Django | Set the defulat ordering rule for queries in the models

Though we can specify order explicitly in queries like below

Posts.objects.order_by('published')

it is repetitive and most of the times we will want to order by a particular field.

We can specify the order in the models like this

class Post(models.Model):
    title = models.CharField(max_length=140)
    content = models.TextField()
    published = models.DateTimeField()

    def __unicode__(self):
        return self.title

    class Meta:
        ordering = ['published']
