Python flask实现delete键删除评论用什么方法，pythonflask,后台从数据库查询出可能要

后台从数据库查询出可能要删除的评论后，前端/后端如何控制一个delete键只删除其对应的评论，而不影响其他评论？（使用db.session.delete(),db.session.commit())
后台查询评论部分代码：

comments = Comment.query.all()lists=[]if form.validate_on_submit():        keywords = form.content.data        for comment in comments:            if keywords in comment.body:                #comp   = form.completed.data                comment_body = comment.body                com = Comment.query.filter_by(body=comment_body).first()                postid = com.post_id                posts = Post.query.filter_by(post_id=postid).first()                titles = posts.title                lists.append(dict(comment_body = comment.body, postid = com.post_id, titles = posts.title))        return render_template('comment_search.htm',form=form,commentss=lists)
