.. note::
In the usual initialization process, the ``ready`` method is only called
once by Django. But in some corner cases, particularly in tests which
are fiddling with installed applications, ``ready`` might be called more
than once. In that case, either write idempotents methods, or put a flag
on your ``AppConfig`` classes to prevent re-running code which should
be executed exactly one time.
