Django provides a MultipleObjectsReturned exception as an attribute of\neach model class to identify the class of object for which multiple objects\nwere found, allowing you to catch exceptions for a particular model class.\nThe exception is a subclass of\ndjango.core.exceptions.MultipleObjectsReturned.
objectsLink to this heading#Each non-abstract Model class must have a\nManager instance added to it.\nDjango ensures that in your model class you have at least a\ndefault Manager specified. If you don’t add your own Manager,\nDjango will add an attribute objects containing default\nManager instance. If you add your own\nManager instance attribute, the default one does\nnot appear.
