Natural sort on Django Queryset

Question

I am working on a system that lists out a range of products sorted by their product code. The product codes are made up of two letters for the followed by a number, for exam

Answer 1

Try this

def alphanumeric_sort(objects_list, sort_key):
    """ Sort a list of objects by a given key
    This function sort a list of objects by a given
    key common across the objects
    Sorting can be implemented on keys that are either
    alphabets, integers or both
    """
    convert = lambda text: int(text) if text.isdigit() else text
    alphanum_key = lambda key: [
        convert(c) for c in re.split("([0-9]+)", getattr(key, sort_key))
    ]
    return sorted(objects_list, key=alphanum_key)
