Any thoughts on A/B testing in Django based project? [closed]

Answer 1

A code based on the one by Justin Voss:

def ab_test(force = None):
    def _ab_test(view):
        def wrapped_view(request, *args, **kwargs):
            request, template_name, cont = view(request, *args, **kwargs)
            if 'ui' in request.GET:
                request.session['ui'] = request.GET['ui']
            if 'ui' in request.session:
                cont['ui'] = request.session['ui']
            else:
                if force is None:
                    cont['ui'] = '0'
                else:
                    return redirect_to(request, force)
            return direct_to_template(request, template_name, extra_context = cont)
        return wrapped_view
    return _ab_test

example function using the code:

@ab_test()
def index1(request):
    return (request,'website/index.html', locals())

@ab_test('?ui=33')
def index2(request):
    return (request,'website/index.html', locals())

What happens here: 1. The passed UI parameter is stored in the session variable 2. The same template loads every time, but a context variable {{ui}} stores the UI id (you can use it to modify the template) 3. If user enters the page without ?ui=xx then in case of index2 he's redirected to '?ui=33', in case of index1 the UI variable is set to 0.

I use 3 to redirect from the main page to Google Website Optimizer which in turn redirects back to the main page with a proper ?ui parameter.
