Django - Cannot update the form

Question

my template has three columns in one form where they work separately. If I give input for contact column and male column it will save in my database. So basically I want to update the male only as contacts,male and female inputs are present in same html form. I can update the contact but male or female inputs. They all are in same page.I want to make them working separately so I can update them.

The problem is that when I give inputs for the it gets posted but not for male and female inputs. Even when I include the contact1 of male class in forms.py,the form does not get submitted.


from django.urls import path , include
from  . import views



urlpatterns = [
    path('', views.index, name='index'),
    path('info/', views.info, name='info'),
    path('features/', views.features, name='features'),
    path('add/', views.add, name='add'),
    path('add/' ,views.success, name='success'),
    path('update/<str:pk_test>/' ,views.update, name='update')
   

]

views.py

def update(request,pk_test):
    template_name = 'update.html' 
  
 
    # if request.method =='POST':
    #     c_form = commentForm(request.POST,instance=contacts)
    #     if c_form.is_valid() :
             
    #         contact = c_form.save()     
    #         messages.success(request, "Contact Updated")
    #         return redirect("success")     
    #     else:     
    #         c_form = commentForm()            
    # context = {
      
    #     'c_form' : c_form,
       

    # }

    contact = Contact.objects.get(id=pk_test)

Hay there k, 
Since You are working with Django , there is a built in Function called (UpdateView),

Before Please check this Project that i did a while ago , it can help you a lot : The Project -- Go to Posts , inside the project tree

Here i will drop a quick example on how that works :

class Update_Posts(UpdateView):
    form_class = Form_Change
    model = MyPosts
    template_name = 'form_page.html'

    # Define a post method
    def post(self, request, pk):
        if self.request.user.admin_user or self.request.user.staff_user or self.request.user.active_user:
            instance = get_object_or_404(MyPosts, pk=pk)
            form = self.form_class(
                self.request.POST, self.request.FILES or None, instance=instance)
            if form.is_valid():
                return self.form_valid(form)
            else:
                print('this data isn\'t Valid')
