Re: Adding values to formdata of ModelForm before saving

Thank you for your quick answer, but it doesn't really work. It raises the exception "can't assign to operator"
My view now looks like this:

@login_required
def create_termin(request, calid, year=None, month=None, day=None):
    kalender = get_object_or_404(Kalender,pk=int(calid))
    if request.method == "POST":
        print(request.POST)
        form = NewTerminForm(request.POST)

        if form.is_valid():
            formdata = form.cleaned_data
            if formdata['participants']:
                form.participants = request.user.id
            form.save(commit=False)
            form.in_calendar-id = kalender
            form.save()
            return HttpResponse(pprint.pformat(formdata) + pprint.pformat(inspect.getmembers(form['participants'])) + "\n\n" + pprint.pformat(inspect.getmembers(request.user)),mimetype="text/plain")

    else:
        date = datetime.date(month=int(month), day=int(day), year=int(year)) if day else None
        print("viewdate",date)
        form = NewTerminForm(initial={'date':date,})
    return render_to_response("kalender/new_termin.html", dict(debug=1, calid=calid,form=form, ),context_instance=RequestContext(request))

Yes, it is possible:

obj = form.save(commit=False)

obj.in_calender-id = kalender

obj.save()

Is it possible to put missing data into the data of a form before calling form.save() ?
I want to add the calendar-id (calid/in_calendar) before saving to the model.

 http://susepaste.org/23451355

I tried adding it after instantiating the form with form.in_calendar_id = kalender but it didn't work
I don't want to use hidden fields because manipulating them is easy

Maybe https://groups.google.com/forum/?fromgroups#!topic/django-users/F5yHH-G5QLM describes how to solve it but I didn't understand it.

PS: If you find very ugly code please correct me -- I'm a beginner
