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. On Thu, Oct 20, 2011 at 06:51:05PM +0000, Asif Jamadar wrote:

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

I believe this is not the correct forum for this as it does not concern development of Python language itself - you should post to comp.lang.python. However solutions is relatively simply, try this: list1,list2,list3,list4,list5,list6 = [ list(itertools.product(i,range(0,4))) for i in itertools.combinations(criteria_list,2) ] Best Regards, Jacek Pliszka 2011/10/20 Asif Jamadar :
