Django sets this for you if your database supports it (ie: you are using postgres or mysql with innodb tables). If you are using mysql, check that tables aren't MyISAM. If you want to do this inside Django, more complex because if you change an object's primary key, Django concludes that you want to work with another row altogether and doesn't modify your original row.
Can I ask why you would need to change PKs?
