Here's an example of how you can use the UpdateView CBV to modify a model instance in Django:

 In Django, you can use the UpdateView class-based view (CBV) to handle update requests for a model instance. The UpdateView CBV will automatically check if the request.user is authenticated and if they are the owner of the object being modified.

Here's an example of how you can use the UpdateView CBV to modify a model instance in Django:

Copy code

from django.views.generic import UpdateView from .models import MyModel from .forms import MyModelForm class MyModelUpdateView(UpdateView): model = MyModel form_class = MyModelForm template_name = 'my_model_update.html' success_url = '/my-models/' def form_valid(self, form): form.instance.user = self.request.user return super().form_valid(form)

In this example, the MyModelUpdateView class is a subclass of UpdateView that handles update requests for instances of the MyModel model. The form_valid method is overridden to set the user field of the form instance to the request.user before saving the form.

To use this view, you would need to define a template called 'my_model_update.html' and map it to a URL pattern in your Django project's URLconf.

I hope this helps! Let me know if you have any questions.
