post(models.Model):
    title = models.CharField(max_length=100)
    content = models.TextField()
    category = models.ForeignKey(Category, on_delete=models.CASCADE)

    def __str__(self):
        return self.title

from django.shortcuts import render
from .models import Category, Post

def category_list(request):
    categories = Category.objects.all()
    posts = Post.objects.all()
    context = {
        'categories': categories,
        'posts': posts
    }
    return render(request, 'category_list.html', context)

{% for category in categories %}
    <h2>{{ category.name }}</h2>
    <ul>
        {% for post in posts %}
            {% if post.category == category %}
                <li>{{ post.title }}</li>
            {% endif %}
        {% endfor %}
    </ul>
{% endfor %}

from django.urls import path
from .views import category_list

urlpatterns = [
    path('categories/', category_list, name='category_list'),
]
