How to test your django model using shell

Question

I am trying to learn Django and have a very simple question that I am not able to get around with. I have coded my Django model as:

class Work(models.Model):
    STATES = (
        ('STARTED', 'started'),
        ('IN_PROGRESS', 'running'),
        ('FINISHED', 'completed'),
        ('ERROR', 'Error'),
    )
    owner = models.ForeignKey("auth.User")
    temp  = models.CharField(max_length=50, null=True, blank=True)
    current_run = models.CharField(max_length=50, null=True, blank=True)
    completion_percentage = models.IntegerField(blank=True, null=True)
    status = models.CharField(choices=STATES, max_length=50, blank=True, null=True)

I have regenerated the db and now I want to use it Django views. But, before that is there a way to test it using python manage.py shell?

I am trying to do:

d_ = Work.objects.create(owner='admin')

I get the error

ValueError: Cannot assign "'admin'": "Work.owner" must be a "User" instance.

Currently, I have userid as 'admin' in Users. I have tried doing few things to get around the error but I keep getting some kind of error because of the owner field (which is set to foreign key of auth.User).

Any help will be appreciated here. Thank you!

What's confusing you about that message? You need an actual User instance, not a username. — Daniel Roseman, Jul 06 '17 at 19:34
@DanielRoseman you're right. I tried user instance but i was doing something wrong. Now, I get it and below answer also helps me. Thanks! — yguw, Jul 06 '17 at 19:49

You need to use an actual user object. Try this

from django.contrib.auth.models import User
admin = User.objects.get(username='admin')
d_ = Work.objects.create(owner=admin)
