passing request in django template tag

Question

I tried to access the request in my custom template tag function. But it is not working.

views.py

def candidate(request):
   .......
   .......
   return render(request, template, context)

templatetags

@register.simple_tag(takes_context=True)
def make_url(context, doc_url):
    request = context["request"]
    protocol = "https://" if request.is_secure() else "http://"
    host = request.get_host()
    new_url = "%s%s%s" %(protocol, host, doc_url)
    return new_url

template.html

<iframe src="{{  candidate.resume_file.url | make_url }}" frameborder="0"></iframe>

Django filters aren't given any special access to the context from which they are called, they're just plain old functions.

You'll need to pass in anything you want to use within the function.
