✅

It looks like you should use a foreign key instead of the one-to-one field as it’s a one-to-many relationship (user can write many articles):

class Post(models.Model):
    user = models.ForeignKey(User)
    title = models.CharField(max_length=255)
    content = models.TextField()
    date = models.DateField(auto_now_add = True)

    def __unicode__(self):
         return self.title
