Rails - Apr 2006 - Re: Rails Digest, Vol 19, Issue 102

Thank you Alain, I am not at all opposed to hiding one link and displaying the
other ( I assume you mean having a div container for each and setting the
appropriate style )

Unfortunately, the problem remains for me that I still do not know how to modify
those style attributes from the action that gets called via the first link, I
still have not had any success doing a page.replace_html, or know if that is
even the right approach.

I would rather
   1/ place the 2 links in the original html,
   2/ hide the 2nd link (clear_the_table) with
               style="display:none"
and then
   3/ hide the first link, and show the 2nd - clear_the_table - link.

When applicable, I find this way simpler to code, understand and debug.

RJS is your friend :

   def  add_stuff
       initial_stuff = ..
       render :update do |page|
           page.replace_html ''stuff_container'', :partial =>
''stuff'' ,
:locals => {:stuff => initial_stuff}
           page.show ''btn_clear_stuff''
       end
       ...
    end
