Re: Passing parameters to form class

Yes, you will want to do this within the __init__ method.

Run the super class's init method first so that everything's
initialized as normal.

Then you will have to grab the field for that instance within the
__init__ method (self.fields['vaihtoehdot']) and set the choices
property for it.
