[Answered ]-Access Users Model foreign Key

class Device(model.Model):
    deviceID = model.CharField(MaxLength=10)
    owner = model.ForeignKey(User)

• You should check the standarts for coding styles Django Coding Style Standarization

  • Use singular words for classes
  • Begin class name with capital letter
  • Begin class field with non capital letter
  • etc…

• You should also check oficial documentation Django: Foreign Key

After a model is related to another via ForeignKey you can do following actions, If you have a Device object in a variable called dev:

dev.owner  # This return an User object, so you can access all user fields
dev.owner.username
dev.owner.email

To access Django’s in-built User model, you need to import this:

 from django.contrib.auth.models import User

Assuming you have imported models:

from django.db import models

NOTE: it’s models instead of model. This typo also exists in Liarez’s answer.
