Django Formset hat nur ein Formular mit Daten, verbleibende haben leere Daten

Question

Ich verwende Django Formsets, um mehrere Formulare zu haben. Zunächst habe ich nur ein Formular, und ich füge mehr Formen mit JavaScript dynamisch hinzu. Wenn ich dieses Formular absende, hat request.POST Objekt nur die Daten für das erste Formular. Wenn ich Formset gesetzt habe, um zwei Formulare zu zeigen und zu senden, hat es beides. Das Problem tritt auf, wenn ich neue anhängen mit javaScript

//forms.py 
from django import forms 

class AddUserForm(forms.Form): 
first_name = forms.CharField(max_length=50) 
last_name = forms.CharField(max_length=50) 
email = forms.EmailField() 
password1 = forms.CharField(widget=forms.PasswordInput) 
password2 = forms.CharField(widget=forms.PasswordInput) 


//views.py (this one to handle the get) 
if request.method == 'GET': 
    add_user_formset = formset_factory(AddUserForm, extra=1, max_num=6) 
    context['add_user_formset'] = add_user_formset 

//view.py (this one to handle the post of the form) 
@login_required(login_url = reverse_lazy('login')) 
def add_users(request, ir_id): 
    if request.method == 'POST': 
     my_form = formset_factory(AddUserForm) 
     my_formset = my_form(request.POST) 

     if my_formset.is_valid(): 
      for form in my_formset: 
       if form.is_valid(): 
        email = form.cleaned_data['email'] 
        username = form.cleaned_data['email'] 
        first_name = form.cleaned_data['first_name'] 
        last_name = form.cleaned_data['last_name'] 
        password = form.cleaned_data['password1'] 
        user = User(email=email,first_name=first_name,last_name=last_name,username=username) 
        user.set_password(password) 
        user.save() 
        new_user_profile = UserProfile.objects.get(id=user.id) 
        new_user_profile.user_role = users_role[0][0] 
        new_user_profile.save() 
        ir_obj = IR.objects.get(ir_id=int(ir_id)) 
        ir_obj.users.add(new_user_profile) 
    return HttpResponseRedirect(request.META.get('HTTP_REFERER')) 



//template 
<form action="{% url 'add_users' ir_id %}" method="post" >{% csrf_token %} 
        {{add_user_formset.management_form}} 
        {% for item in add_user_formset%} 
         <tr> 
          <td><div>{{item.first_name}}</div></td> 
          <td><div>{{item.last_name}}</div></td> 
          <td><div>{{item.email}}</div></td> 
          <td><div>{{item.password1}}</div></td> 
          <td><div>{{item.password2}}</div></td> 
         </tr> 
        {% endfor %} 
        <input type="submit" name="submit" class="btn btn-primary" value="Create account"> 
        </form> 





//JavaScript 

    $(document).on("click", ".irStatus-add-another-user", function() { 
    var count = parseInt($('#id_form-TOTAL_FORMS').val()) 
    var newRow = $('.add-users-table tbody tr:last').clone(true) 

    newRow.find(':input').each(function(){ 
     var name = $(this).attr('name').replace('-' + (count-1) + '-','-' + (count) + '-'); 
     var id = 'id_' + name; 
     $(this).attr('id', id); 
     $(this).attr('name', name); 
     $(this).val(''); 
    }) 
    newRow.appendTo('.add-users-table tbody') 
    $('#id_form-TOTAL_FORMS').val(''+(count+1)) 
});

Sie benötigen <form>-TOTAL_FORMS Feld von Ihrem Management Form von Java-Skript zu erhöhen, als auch, wenn Sie ein neues Formular hinzufügen, da das formset dieses Feld verwendet das, um zu bestimmen Anzahl der bereitgestellten Formulare. Formset Management Form docs
