Hi, I think you are correct with your pseudocode - you can do a Model.objects.filter(unique_code==random_code).count() - and then loop on that. It should work. The reason why I thought you should use the signals is because thats how I have done the same things in the past. However, you can just

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

Generating a unique 10 digit ID for each model instance

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
