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