make primary key with 2 fields in Django?

Question

I want to make a primary key from 2 fields in Django.

Fields are below

- current Time 
- userId

How Can I do

Answer 1

If the key has to be single-column:

id is added "out-of-the-box" (variable.id) and for current time just add

from django.db import models

date = models.DateTimeField( auto_now_add=True)

in yourapp/models.py

so you have your 2 values, out of witch you can make your key in any shape you want.

if you want multi-column-key then read the other answer. Hope to help you.
