django days-of-week representation in model

You may want to create DayOfTheWeek field type, which you can improve in various ways.

This code cause to translate automatically into the local language using the multilingual tools.

#myFields.py
from django.utils.translation import ugettext as _

DAY_OF_THE_WEEK = {
    '1' : _(u'Monday'),
    '2' : _(u'Tuesday'),
    '3' : _(u'Wednesday'),
    '4' : _(u'Thursday'),
    '5' : _(u'Friday'),
    '6' : _(u'Saturday'), 
    '7' : _(u'Sunday'),
}

class DayOfTheWeekField(models.CharField):
    def __init__(self, *args, **kwargs):
        kwargs['choices']=tuple(sorted(DAY_OF_THE_WEEK.items()))
        kwargs['max_length']=1 
        super(DayOfTheWeekField,self).__init__(*args, **kwargs)

#models.py
import myFields
(..)
    dayOfTheWeek = myFields.DayOfTheWeekField()
(..)

If you want a checkbox for each one, then the easiest thing to do is to create BooleanFields for each of them. If you want to store it as a more complex value (eg. comma separated list or something), create your own widget and play with javascript, then you could go that route.

Something like this would work.

#models.py
DAYS_OF_WEEK = (
    (0, 'Monday'),
    (1, 'Tuesday'),
    (2, 'Wednesday'),
    (3, 'Thursday'),
    (4, 'Friday'),
    (5, 'Saturday'),
    (6, 'Sunday'),
)

days = models.CharField(max_length=1, choices=DAYS_OF_WEEK

#forms.py
widgets = { 'days': forms.CheckboxSelectMultiple }

Or to save multiple days

#models.py
class Days(models.Model):
    day = models.CharField(max_length=8)

days = models.ManyToManyField(Days)

#forms.py
widgets = { 'days': forms.CheckboxSelectMultiple }
