How do I output HTML in a message in the new Django messages framework?

Question

I\'m trying to display a bit of html in a message that\'s being displayed via the new Django messages framework. Specifically, I\'m doing this via the ModelAdmin.message_use

You can use format_html. It applies escaping to all arguments.

For example, if we can link with a 'mymodel' detail using an attribute call 'name':

from django.contrib import messages
from django.utils.html import format_html


message = format_html("{} {}",
                      "This is the mymodel", 
                      reverse('myapp:mymodel-detail', args=(mymodel.id,)),
                      mymodel.name)
messages.info(request, message)
