class Post(models.Model):
    """
    Stores a single blog post entry related to :model:`auth.User`.
    """

    title = models.CharField(max_length=200, unique=True)
    slug = models.SlugField(max_length=200, unique=True)
    author = models.ForeignKey(User, on_delete=models.CASCADE, related_name='blog_posts')
    content = models.TextField()
    created_on = models.DateTimeField(auto_now_add=True)
    updated_on = models.DateTimeField(auto_now=True)
    status = models.IntegerField(choices=STATUS, default=0)
    excerpt = models.CharField(max_length=200, blank=True)
