I've made some attempted to use formwizard but there wasn't much documentation about it so I decided to stay with the basic. I've successfully obtained and display the data from the first form to the second form and added some checkbox next to the data to allow user to choose whether to overwrite or ignore the duplicate data found in the backend process. The problem I have is the second form doesn't know how retrieve the data of the first form after hitting "Confirm" button. The form2.html template invalidated the data completely since it called itself again by the form action after submitting the data. Is there a way to solve this or a better approach to this?
forms.py
last_name = forms.CharField (required = False)overwrite = forms.BooleanField (required = False)
views.py
def form1 (request):
NameFormSet = formset_factory (NameForm, formset = BaseNodeFormSet, extra = 2, max_num = 5)
if request.method == 'POST':
name_formset = NameFormSet (request.POST, prefix = 'nameform')
if name_formset.is_valid ():
data = name_formset.cleaned_data
context = {'data': data}
return render (request, 'nameform/form2.html', context)
else:
name_formset = NameFormSet (prefix = 'nameform')
context = {......}
return render (request, 'nameform/form1.html', context)
def form2 (request):
CheckBoxFormSet = formset_factory (CheckBox, extra = 2, max_num = 5)
if request.method == 'POST':
checkbox_formset = CheckBoxFormSet (request.POST, prefix = 'checkbox')
if checkbox_formset.is_valid ():
data = checkbox_formset.cleaned_data
context = {'data': data}
return render (request, 'nameform/success.html', context)
else:
checkbox_formset = CheckBoxFormSet (prefix = 'checkbox')
return HttpResponse ('No overwrite data.')
