如何使用外键将帖子添加到django用户模型

from django.db import models
from django.contrib.auth.models import User

class Post(models.Model):
    title = models.CharField(max_length=100)
    content = models.TextField()
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    created_at = models.DateTimeField(auto_now_add=True)

python manage.py makemigrations
python manage.py migrate

from django.shortcuts import render, get_object_or_404
from .models import Post

def create_post(request):
    if request.method == 'POST':
        title = request.POST['title']
        content = request.POST['content']
        author = request.user
        post = Post.objects.create(title=title, content=content, author=author)
        return redirect('post_detail', post_id=post.id)
    return render(request, 'create_post.html')

def post_detail(request, post_id):
    post = get_object_or_404(Post, id=post_id)
    return render(request, 'post_detail.html', {'post': post})
