Ahh I see. I use one of two ways to do that
1. make extra forms for the little onchange etc requests I want to do. Eg a form with just an email field in it. Or a form with just the two passwords in it.
Or 2. If I’m updating a model object, I like to use hx-patch, and in the view I test if it’s a patch request, and if it is, I get the model object’s data as a dict and merge that with the data in the hx-patch request, create a model form instance using that, validate etc, and then respond with what makes sense. I can paste some code when I’m back at my pc if that helps
