This is not true. `params` is available in the view. It's not always a good
idea to *use* it there, but it's available.
Relating to the original question, the difficulty appears to be that the
link isn't going to pick up the client-side checkboxes. This code:
:employee.id => params[:retrieve_case[]]}, { :class => 'submit_button' },
:method => 'post'
doesn't make any sense.
I'd recommend getting this form to work with a real submit button and
without AJAX *before* complicating it.
Also: 2.3.5 is deeply, wildly out-of-date. At a minimum, you should upgrade
to the last security release of 2.3.x as there are SEVERE issues in older
versions.
