Methods that return a ``QuerySet`` such as ``Manager.get_query_set`` or
``ModelAdmin.queryset`` have been renamed to ``get_queryset``.
If you are writing a library that implements, for example, a
``Manager.get_query_set`` method, and you need to support old Django versions,
you should rename the method and conditionally add an alias with the old name::
class CustomManager(models.Manager):
def get_queryset(self):
pass # ...
if django.VERSION < (1, 6):
get_query_set = get_queryset
# For Django >= 1.6, models.Manager provides a get_query_set fallback
# that emits a warning when used.
If you are writing a library that needs to call the ``get_queryset`` method and
must support old Django versions, you should write::
method = getattr(some_manager, 'get_queryset', some_manager.get_query_set)
method(params)
``shortcut`` view and URLconf
