Have you seen this happen?

An employee who never ordinarily talks to HR or Accounting walks in to the office for “a quick question about buying options.” The HR person then explains the process, the costs involved and so forth.

Say goodbye to your co-worker because in the next few weeks that the employee is preparing to leave for greener pastures.

My goal is to conditionally include google analytics tracking on my Django templates depending on whether settings.DEBUG is on or off as defined in my settings.py file. To accomplish you can write a template context processor that returns the variable with the request context which will make the variable values readable in your Django Templates.

First, add a context_processors.py to the folder for your app (my app is called auto)

Next, copy and paste the function into context_processors.py. As you can see we are simply stuffing the settings variable onto the request object.

def debug_mode(request):
    from django.conf import settings
    return {'debug_mode': settings.DEBUG}

Now, we add our context processor to the TEMPLATE_CONTEXT_PROCESSORS section in settings.py. If you do not have this section, add it. It won’t break anything.

TEMPLATE_CONTEXT_PROCESSORS = (
    'auto.context_processors.debug_mode',
)

Next we have to use the RequestContext. Add this import statement to views.py.

from django.template import RequestContext

Now, set context_instance for all of your template render calls.

def detail(request, template_name="myview.html"):
    return render_to_response(template_name, context, context_instance=RequestContext(request))

Finally, you can see if settings.DEBUG is True or False in your Django Templates!

{% if debug_mode %}
<h1>We are debugging!</h1>
{% endif %}
