Can I remove ORDER BY from a Django ORM query?

Question

It seems like Django by default adds ORDER BY to queries. Can I clear it?

from slowstagram.models import InstagramMedia
print InstagramMedia.objects.filter().query

SELECT
  `slowstagram_instagrammedia`.`id`,
  `slowstagram_instagrammedia`.`user_id`, 
  `slowstagram_instagrammedia`.`image_url`,
  `slowstagram_instagrammedia`.`video_url`,  
  `slowstagram_instagrammedia`.`created_time`,  
  `slowstagram_instagrammedia`.`caption`, 
  `slowstagram_instagrammedia`.`filter`, 
  `slowstagram_instagrammedia`.`link`, 
  `slowstagram_instagrammedia`.`attribution_id`, 
  `slowstagram_instagrammedia`.`likes_count`, 
  `slowstagram_instagrammedia`.`type`
FROM
  `slowstagram_instagrammedia`
ORDER BY
  `slowstagram_instagrammedia`.`id`
ASC

```

Answer 1

Actually, just do a query.order_by() is enough.

Here is the implementation of order_by, for your reference -

def order_by(self, *field_names):
    """
    Returns a new QuerySet instance with the ordering changed.
    """
    assert self.query.can_filter(), \
        "Cannot reorder a query once a slice has been taken."
    obj = self._clone()
    obj.query.clear_ordering(force_empty=False)
    obj.query.add_ordering(*field_names)
    return obj

Answer 2

You can use: clear_ordering method from query

"""Removes any ordering settings. 

If 'force_empty' is True, there will be no ordering in the resulting
query (not even the model's default).
"""

Example:

>>> from products.models import Product
>>> products = Product.objects.filter(shortdesc='falda').order_by('id')
>>> print products.query
SELECT "products_product"."id", "products_product"."shortdesc"
WHERE "products_product"."shortdesc" = falda
ORDER BY "products_product"."id" ASC
>>> products.query.clear_ordering()
>>> print products.query
SELECT "products_product"."id", "products_product"."shortdesc"
WHERE "products_product"."shortdesc" = falda

Answer 3

Try to use .order_by('?') at the end of queryset.
