Adapt a view if an app is installed with Django

Question

I have a web app with a project that works alone (it's index, login.. pages).

I would need to change the index page if a new app is installed (e.g: add a link, a table in the template with my app models..). Have it dynamic.

The removal of the app must let the project intact and just remove the link.

How can I do that? Is it possible?

Answer 1

def my_view(request):
    from django.conf import settings
    app_installed = 'app_name' in settings.INSTALLED_APPS

    return render_to_response(template_name, {'app_installed': app_installed})

template:

{% if app_installed %}
    ...
{% endif %}
