Your template tag has access to any variable defined in the template
context (that is anything you pass from your view).

So, for example if you passed it from your view as "tag_model":

(note that is completely untested).

Another way to do it would be to write your template tag to accept an
argument which is the model you are after (as a string), and use
"django.db.models.get_model" to get the model.

Send variable from view function to a templatetag

[alecs]

How can I send variable from my view function(which renders my
template) to a template tag library(which is {% load blah %} in this
template? I want to make my tag cloud independent from model:

register = Library()

@register.inclusion_tag("tags/cloud.html")
def tag_cloud(request):
"""Takes model and tag from context and returns cloud as a
response."""
tag_list = Tag.objects.cloud_for_model(HARD_CODED_MODEL, steps=9,
distribution =
tagging.utils.LOGARITHMIC,filters={'removed':False})
return {'tags' : tag_list}

Thanks :)
