[Answered ]-Wagtail admin interface on django project

See http://docs.wagtail.io/en/v1.11.1/getting_started/integrating_into_django.html for details of integrating Wagtail into an existing project – in particular, note the “URL configuration” section, which explains how to make the Wagtail admin backend available at the URL /admin/ or any other URL of your choosing.

Wagtail is not intended to be a drop-in replacement for the Django admin – you will have to re-implement the configuration logic to actually make your models visible within Wagtail. The ModelAdmin module is the closest equivalent to Django admin: http://docs.wagtail.io/en/v1.11.1/reference/contrib/modeladmin/index.html
