How to add a comment without going to another page?

Question

Django

Hello, there is a form for adding reviews, but I don’t know how to display it under the product. I only did so that you could follow the link and fill out a review on another page.
Product reviews:

{% for comment in product.comments.all %}

                                        <div class="col-md-12 ">

                                            <strong class="comments">{{ comment.user }}</strong>
                                            <div class="time">
                                                Опубликованно: {{ comment.created|date:"G:i | d-m-Y " }}
                                            </div>
                                            <h4 class="imeno_comment">Отзыв: {{ comment.comment }}</h4>

                                            {% if comment.image %}
                                                <img src="{{ comment.image.url }}" class="otziv_img" alt=""/>

                                            {% endif %}
                                            <hr>
                                        </div>
                                    {% empty %}
                                        <p>Пока нет отзывов :(</p>
                                    {% endfor %}
                                    {% if user.is_active %}
                                        <div class="btn-pos">
                                            <label class="hvr-skew-backward ">
                                                <a class="add_comment"
                                                   href="{% url 'products:add_comment' slug=product.slug %}">Добавить
                                                    отзыв</a>
                                            </label>
                                        </div>
                                    {% else %}
                                        <h4 align="center">Авторизуйтесь, чтобы оставить отзыв</h4>
                                    {% endif %}
