   2 21. Specifying 'choices' for a field
   3
   4 Most fields take a ``choices`` parameter, which should be a tuple of tuples
   5 specifying which are the valid values for that field.
   6
   7 For each field that has ``choices``, a model instance gets a
   8 ``get_fieldname_display()`` method, where ``fieldname`` is the name of the
   9 field. This method returns the "human-readable" value of the field.
