28033	Allow passing choices as a callable in a model field	Ian Foote	Rémy Hubscher	Currently [https://docs.djangoproject.com/en/1.11/ref/models/fields/#choices Field.choices] requires a fixed iterable, but this is not flexible for choices that depend on information like the current date/time (eg I want the next five years) or a value from {{{settings.py}}} which might change between projects. Allowing a callable to be passed would allow the current choices to be generated on demand and would avoid causing spurious migrations when a setting is changed.
