Why not do both. I've always preferred letting the database generate an auto primary key (id in django) even if my usage is primarily a different column for key. Storing an int isn't wasting much space, what do you have to lose? I've got a users object for example that requires a unique email

A point that I missed was the speed. Is method 1) maybe faster than method 2? I think it could.. because in 1) there are only numbers stored as primary_key and not strings (which can be as long as 255 characters). Speed is one thing.. but is there any other difference between the two methods?

You can use fixtures. In your application folder, create a "fixtures" folder and in that folder create a "initial_data.json" file. Populate it like this: [ { "pk": 1, "model": "application.Contact", "fields": { "name": "Vincent" } } ] And when you run syncdb, the data
