Not that there is anything wrong with this, I would have made a simple
tag that simply returns the content - it means you don't have to write
a tedious tag parsing function, or a node class:
from urllib2 import urlopen
from django.utils.safestring import mark_safe
from django.conf import settings
@register.simple_tag
def get_asset_contents(path):
uri = "%s%s" % (settings.ASSET_SERVER_LOCATION, path)
return mark_safe(urlopen(uri).read())
{% get_asset_contents "/path/to/asset.html" %}
Cheers
