Ошибка as_view() в urls.py Django

Пытаюсь добавить возможно редактирования таблицы, но выдает ошибку:

Generic detail view GroupUpdateView must be called with either an object pk or a slug in the URLconf.

HTML code:

{% extends 'main/doki.html' %}
{% load static %}

{% block content %}

    <div class="groupcont">
            <div class="disian-camp">
                <a href="{% url 'create2' %}"><li><button class="btn btn-info"><i class "fas fa-plus-circle"><i> Добавить новую таблицу</button></li></a>
                    <table class="disian-campe">
                        <thead>
                            <tr>
                                <th>id</th>
                                <th>Номер группы</th>
                                <th>ФИО Куратора</th>
                                <th>Редактирование</th>
                                <th>Удаление</th>
                            </tr>
                        </thead>
                        <tbody>
                            {% for el in groups %}
                                <tr>
                                    <td>{{ el.titleid }}</td>
                                    <td>{{ el.titlegroup1 }}</td>
                                    <td>{{ el.titlecurator }}</td>
                                    <td><a href="{% url 'create2' %}">Редактировать</a></td>
                                    <td><a href="">Удалить</a></td>
                                </tr>
                            {% endfor %}
                        </tbody>
                    </table>
            </div>


{% endblock %}

second HTML code:

{% extends 'main/doki.html' %}
{% load static %}

{% block title %} Страница добавления таблиц {% endblock %}

{% block content %}
    <div class="createtable2">
        <style>
        form {
            margin-left: 32%;
            width: 500px;
            text-align: center;
        }
        </style>
            <form method="post">
                {% csrf_token %}
                {{ form.titleid }} <br>
                {{ form.titlegroup1 }} <br>
                {{ form.titlecurator }} <br>
                <button class "btn btn-success" type="submit">Добавить таблицу</button>
