Rendering partial from button click, not passing locals ?

I wrote the relevant code in this pastie: http://pastie.org/770642 (it's not too much code -- but it looks a ton better than black on white!)

And here is the bit from my log:

Processing UltrasoundsController#index (for 127.0.0.1 at 2010-01-07 10:32:03) [GET] Rendering template within layouts/application Rendering ultrasounds/index Completed in 172ms (View: 16, DB: 105044) | 200 OK [http://localhost/ultrasounds\]

Do you know why "rows" doesn't get passed, like I would expect it to?

best choice is ajax

don’t you need to specify

%p== #{rows} updated

??

According to the HAML reference: http://haml-lang.com/docs/yardoc/file.HAML_REFERENCE.html#ruby_interpolation_

%p This is #{h quality} cake!

This should work. So I was missing the 'h', which I added: %p #{h rows} updated.

But .. No cigar.

I tried these: %p #{h rows} updated. %p= "There were #{h rows} updated. %p There were #{h rows} updated. %p== There were #{h rows} updated.

I always got a "0" where "rows" was interpolated. So ... Either the variable isn't passed correctly, or it is, and the result is zero.

Well, I tried to run one of the update queries using the run_query method in irb, and got a result of 5... Which surprised me because the result should have been one. So there's probably a few things going on here...

sounds like a good place to start with a test (results.size.should == 1)

good luck - ‘ruby-debug’ is on of my favorite tools for stuff like this.
