Django + ManyToMany field + Parsing JSON from fullcalendar (saves empty)

Question

I've a problem. My form saves in views, but then in database it is all empty.

In views, I'm getting parsing JSON, and storing it in eventsParsed model, so then I can update actual from.

I know my code is a bit messy. Can you please advice me how to properly clean it too?

views.py

    args['form'] = TourCreationForm()
if request.method == 'POST':
    form = TourCreationForm(request.POST, request.FILES)
    if 'dates' in request.POST:
        eventsParsed = EventsModel()
        eventsParsed.save()
        jsonDates = request.POST['dates']
        dates = json.loads(jsonDates)
        for date in dates:
            event = CalendarEvent(title=date['title'], start=date['start'], end=date['end'], all_day=date['allDay'])
            event.save()
            eventsParsed.datesForPost.add(event)
        updated_data = request.POST.copy()
        updated_data.__setitem__('dates', eventsParsed.datesForPost)
        form = TourCreationForm(data=updated_data )
    if form.is_valid():
        form.save()

You seem to be skipping the case where form.is_valid() returns false--are you sure the form you're posting is valid? Perhaps add an else and check for errors or re-display the form template (which automatically shows errors). The typical format to follow is here: https://docs.djangoproject.com/en/1.8/topics/forms/#the-view

Also, I'm not sure you want to use tour = models.Manager(). Perhaps a ForeignKey would be more appropriate. Not sure if this is the problem with the form, since you seem to have cropped some of the view code.
