Yet another class to simplify field choices creation. Keeps order, allows i18n.
Before:
ONLINE = 0
OFFLINE = 1
STATES = (
(ONLINE, _('online')),
(OFFLINE, _('offline'))
)
state = models.IntegerField(choices=STATES, default=OFFLINE)
After:
STATES = Choices(
('ONLINE', _('online')),
('OFFLINE', _('offline'))
)
state = models.IntegerField(choices=STATES, default=STATES.OFFLINE)
1 2 3 4 5 6 7 8 9 | class Choices(object):
def __init__(self, *args):
self._choices = []
for i, arg in enumerate(args):
setattr(self, arg[0], i)
self._choices.append((i, arg[1]))
def __iter__(self):
return iter(self._choices)
