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 HttpResponseRedirect  from 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

       if request.method == "POST":

            formset = forms.Formset(data=request.POST, initial=initial)

            if not formset.has_changed(): #has_changed always returns true! 

                msg = "No changes detected."

            if formset.has_changed() and formset.is_valid()

                do stuff...

        else:

            formset = forms.Formset(initial=initial)

            formset_get = formset

What am i doing wrong?
