当您在模板中循环 kwalificaties 时，您将循环命名为 variable/instance i，您需要在标签中使用此名称或将 i 更改为 kwalificatie

{% for i in kwalificaties %}

                       <tr>
                           <td>{{i.naam}}</td>
                           <td>{{i.ehbo}}</td>
                           <td>{{i.treinen}}</td>
                           <td>{{i.extra}}</td>
                           <td><a class="btn btn-sm btn-outline-secondary" href="{% url 'updatekwalificatie' i.id %}">Update</a></td>
                           <td><input type="submit" value="Verwijder"></td>
                       </tr>

                       {% endfor %}
