How to delete without javascript

I'm trying to make my application work with DELETE action without javascript.

Evrything work as long as my app/view/layout/application.html.haml file do contain the following :

!!! 5
%html

  %head
    %title My application
    = stylesheet_link_tag    'screen', :media => 'screen, print, projection'
    /[if IE]
      // CSS for IE
    = javascript_include_tag 'application'
    = csrf_meta_tags

  %body
    ...

If I remove the = javascript_include_tag 'application' instruction. I can no more delete any record. Rails is instead performing a SHOW action.

Any idea ?

Ryan Bates made a nice RailsCasts episode on this issue: Destroy without JavaScript.

He simply suggests to add an extra GET member route which will lead to the same controller action when JS is disabled.

The only two supported methods when writing HTML forms are post and get. If you want to use the delete or put method you must use AJAX.

That is the reason why most websites use a plain post request and use a special URL. e.g.

POST /some-object/delete/

or

POST /some-object/?action=delete

Not even the latest HTML5 draft allows any other method than post or get: http://www.w3.org/html/wg/drafts/html/master/forms.html#attr-fs-method

Rails provides a polyfill for performing put and delete requests. I find this troubling especially as the code does something completely different when JavaScript is disabled.
