Django common dictionary available to templates

We need to leverage TEMPLATE_CONTEXT_PROCESSORS, the following example uses the “home” application

1. add this to settings.py

   TEMPLATE_CONTEXT_PROCESSORS = ("django.contrib.auth.context_processors.auth", "django.core.context_processors.debug", "django.core.context_processors.i18n", "django.core.context_processors.media", "django.core.context_processors.static", "django.contrib.messages.context_processors.messages", "home.context_processor.remote_ip")

2. in home application, create a python file called context_processor.py
3. in the context_processor.py add a function like this:

   def remote_ip(request):
   return {'remote_ip': request.META['REMOTE_ADDR']}

4. for any templates needs to use this processor need to render the template like this

   vars = {}
   
   return render_to_response('home.html', vars, context_instance=RequestContext(request))
   

5. use it in the templates like {{ remote_ip }}
