Question

I’m using Django 1.3 and I have a simple_tag that I need to return some un-escaped HTML and no matter what I do it’s still escaping my & to & and my | to %7C.

from django import template
from django.template import loader, Context
from django.utils.safestring import mark_safe

register = template.Library()

@register.simple_tag()
def show_stuff(arg1=None, arg2=None, arg3='someconstant'):

    # Do some stuff

    if someconstant == 'somevalue':
        template_name = 'template1.html'
    else:
        template_name = 'template2.html'

    template = loader.get_template(template_name)
    html = template.render(Context( {'myvar': myvar,} ))
    html = mark_safe(html)
    print type(html)
    return html

The print statement reveals

<class 'django.utils.safestring.SafeUnicode'>

which from my understanding isn’t supposed to be escaped. I’m calling the tag in my template like so:

{% show_stuff 'arg1' 'arg2' 'arg3' %}

Help would be greatly appreciated.

Update: Tried the following from comments below. Didn’t return an error, but still escapes the HTML:

    ...
    template = loader.get_template(template_name)
    html = template.render(Context( {'myvar': myvar,} ))
    html = mark_safe(html)
    print type(html)
    return html
show_stuff().is_safe=True

Also tried wrapping the contents of template1.html and template2.html in

{% autoescape off %}
template html contents with & and |
{% endautoescape %}

and wrapping the templatetag call itself with autoescape tags. No success.

In discussion with the author of the question we found that the characters were not actually escaped. Scoopseven (the author) viewed the source html with the option “Show Selection Source” of a context menu in Firefox. In this case escaped characters are shown.
