Order By
To sort QuerySets, Django uses the order_by() method:
Example
mydata = Member.objects.all().order_by('firstname').values()
In SQL, the above statement would be written like this:
SELECT * FROM members ORDER BY firstname;
Descending Order
By default, the result is sorted ascending (the lowest value first), to change the direction to descending (the highest value first), use the minus sign (NOT), - in front of the field name:
Example
mydata = Member.objects.all().order_by('-firstname').values()
In SQL, the above statement would be written like this:
SELECT * FROM members ORDER BY firstname DESC;
Multiple Order Bys
To order by more than one field, separate the fieldnames with a comma in the order_by() method:
Example
mydata = Member.objects.all().order_by('lastname', '-id').values()
In SQL, the above statement would be written like this:
SELECT * FROM members ORDER BY lastname ASC, id DESC;
