Get class name for empty queryset in django

Get class name for empty queryset in django

In Django, when you execute a query on a model's manager and it returns an empty queryset, you can use the model_name attribute to get the class name of the model associated with that queryset. Here's how you can do it:

from myapp.models import MyModel # Replace with your actual model import # Create an empty queryset empty_queryset = MyModel.objects.none() # Get the class name of the model associated with the empty queryset class_name = empty_queryset.model._meta.model_name # Print the class name print(class_name)

In the code above, replace myapp.models with the actual import path to your model, and replace MyModel with the name of your model. The empty_queryset.model attribute gives you access to the model associated with the queryset, and _meta.model_name retrieves the model's name in lowercase.
