Hello.

We are sorry but we cannot help you. This mailing list is to work on developing Python (adding new features to Python itself and fixing bugs); if you're having problems learning, understanding or using Python, please find another forum. Probably python-list/comp.lang.python mailing list/news group is the best place; there are Python developers who participate in it; you may get a faster, and probably more complete, answer there. See http://www.python.org/community/ for other lists/news groups/fora. Thank you for understanding.

So I'm trying to generate dynamic choices for django form. Here i'm usig formset concept (CODE is mentioned below)

Suppose i have list called criterialist = ['education', 'know how', 'managerial', 'interpersonal', ] now i need to generate choices as follows list1 = [('education', 1), ('education', 2), ('education', 3), (''education' , 4) , ('know how', 1) ('know ho', 2), ('know ho', 3), ('know ho', 4)] list2 = [('education', 1), ('education', 2), ('education', 3), (''education' , 4) , ('managerial', 1) ('managerial', 2), ('managerial', 3), ('managerial', 4)] list3 = [('education', 1), ('education', 2), ('education', 3), (''education' , 4) , ('interpersonal', 1) ('interpersonal', 2), ('interpersonal', 3), ('interpersonal', 4)] list4 = [('know how', 1), ('know how', 2), ('know how ', 3), ('know how' , 4) , ('managerial', 1) ('managerial', 2), ('managerial', 3), ('managerial', 4)] list5 = [('know how', 1), ('know how', 2), ('know how ', 3), ('know how' , 4) , ('interpersonal', 1) ('interpersonal', 2), ('interpersonal', 3), ('interpersonal', 4)] list6= [('managerial', 1), ('managerial', 2), ('managerial ', 3), ('managerial' , 4) , ('interpersonal', 1) ('interpersonal', 2), ('interpersonal', 3), ('interpersonal', 4)]

How can i achive this in python? The above all eachh list become the choices for each form. Suppose i have formset of 6 forms. Then how can i assign above dynamic generates list to the choice field of each form. I tried by using this following code but no luck view.py def evaluation(request): evaluationformset = formsetfactory(EvaluationForm, formset=BaseEvaluationFormset, extra=6) if request.POST: formset = evaluationformset(request.POST) ##validation and save else: formset = evaluationformset() rendertoresponse(formset) forms.py class EvaluationForm(forms.Form): value = forms.ChoiceField(widget=forms.RadioSelect(renderer=HorizontalRadioRenderer)) class BaseEvaluationFormSet(BaseFormSet): def init(self, *args, **kwargs): super(BaseEvaluationFormSet, self).init(*args, **kwargs) for formindex, form in enumerate(self.forms): form.fields["value"].choices = self.choicemethod(formindex) def choicemethod(self, formindex): list = [] itemlist = [] criterialist = [] criterialength = len(subcriterias)-1 for criteriaindex in range(criterialength): counter = 1 if criteriaindex == formindex: for j in range(criterialength-counter): x = 1 for i in range(6): criterialist.append((subcriterias[criteriaindex], subcriterias[criteriaindex])) itemlist.append((subcriterias[criteriaindex+ 1], subcriterias[criteriaindex+1])) list = criterialist +itemlist counter = counter + 1 if x != criterialength: x = x + 1 return list
