Any keyword arguments passed to ``get_or_create()`` — *except* an optional one
called ``defaults`` — will be used in a :meth:`get()` call. If an object is
found, ``get_or_create()`` returns a tuple of that object and ``False``. If an
object is *not* found, ``get_or_create()`` will instantiate and save a new
object, returning a tuple of the new object and ``True``. The new object will
be created roughly according to this algorithm::
found, ``get_or_create()`` returns a tuple of that object and ``False``. If
multiple objects are found, ``get_or_create`` raises
:exc:`~django.core.exceptions.MultipleObjectsReturned`. If an object is *not*
found, ``get_or_create()`` will instantiate and save a new object, returning a
tuple of the new object and ``True``. The new object will be created roughly
according to this algorithm::
defaults = kwargs.pop('defaults', {})
params = dict([(k, v) for k, v in kwargs.items() if '__' not in k])
