Question

I know we can require that the SlugField be unique with unique=True option, but is it possible to require it to be unique only for a particular user, so two different user could have the same SlugField but a user cannot have two identical slugField?

models. py:

from django.db import models
from django.contrib.auth.models import User

class ezApp(models.Model):
    name = models.SlugField(max_length=50, unique=True )
    date_created = models.DateTimeField('date created')
    date_updated = models.DateTimeField('date updated')
    created_by = models.ForeignKey(User)
    in_use = models.BooleanField()

Answer 1

You’ll want to use unique_together as detailed here:
https://docs.djangoproject.com/en/dev/ref/models/options/#unique-together

class MyModel(models.Model):
    # ...

    class Meta:
        unique_together = ('name', 'created_by')

You’ll have to do some babysitting at the form level too, so the user gets usable error messages when they try to add duplicate names.
