I don't know how robust or secure this is, but it's working for me so far.

Usage:

{% load tracwiki %}

{{ object.body|tracwiki }}

from trac.test import EnvironmentStub, Mock, MockPerm 
from trac.mimeview import Context 
from trac.wiki.formatter import HtmlFormatter 
from trac.web.href import Href

from django.utils.safestring import mark_safe
from django import template

@register.filter

    return mark_safe(HtmlFormatter(env, context, s).generate())

It fails to use the [Image()] macro. But for works flawlessy rendering text

failed to render a wiki link like

[wiki:DoSomeThing do some thing]

change the next line to correct this

context = Context.from_request(req, id='wiki')

or simply remove the parameter:

context = Context.from_request(req)

tested at Trac version 0.12.1

I will see more about the resource parameter to find how improve these wiki links
