Re: Generating a unique 10 digit ID for each model instance

The database usually handles this and you don't need to worry, there are many corner cases and DB systems are able to handle them

But they won't look like whatever format you would like, usually it is just a number

Why do you need the IDs to look like that?

Let's say I have a model called 'Dogs'.  Users can create instances of Dogs.  For every Dogs instance that is created, I want to assign a globally unique ID to it.  The ID will be 3 capitalized letters followed by 7 numbers.  E.g. ABC1234567, POZ2930193

What is the easiest way to go about doing this?  I looked into UUID but it generates a longer string.  Keep in mind that the ID must be globally unique - so after one has been created, it should not be created again.

Thanks.
