Hello there
I've got an event model, which has an association with multiple
workshops
models.py
class Event(models.Model):
workshops = models.ManyToManyField(Workshop,
related_name='evt_workshop', limit_choices_to = {'lang_code__in':
('B', 'E')}, blank=True, null=True)
I've got a form that I then use to create the email, with the view
forms.py
class EventBookForm(ModelForm):
workshops = MultipleChoiceField()
views.py
def event_book(request,edate, slug):
I run through some logic here based on request type, and put together
the email that sends off the selected items
I also throw data back to the form, like this
eventdetail = Event.objects.filter(slug=ventslug,start_date=ventdate)
for d in eventdetail:
workshopid = d.id
workshop = Workshop.objects.filter(evt_workshop=workshopid)
cats = formextra.objects.all()
context = Context({'form': form, 'cats': cats, 'eventdetail':
eventdetail, 'workshop': workshop })
return render_to_response('forms/eventbookform.html', context,
context_instance=RequestContext(request))
My problem is this
I can't find a way to list the workshops that are associated with the
event AND send which ones are selected in the tick boxes in the email.
I can list the workshops that are associated with the event in the
view
workshops = Workshop.objects.filter(evt_workshop=d.id)
workshoptitlearray = ''
for w in workshops:
workshoptitle = w.title
workshoptitlearray = workshoptitlearray + ', '
+ w.title
I think I need to do something like this in the form though, in order
to send the items that have been selected
class EventBookForm(ModelForm):
workshops = MultipleChoiceField()
requirements = CharField(widget=Textarea(attrs={'rows': 5, 'cols':
80}))
class Meta:
model = Event
def __init__(self, *args, **kwargs):
self.request = kwargs.pop('request', None)
super(EventBookForm, self).__init__(*args, **kwargs)
workshop_choices = []
data = Workshop.objects.all()
print data
for d in data:
workshop_choices.append((d.title,d.title))
self.fields['workshops']=MultipleChoiceField(widget=CheckboxSelectMultiple,
choices=workshop_choices, required=False)
As you can see, I'm getting myself into a bit of a mess here, if
anyone can shed any light on how I access the information passed from
the view
context = Context({'form': form, 'cats': cats, 'eventdetail':
eventdetail, 'workshop': workshop })
return render_to_response('forms/eventbookform.html', context,
context_instance=RequestContext(request))
Any help, greatly appreciated, as always
