[Ncr-Python.in] Generate Dynamic lists

[Asif Jamadar]

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 criteria_list = ['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):



    evaluation_formset = formset_factory(EvaluationForm, formset=BaseEvaluationFormset, extra=6)



    if request.POST:



        formset = evaluation_formset(request.POST)



        ##validation and save



    else:



        formset = evaluation_formset()



    render_to_response(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 form_index, form in enumerate(self.forms):



            form.fields["value"].choices = self.choice_method(form_index)

    def choice_method(self, form_index):

        list = []

        item_list = []

        criteria_list = []

        criteria_length = len(sub_criterias)-1

        for criteria_index in range(criteria_length):

            counter = 1

            if criteria_index == form_index:

                for j in range(criteria_length-counter):
                    x = 1
                    for i in range(6):
                 criteria_list.append((sub_criterias[criteria_index], sub_criterias[criteria_index]))

                        item_list.append((sub_criterias[criteria_index+ 1], sub_criterias[criteria_index+1]))

                        list =  criteria_list +item_list

                        counter = counter + 1
                        if x != criteria_length:

                            x = x + 1



            return list
