What is the best practices to track action id in controller for saved form?

Wasnt sure how to word the question, but this is the scenario:

the view is a data entry form eg http://127.0.0.1/User/AddEdit/

so edit the user I have an ID: http://127.0.0.1/User/AddEdit/7838fd9c-425c-4c98-b798-771bba10d9c1

This ID gets the data to populate the form values in a ViewModel, which populates the form

I am using jquery/ajax to save the form, which returns a Json result, indicating ok/error etc

In the View, I get the ID and use this in a hidden field which is set via jquery when the page loads and when the form is saved via ajax.

This 开发者_JAVA技巧seems a bit clunky, how do others do this?

in my opinion best solution is to create a partial view with all the fields and use it on add and edit view which are separate actions in controller. after you create user you can redirect to action edit. if you must / like use ajax you can reload div with form (change from user/add to user/edit/1). i might be wrong but i never see a code or example with one action in controller for add and edit.
