python - How can I create custom page for django admin?

Question

I want to create custom page for admin panel without model. For first i copy index.html to project folder:

mysite/
    templates/
        admin/
            index.html

Then add to apps block my code:

<div class="module">
    <table summary="{% blocktrans with name="preferences" %}Models available in the preferences application.{% endblocktrans %}">
        <caption><a href="preferences" class="section">{% blocktrans with name="preferences" %}Preferences{% endblocktrans %}</a></caption>
            <tr>
                <th scope="row"><a href="preferences">Preferences</a></th>
                <td><a href="preferences" class="changelink">{% trans 'Change' %}</a></td>
            </tr>
    </table>
</div>

This works good, then I create new page /templates/admin/preferences/preferences.html and add to urls.py:

url(r'^admin/preferences/$', TemplateView.as_view(template_name='admin/preferences/preferences.html')),

And add code to preferences.html:

{% extends "admin/base_site.html" %}
{% block title %}Test page{% endblock %}

Run it and see message with error "The requested admin page does not exist.". What I do wrong?

Answer 1

You need to add your admin URL before the URL patterns of the admin itself:

urlpatterns = patterns('',
   url(r'^admin/preferences/$', TemplateView.as_view(template_name='admin/preferences/preferences.html')),
   url(r'^admin/', include('django.contrib.admin.urls')),
)

This way the URL won't be processed by Django's admin.
