I have a django application and for a particular form,the data comes from different models with one common field(id) across all models.Instead of using multiple forms and same id for all forms,I want to use a single form to take data from multiple models.How can this be done?

- Specify your form as provided in the django docs: https://docs.djangoproject.com/en/1.10/topics/forms/#building-a-form-in-django
- Specify the view e.g.
view.py
def get_name(request):
id = request.kwargs['id'] # Get the id from url or however you want to get the id
item = Item.objects.get(name_id=id)
item2 = Item2.objects.get(name_id=id)
# 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
# ... e.g.
item.name = form.cleaned_data['name']
item2.name = form.cleaned_data['name2']
item.save()
item2.save()
# redirect to a new URL:
return HttpResponseRedirect('/thanks/')
# if a GET (or any other method) we'll create a blank form
else:
# This is for updating the "name" objects
form = NameForm(initial={'name': item.name, 'name2': item2.name})
# for creating: (but I guess you don't need creating)
# form = NameForm()
return render(request, 'name.html', {'form': form})
- Handle the form in the template as you normally would.
