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:  
 ![Notes](https://test.ruby-forum.com/images/notes3.png)

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:

\*should show up here\*

That part is visible, but the text never gets replaced. I’ve tried with  
Camino and Safari so far.

Thanks in advance,

Micah

Try to include the following

\<%= javascript\_include\_tag :defaults %\>

in your .rhtml file

Feng, thanks! That just works.

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.

This was very strange. I still don’t know what’s going on. 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.

1. 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.

**render :layout =\> false** works at home =(  
show\_note.rhtml is used and not the main layout…
