Python '；反向单描述符'；对象没有属性'；过滤器'；

“ReverseMayToneDescriptor”对象没有属性“filter” 为什么？
我正试图用django创建一个博客，在添加评论和分类时遇到了问题 我犯了一个错误

views.py 

    from django.shortcuts import render, 
    get_object_or_404
    from .models import Post, Comment
    from django.views import generic
    from django.http import HttpResponse
    from .forms import CommentForm
    def blog_list(request):
    post = Post.objects.all().order_by('-date')
    return render(request,'blog/blog_list.html', {'posts':post})
    def blog_detail(request, slug):
    #return HttpResponse(slug)
    detail_post = Post.objects.get(slug=slug)
    comments = Post.comments.filter(active=True)
    new_comment = None
    # Comment posted
    if request.method == 'POST':
        comment_form = CommentForm(data=request.POST)
        if comment_form.is_valid():

            # Create Comment object but don't save to database yet
            new_comment = comment_form.save(commit=False)
            # Assign the current post to the comment
            new_comment.post = post
            # Save the comment to the database
            new_comment.save()
    else:
        comment_form = CommentForm()
    return render(request,'blog/blog_detail.html', {'detail_post':detail_post, 'comments':comments, 'new_comment': new_comment, 'comment_form': comment_form})

我希望有人能帮我解决添加类别的问题

14.comments = Post.comments.filter(active=True) …

▶ 局部变量

这是我的
models.py

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

   

    class Post(models.Model):
       title = models.CharField(max_length=100)
       slug = models.SlugField()
       body = models.TextField()
       date = models.DateTimeField(auto_now_add=True)
    first_src = models.CharField('первоисточник', blank=True, max_length=100)
    author = models.ForeignKey(User, on_delete= models.CASCADE )
    thumb = models.ImageField(default='default.png', blank=True)

    # add AND GO TO MIGRATE AND MAKEMIGRATIONS !!!

    class Meta:
        ordering = ['-date']


    def __str__(self):
        return self.title

    def snippet(self):
        return self.body[:50]+'...'

    """def get_absolute_url(self):
        from django.urls import reverse
        return reverse("post_detail", kwargs={"slug": str(self.slug)})"""


    class Comment(models.Model):
    post = models.ForeignKey(Post,
                             on_delete=models.CASCADE,
                             related_name='comments')
    name = models.CharField(max_length=80)
    email = models.EmailField()
    body = models.TextField()
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)
    active = models.BooleanField(default=True)

    class Meta:
        ordering = ('created',)

    def __str__(self):
        return 'Comment by {} on {}'.format(self.name, self.post) 

怎么了

我希望有人能帮我解决添加类别的问题

14.comments = Post.comments.filter(active=True) …

您试图在类（

Post

）上进行筛选，但希望在特定模型（

detail\u Post

）上进行筛选：

comments=detail\u post.comments.filter（active=True）

是的，谢谢，就这样）
