Django queries - id vs pk

Question

Hi all,

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.

Thanks!

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

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