在面板管理员中激活和停用注释无法正常工作

Question

在通过选中活动框向模板上的用户显示评论来激活评论之后，一切似乎都很好，但是在再次取消激活该评论后，它将创建一个新实例，或者用另一个单词将面板中的评论复制为活动，就像在取消选中活动框后复制评论一样。 我正在使用Postgresql数据库，是否可能这个问题来自数据库？

models.py

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=False)

    class Meta:
        ordering = ('created',)

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

forms.py

class CommentForm(forms.ModelForm):
    class Meta:
        model = Comment
        fields = ('name', 'email', 'body')

views.py

def post_detail(request, year, month, day, post):
    post = get_object_or_404(Post, slug=post,
                             status='published',
                             publish__year=year,
                             publish__month=month,
                             publish__day=day)
    # List of active comments for this post
    comments = post.comments.filter(active=True)

    new_comment = None

    if request.method == 'POST':
        # A comment was posted
        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/post/detail.html', {'post': post, 'comments': comments,
                                                     'new_comment': new_comment,
                                                     'comment_form': comment_form})

admin.py

@admin.register(Comment)
class CommentAdmin(admin.ModelAdmin):
    list_display = ('name', 'email', 'post', 'created', 'active')
    list_filter = ('active', 'created', 'updated')
    search_fields = ('name', 'email', 'body')

您可以看到here此评论重复。

更新：
