Django: how to use the checkbox in the admin - django

Question

I try to display the values of checkbox in my view but It's not working..
forms.py
class JoursForm(forms.ModelForm):
class Meta:
model = Event
JOURS = (
(1, 'L'),
(2, 'M'),
(3, 'M'),
(4, 'J'),
(5, 'V'),
)
jours = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple,
choices=JOURS, label= u"répéter les :")
def clean_my_field(self):
return self.cleaned_data['jours']
admin.py
class EventAdmin(admin.ModelAdmin):
form = JoursForm
save_on_top = True
save_as = True
list_per_page = 25
list_display = ('title', 'start', 'end', 'user', 'fin', 'frequency')
fieldsets = (
(None, {
'fields': ('title','start', 'end', 'is_cancelled', 'calendar', 'user', 'description', ('frequency', 'fin' ), 'activated', 'jours',)
}),
)
views.py
if request.method == 'POST':
form = JoursForm(request.POST)
if form.is_valid():
jours = form.cleaned_data.get('jours')
print 'jours', jours
else:
form = JoursForm
I would like to use the values of checkbox but when I save in admin after having tick the boxes, they remain unchecked.
What to do?

Answer 1

Your jours selection is not saved anywhere - there is no modelfield to save it.
To make this work you can create a model for your jours
class Jour(models.Model):
abbrev = models.CharField(length="1")
and add your weekdays in there.
Then you add a field to your Event model:
jours=models.ManyToManyField(Jour)
Then you can just change your form to:
class JoursForm(forms.ModelForm):
class Meta:
model = Event
jours = forms.ModelMultipleChoiceField(widget=forms.CheckboxSelectMultiple,
queryset=Jour.objects.all(), label= u"répéter les :")
However, I am not sure if that is what you want to achieve.
