[QUESTION] What is the difference between pk and id?

[msr8]

Like take a post for example. It has two unique values, pk and id, whats the difference?

[vapefy]

media_id - String ID "{media_id}_{user_id}", e.g. "2277033926878261772_1903424587"
media_pk - Integer ID (real media id), e.g. 2277033926878261772

Ohhh okay, and what's the matter with a user's pk and id?

[vapefy]

there is no different i guess. User has no id, just a pk. ik some arguments of functions names contains user_id, but it is the same. someone correct me if i'm wrong.

What is the media_id ever used for? Are there expected collisions in media_pk?
