How do i edit/delete data from the frontend in Django with Elasticsearch?

I would like to retrieve data from my backend (postgresql) to the frontend so i can edit/delete it.

Note: My project is using django_elasticsearch_dsl_drf

I have implemented this in views.py:

def update(request, id):
    resp = Response.objects.get(pk = id)
    resp.response = request.POST.get('Response')
    resp.save()
    return render(request, 'app/update', {
    })

urls.py:

url(r'update/(\d+)/$', views.update, name="update")

How would i display it in my forms?

update.html:

<table class="dataTable">

{% for field in qform.visible_fields %}
    <tr>
        <th>{{ field.label_tag }}*</th>
        <td>{{ field }}</td>
    </tr>
{% endfor %}
    <tr>
        <th>{{ rform.Response.label_tag }}*</th>
        <td>{{ rform.Response }}</td>
    </tr>
    <tr>
        <th>{{ rform.Topic.label_tag }}*</th>
        <td>{{ rform.Topic }}</td>
    </tr>
    <tr>
        <th>{{ rform.Client.label_tag }}*</th>
        <td>{{ rform.Client }}</td>
    </tr>
    <tr>
        <th>{{ rform.Planit_location.label_tag }}*</th>
        <td>{{ rform.Planit_location }}</td>
    </tr>
    <tr>
        <th>{{ rform.Date_added.label_tag }}</th>
        <td>{{ rform.Date_added }}</td>
    </tr>
    <tr>
        <th>{{ rform.Document.label_tag }}</th>
        <td>{{ rform.Document }}</td>
    </tr>

Also I am getting an Assertion error "No exception message supplied" when i try to access the url .../update

EDIT StackTrace:

Your url path should be:

url(r'update/(?P<id>\d+)/$', views.update, name="update")

Also, you need to return something from your update method:

   return render(request, 'update_add.html', { 'rform': resp })
