Wrapper-function Pattern
This is an example how to create a wrapping function that can read all incoming arguments, do something with them and then call the original function. This pattern works well with generic views. Note that wrapper function accepts arguments in both ways: as a list of unnamed arguments and as a list of keyword-value pairs. A real-world example: def published_object_list(request, *args, **kwargs): arg_names = object_list.func_code.co_varnames params = dict(zip(arg_names, args)) params.update(kwargs) params['queryset'] = params['queryset'].filter(is_published=True) if request.is_ajax(): params['template_name'] = "ajax/" + params['template_name'] return object_list(request, **params)
