Model Choices Helper
This is my attempt at a convenience class for Django model choices which will use a [Small]IntegerField for storage. It's very similar to [jacobian's version](http://www.djangosnippets.org/snippets/1664/), but I wanted to be able to use simple attributes for access to the integer values. It's not technically dependent on Django, but it's probably not a datatype that would be useful for much else. Feel free to do so however if you have a use-case. >>> statuses = Choices( ... ('live', 'Live'), ... ('draft', 'Draft'), ... ('hidden', 'Not Live'), ... ) >>> statuses.live 0 >>> statuses.hidden 2 >>> statuses.get_choices() ((0, 'Live'), (1, 'Draft'), (2, 'Not Live')) This is then useful for use in a model field with the choices attribute. >>> from django.db import models >>> class Entry(models.Model): ... STATUSES = Choices( ... ('live', 'Live'), ... ('draft', 'Draft'), ... ('hidden', 'Not Live'), ... ) ... status = models.SmallIntegerField(choices=STATUSES.get_choices(), ... default=STATUSES.live) It's also useful later when you need to filter by your choices. >>> live_entries = Entry.objects.filter(status=Entries.STATUSES.live)
