Django - 如何将 Page 对象转换为 Json

如何解决Django - 如何将 Page 对象转换为 Json

我有这个用于学习目的的社交网络项目，我正在尝试为其添加分页功能。在将它们转换为 JSON 后，我设法使用 JavaScript 成功呈现页面中的所有帖子。问题是我收到此错误：Object of type Page is not JSON serializable 当我尝试像这样对帖子进行分页时：

all_posts = Post.objects.all().order_by("-timestamp").all()
serialized_posts = [post.serialize() for post in all_posts]
paginator = Paginator(serialized_posts,10) #every page displays up to 10 post

page_obj = paginator.get_page(pagenumber)
return JsonResponse(page_obj,safe=False)

这是 Post 模型：

class Post(models.Model):
    autor = models.ForeignKey(User,on_delete=models.CASCADE,null=True,blank=True,default="",related_name="user_post")
    content = models.TextField(max_length=240)
    likers = models.ManyToManyField(User,related_name="posts_liked")
    timestamp = models.DateTimeField(auto_Now_add=True)
    def serialize(self):
        return {
            "id": self.id,"autor": self.autor.username,"content": self.content,"likers": [user.username for user in self.likers.all()],"timestamp": self.timestamp.strftime("%b. %d,%Y,%H:%M %p"),"autor_profile_pic": self.autor.profile_picture
        }

关于如何解决这个问题有什么想法吗？

解决方法

先分页，后序列化

def all_posts(request,pagenumber):
    all_posts = Post.objects.all().order_by("-timestamp").all()
    paginator = Paginator(all_posts,10)
    page_obj =  paginator.get_page(pagenumber)
    serialized_posts = [post.serialize() for post in page_obj]
    return JsonResponse(serialized_posts,safe=False)
