django sort descending

To sort a queryset in Django in descending order, you can use the order_by() method along with the - (minus) sign before the field name. Here are the steps to achieve this:

1. Start by importing the model you want to query. For example, if you have a model called "MyModel", you would import it like this:

from myapp.models import MyModel

1. Next, define your queryset by calling the objects attribute on your model. For example:

queryset = MyModel.objects.all()

1. To sort the queryset in descending order, use the order_by() method and prefix the field name with a minus sign. For example, if you want to sort by the "name" field in descending order, you would write:

queryset = queryset.order_by('-name')

1. Optionally, you can chain multiple fields to perform a multi-level sort. For example, if you also want to sort by the "date" field in descending order, you would write:

queryset = queryset.order_by('-name', '-date')

1. Finally, you can iterate over the sorted queryset to access the sorted results. For example:

for item in queryset:
    # Access item attributes or perform desired operations

By following these steps, you can sort a queryset in Django in descending order using the order_by() method with the minus sign (-) before the field name.
