I would use a related model and a many-to-many link. Something like the
following:
class DaysOfWeek(models.Model):
day = models.CharField(maxlength = 3, choices = WEEKDAYS)
class OtherModel(models.Model):
days = models.ManyToManyField(DaysOfWeek)
...
and create a WEEKDAYS list like (('Mon', 'Monday'), ('Tue',
'Tuesday'), ...). You could even use (('Monday', 'Monday'), ...) if you
wanted. I just use the 'choices' attribute to restrict the possibilities
a little there. It's optional.
The advantage of this method is that now all days are the same and you
can get the list of days that are selected using other_model.days.all(),
etc, so access becomes less fiddly in many situations.
By the way, if you are rolling your own form and custom manipulator, the
CheckboxSelectMultipleField form class can be useful here, too.
