How can I use order_by in Django querysets?

How can I use order_by in Django querysets?

You can use the order_by() method to sort your querysets. For example, MyModel.objects.all().order_by('field_name') will sort the results by 'field_name'.

Can I order by multiple fields?

Yes, you can order by multiple fields by passing them as arguments. For example: MyModel.objects.all().order_by('field1', '-field2').

What does the '-' before a field mean?

The '-' indicates descending order. So -field2 will sort the results in descending order based on 'field2'.

Are there any other sorting options?

You can also use distinct() with order_by() to remove duplicates after sorting, or use annotate() for more complex queries.
