Could somebody explain how to accomplish the following behavior. It feels just out of reach with ad_form.
0) a page called "object-edit"
1) A single block of code that includes
a) sql code or tcl api calls to retrieve a record, update a record, or create a record
b) description of the fields to display and the html elements to use
2) browsing to "object-edit" displays a form to add an object, with a button labelled "Add" (or using the acs-kernel message key for Add).
2a) After clicking "Add", page redirects to "object-edit?id=47" and shows the object in a read-only version of the form
3) browsing to "object-edit?id=47" shows object 47 in read-only mode
4) browsing to "object-edit?id=47&mode=edit" shows object 47 in edit mode
