How do I use an UpdateView to update a Django Model?

Question

I\'m trying to update a model in Django using the class-based generic view UpdateView.

I read the page Updating User model in Django with class based UpdateView to t

Answer 1

views.py

class MyUpdateView(UpdateView):
    model = ModelName  # required
    template_name = 'x/h1.html'
    form_class = ModelNameForm
    success_url = reverse_lazy('app:page1')

    def get_queryset(self):
        """
        Optional condition to restrict what users can see
        """
        queryset = super().get_queryset()
        return queryset.filter(id__lt=20)

    def get_success_url(self):
        return reverse_lazy(
            'app1:abc',
            kwargs={'pk': self.object.id}
        )

urls.py

In urlpatterns=[]

path('xyz//', MyUpdateView.as_view(),name='xyz')

my_model_view.html

{{form}}

You will be able to edit ModelName at url /xyz// where can be anything from 1 to 20 based on our condition in get_queryset(). Take that condition out to allow users to edit any object.

self.object is only available after post request to the UpdateView.
