     1919.. warning:: 
     1920    The field that is passed into the ``formfield_callback`` function in 
     1921    ``form_for_model()`` and ``form_for_instance`` is the field instance from 
     1922    your model's class. You **must not** alter that object at all; treat it 
     1923    as read-only! 
     1924 
     1925    If you make any alterations to that object, it will affect any future 
     1926    users of the model class, because you will have changed the field object 
     1927    used to construct the class. This is almost certainly what you don't want 
     1928    to have happen.
