~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. versionadded:: 2.0
You can use a dash as the fixture name to load input from ``sys.stdin``. For
example::
django-admin loaddata --format=json -
When reading from ``stdin``, the :option:`--format <loaddata --format>` option
is required to specify the :ref:`serialization format <serialization-formats>`
of the input (e.g., ``json`` or ``xml``).
Loading from ``stdin`` is useful with standard input and output redirections.
For example::
django-admin dumpdata --format=json --database=test app_label.ModelName | django-admin loaddata --format=json --database=prod -
``makemessages``
