How to store form data in database?

Question

Django

I do by analogy with adding comments, nothing happens. Where is the mistake?

index.html

<form method="post" action="{% url 'create_order' %}">
                                            {% csrf_token %}
                      <div class="row">
                        <div class="form-group col-lg-6 col-md-6 col-sm-12">
                                                    <label>Ваше имя</label>
                                                    <input type="text" name="phoneNumber" placeholder="Ваше имя" required>
                                                </div>
                                                <div class="form-group col-lg-6 col-md-6 col-sm-12">
                                                    <label>Ваш телефон</label>
                                                    <input type="text" name="phoneNumber" placeholder="Номер телеофна" required>
