I have a social article website; I created a content type named Article. When a user creates an article, I want to generate a code shown to the user. This code should be saved in the database because users can return to this article with this code. It's important to build a views with this code.
I think I must create a CCK field, generate a code (for example hash the node ID or the timestamp of when the node has been create), and show this code in disable a text box for the author.
Is there any module to do this? What other alternatives do I have?
