AJAX & Ruby & Rails newbie here.
I''ve got a link to remote that I believe should be working, but
doesn''t
seem in fact to do *anything*. I''m looking at the webrick log, since
the Book says I should be seeing some hot POST action in there, but
there''s literally no change when I click on the JS link. From looking
at
the source that''s generate, it seems like it should work. If I take the
link it generates there out and put it in the address bar, it works
fine.
Here''s the code:
link_to_remote(image_tag("/images/notes3.png", :size =>
"28x30", :alt =>
"Notes", :border => "0"), :update =>
"note#{project.id}", :url => {
:action => :show_note, :id => project.id })
Here''s the resulting JS:
<a href="#" onclick="new
Ajax.Updater(''note1'',
''/project/show_note/1'',
{asynchronous:true, evalScripts:true}); return false;"><img
alt="Notes"
border="0" height="30" src="/images/notes3.png"
width="28" /></a>
I don''t think that :show_note is even being hit (but I''m not
sure how to
check that).
The HTML where this should go to is:
<div id="note<%= project.id -%>">*should show up
here*</div>
That part is visible, but the text never gets replaced. I''ve tried with
Camino and Safari so far.
Thanks in advance,
Micah

Now if I could just figure out why the damn layout keeps re-rendering itself. I have tried about 10 combinations to try and stop it with no luck: def show_note @notes = self.project_notes #render(:layout => false) #render :layout => false #render(:partial => "show_note", :collection => @notes) #render :partial => "/show_note" render :action => "show_note", :layout => false end no errors in any of those, but none of them make any difference at all. -- Posted via http://www.ruby-forum.com/.
**render :layout => false** works at home =( show_note.rhtml is used and not the main layout.. pmt -- Posted via http://www.ruby-forum.com/.

It works now, but I had to change things. 1) it turns out with the link_to_remote code above, the Project.show_note method was never getting called at all. It was going right to the show_note.rhtml file (I assume that''s known, but the impression I got from the book example is that this would be going to a method (hence the render: bit). So I just made show_note.rhmtl into a shell, with this only: <%= render :partial => ''show_note'' %> And took the guts of it and put it into "_show_note.rhtml". This works fine, it doesn''t render the layout again. 2) if I tried to change the link_to_remote so that instead of :show_note, the action was project.show_note, that DID call the project show_note method. Unfortunately, it didn''t seem to pass the ID to it, and also, all the "render" calls I tried came up as unknown methods or something. So I gave up on that for now. I think I want a whole Rails book on just AJAX<>Rails. Micah -- Posted via http://www.ruby-forum.com/.
