link_to, image_submit_tag, "changes only with POST" and "usability without Javascript" question

Hello,

I want to have the following features in my rails application: 1. the program should have AJAX if Javascript available 2. I want to protect my application described in URIs, Addressability, and the use of HTTP GET and POST - means GET should be safe 3. if Javascript is disabled the application should work too (without AJAX)

If I use "GET should be safe" option (verify) and link_to with :method => 'post' option these links do not work anymore with Javascript disabled. My idea was now to use image_submit_tag to do e.g. a 'delete' action on list page. For this option I have to encode the action (delete) and the id of the entity within the value option of the generated HTML "input" tag. Is there a plugin for this avalailable? The downside of this is that I have one form action which has to decode the "value" content and delegate to the right action. Did I miss something?

Ok. I solved it. I make a form_tag with a image_submit_tag for each action which modifies something (POST). all others can use link_to (GET).
