How do I go about removing something on an update, for example:
I create a new "user" and set first name and last name.
Later I change my mind and want to remove the last name, I only want the first name available in the database.
So I display the current first name and last name on a form in a view, and clear the text field "last name" and hit the submit button.
As DMZ will not validate empty fields on updates, but instead treating it as keep the value currently in the database/object, how do I in above example CLEAR the last name in the database?
