如何根据用户配置文件过滤帖子？- Django

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

class UserProfile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    interests = models.CharField(max_length=100)
    keywords = models.CharField(max_length=100)
    # 其他字段根据需要添加

from django.db.models.signals import post_save
from django.dispatch import receiver

@receiver(post_save, sender=User)
def create_user_profile(sender, instance, created, **kwargs):
    if created:
        UserProfile.objects.create(user=instance)

@receiver(post_save, sender=User)
def save_user_profile(sender, instance, **kwargs):
    instance.userprofile.save()

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

    def is_filtered(self, user_profile):
        # 根据用户配置文件中的过滤条件进行过滤
        if self.author.username in user_profile.keywords:
            return True
        if self.title in user_profile.keywords:
            return True
        # 其他过滤条件根据需要添加
        return False

from django.contrib.auth.decorators import login_required

@login_required
def filtered_posts(request):
    user_profile = request.user.userprofile
    posts = Post.objects.all()
    filtered_posts = [post for post in posts if not post.is_filtered(user_profile)]
    # 返回过滤后的帖子给前端展示
    return render(request, 'filtered_posts.html', {'posts': filtered_posts})
