Rails - Jan 2006 - first ajax demo in Rails book - does it work for anyone?

Just tried the first AJAX example in the rails book (p.391-392, the
''word guessing'' thing), and the AJAX partial used seems to
render as a
full page.

I''m not sure whether it''s

a) a partial bug
b) some interaction between ajax and partials
c) a change since the book came out
or
d) pilot error

I''ve checked the errata pages and it''s flagged up as b0rked
there too
(on windows; I''m on ubuntu breezy with rails v1.0).

gmane drew a blank on the list archives, can anyone confirm/deny whether this
worked for them?

Could you post the code you''re using?

render :partial => ''yourpartial''

shouldn''t include a layout...

Thanks Jules, but it''s really just the code from the book
(unless I fat-fingered something). It does''nt use a layout,
just a partial.

Essentially the URL updates to point to the action that
form_remote_tag is calling via AJAX, which I don''t think it
should.

I can post code if this is ringing no bells at all...

Please post your code if this:

render :partial => ''form'', :layout => false

doesn''t help.

I''ll be looking at these incompatibilities over the coming months:  
I''m guessing that adding :layout => false will fix it.


Dave

that code (p. 392 in the printed version if I''m following you) is  
noted as erroneous at the book''s Web site:

http://books.pragprog.com/titles/rails/errata

Not sure if the comment following that one will help you because I  
didn''t see your original post on this thread.

On my .pdf version of the book, your book has:

render(:layout => false)

Nope, still b0rked - here''s all the source

Thanks for everyone''s suggestions so far, and apologies in advance

To clarify, I''m talking  about the deadtree version, and adding
the :layout => false key to the options hash does''nt appear
to make any difference.
