Re: formset has_changed always return true.
Hi!
Have you instanced first de form?
Maybe this code from djano help you
from django.http import HttpResponseRedirectfrom django.shortcuts import render
from .forms import NameForm
def get_name(request):
# if this is a POST request we need to process the form data
if request.method == 'POST':
# create a form instance and populate it with data from the request:
form = NameForm(request.POST)
# check whether it's valid:
if form.is_valid():
# process the data in form.cleaned_data as required
# ...
# redirect to a new URL:
return HttpResponseRedirect('/thanks/')
# if a GET (or any other method) we'll create a blank form
else:
form = NameForm()
return render(request, 'name.html', {'form': form})
Maybe you can check has_changed() after form=
Nameofyourforminformspy(request.POST) ?
good luck
