python - FormSet saves the data of only one form -

when submitted forms (but on page filled id more 1 form) - formset saves data of 1 form, rest of data disappear...

my template:

 <div id="data">     <form method="post" action="/lookup/" id="test_data">{% csrf_token %}     {{ formset.management_form }}         {% form in formset %}             <section id="test_data_row">             {{ form }}             </section>         {% endfor %}     </form> </div> <div class="bt">     <button type="submit" class="btn btn-default" id="submit_form" form="test_data">submit</button>     <button type="button" class="btn btn-default" id="add" value="add row"/>add row</button> </div> 

my forms.py:

class lookupform(forms.modelform):    class meta:       model =       exclude = () lookupformset = formset_factory(lookupform, can_delete=true) 

my model

class look(models.model):     class meta():         db_table = 'lookup'     id_device = models.charfield(max_length=75)     phone_number = models.charfield(max_length=100)     phone_number_country = models.charfield(max_length=1000)     text = models.charfield(max_length=1000, default=none) 

my views.py:

def manage_articles(request):    lookupformset = modelformset_factory(model=look, exclude=())    if request.method == "post":       formset = lookupformset(          request.post, request.files,          queryset=look.objects.none(),       )       if formset.is_valid():          form in formset:              form.save()       return httpresponseredirect('/')    else:       formset = lookupformset(queryset=look.objects.none())    return render(request, 'req/lookup.html', {'formset': formset}) 

my js (js add new form):

document.getelementbyid('add').onclick = duplicate; var = 0; var original = document.getelementbyid('test_data'); function duplicate() {    var clone = original.clonenode(true); // "deep" clone    clone.id = "test_data" + ++i; // there can 1 element id    original.parentnode.appendchild(clone); } 

you cannot save formset contains multiple forms. suggest change code to:

   if formset.is_valid():        form in formset:             form.save()        return httpresponseredirect('/')
