Как сделать лайки на Flask?

Question

У меня есть новостной сайт на flask, и я хочу сделать систему лайков в нём, но не знаю как.

Вот мой код:

@bp.route('/article/<int:id>', methods=['GET', 'POST'])
def article(id):
    comment_form = CommentsCreateForm()
    like_form = LikesAndDislikes()
    article = db.session.query(Articles).filter(Articles.id == id).first()
    creator = db.session.query(User).filter(User.id == article.creator).first()
    comments = db.session.query(Comment).filter(Comment.article_id == id).all()  # список кометариев
    if comment_form.validate_on_submit():
        comment = Comment()
        comment.comment_creator = current_user.id
        comment.article_id = id
        comment.content = comment_form.text.data

        current_user.comment.append(comment)
        db.session.commit()
        return render_template("news_template.html", article=article, creator=creator, comments=comments,
                               form=comment_form)
    return render_template("news_template.html", article=article, creator=creator, comments=comments, form=comment_form)

Форма для создания комментария

class CommentsCreateForm(FlaskForm):
    text = StringField('Введите коментарий', validators=[DataRequired()])
    submit = SubmitField('Отправить')

{% extends "base.html" %}

{% block content %}

<div class="card text-center">
    <img src="/static/img/{{article.image}}">
    <div class="card-body text-left">
        <h5 class="card-title">{{ article.title }}</h5>
        <p class="card-text">{{article.content}}</p>
        <p>Автор: {{creator.username}}</p>

    <div class="card-footer text-left">

    {% endfor %}
</div>
