This is a function wrapping the code from example from django docs.

The required parameters are: request which is a Request object from a view, and objects - a list of objects to paginate.

You may want to tune number of items per page by specifying count and the name of a GET parameter through param_name

To use it in your view just wrap the paginated object into a function for example:

def someview(request):
    articles = Article.objects.all()
    ... some other logics ...
    return render_to_response(template, {'articles': paginate(request, articles)}
