如何在Django Admin中解决帖子和用户的评论链接

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)
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    content = models.TextField()

from django.contrib import admin
from .models import Post, Comment

admin.site.register(Post)
admin.site.register(Comment)

from django.contrib import admin
from .models import Post, Comment

class PostAdmin(admin.ModelAdmin):
    list_display = ('title', 'display_comments')

    def display_comments(self, obj):
        comments = obj.comment_set.all()
        return ', '.join([comment.content for comment in comments])

admin.site.register(Post, PostAdmin)
admin.site.register(Comment)
