orm - Django queries - id vs pk

Question

When writing django queries one can use both id/pk as query parameters.

Object.objects.get(id=1)
Object.objects.get(pk=1)

I know that pk stands for Primary Key and is just a shortcut, according to django's documentation. However it is not clear when one should be using id or pk.

Answer 1

It doesn't matter. pk is more independent from the actual primary key field i.e. you don't need to care whether the primary key field is called id or object_id or whatever.

It also provides more consistency if you have models with different primary key fields.
