Solve the following python programming problem given the following code:
def cached_view_fab(_cached) : 
    def force_render(response) : 
        if (hasattr (response, 'render') and callable (response.render)) : 
            response.render () 
return response 
def cached_view(* dargs, **dkwargs) : 
        def decorator(func) : 
            dkwargs ['key_func'] = view_cache_key 
            cached_func = _cached (* dargs, ** dkwargs) (compose (force_render, func)) 
            @ wraps (func) 
            def wrapper(request, * args, **kwargs) : 
                assert isinstance (request, HttpRequest), 'A view should be passed with HttpRequest as first argument' 
                if (request.method not in ('GET', 'HEAD')) : 
                    return func (request, * args, ** kwargs) 
return cached_func (request, * args, ** kwargs) 
if hasattr (cached_func, 'invalidate') : 
                wrapper.invalidate = cached_func.invalidate 
                wrapper.key = cached_func.key 
return wrapper 
return decorator 
return _cached
