Question

How can I detect, from views or template file, if my admin user is logged in or not? For example, use case for my site:

1. User opens /admin/, enter correct credentials
2. Then user open some page, for example /page/ and there are “Add” and “Delete” buttons
3. User opens /admin/ and click “Log out”
4. /page/ -> there are no “Add” and “Delete” buttons

Django version 1.4

Joseph’s answer is fine for your simple case, but in reality neither is_staff nor is_superuser is a perfect fit. Assuming your page is, say, /polls/ (a list of Poll objects, in an app called poll), you should test the specific poll.change_poll and poll.delete_poll permissions.

In a template:

{% for poll in polls %}
    {% if perms.poll.change_poll %}<a href='/polls/edit/{{ poll.id }}'>Edit</a>{% endif %}
    {% if perms.poll.delete_poll %}<a href='/polls/delete/{{ poll.id }}'>Delete</a>{% endif %}
{% endfor %}

Or in a view using has_perm:

if not request.user.has_perm('poll.change_poll'):
    return HttpResponseForbidden('Nope!')

Or in a view using a decorator:

@permission_required('poll.change_poll')
def edit_poll(request, poll_id):
    # ....

You can assign these permissions directly to a user, to a group (and then put a user in that group) or by setting is_superuser.
