Re: Adding values to formdata of ModelForm before saving

Super is one of python's greatest mistakes. http://docs.python.org/library/functions.html#super The form is

class class_name(parent_class):

    def method(self, *args, **kwargs):

        super(class_name, self).method(*args, **kwargs)

It's better in Python 3, but Django hasn't been ported over yet.

Thank you for your effort, as far as I can see you understood my problem right and your solution could work... if there wouldn't be that error:

TypeError at /kalender/1/new_termin/

super(type, obj): obj must be an instance or subtype of type

Termin is a model class, NewTerminForm is a modelformclass (Termin is german for appointment). This is the first time I use super() so I don't know how to solve this problem

One minor edit to that:
form.save(request) -> form.save(request, kalender)

Hey,

I tried re-writing your view and form for you -- but I ran into a snag. I don't read German so other than code-wise (and a couple of obvious words, like kalender and participants) I'm not really sure what you're trying to accomplish.

I do see one obvious issue, though. Participants is a many-to-many field in your Model and you're also using the same attribute in your form. Here's something you could try in your form and view:

View:
--------
if request.method == 'POST':
    form = MyForm(request.POST)
    if form.is_valid():
        form.save(request)

Form:
---------
def save(self, request, kalender, commit=True):

    # Get an Instance of the Termin object.
    obj = super(Termin, self).save(commit=True)
  
    # Add the user as a participant if 'add_me' = True
    if self.cleaned_data['add_me']:
        obj.participants.add(request.user)

    # Set the Calendar, Save, and return
    obj.in_calendar = kalender
    obj.save()
    return obj

Hopefully I didn't just confuse you more :) Good luck!
