django queryset last 10
To retrieve the last 10 objects from a Django queryset, you can follow these steps:
Start by importing the model you want to query. For example, if you want to query a model called "MyModel", you would write:
python from myapp.models import MyModel
Then, use the
objects
attribute of the model to access the queryset manager. This allows you to perform queries on the model. For example:python my_queryset = MyModel.objects
Next, you can use the
order_by()
method to specify the ordering of the queryset. To retrieve the last 10 objects, you would typically order the queryset in descending order based on a field that represents the order. For example, if you have a field called "created_at" that represents the creation time of the objects, you would write:python my_queryset = my_queryset.order_by('-created_at')
Finally, you can use the
[:10]
slicing notation to retrieve the last 10 objects from the ordered queryset. This will return a list-like object containing the desired objects. For example:python last_10_objects = my_queryset[:10]
By following these steps, you can retrieve the last 10 objects from a Django queryset.
