Rails - Apr 2009 - RJS not rendering correctly when mime-type is 'iphone'

I have an iPhone version of my site, and for some reason none of the
rjs works when viewing the iPhone version. This happens instead:

ActionView::MissingTemplate (Missing template controller_name/
update.erb in view path app/views)

The rjs works fine when viewing the site normally, and it worked when
viewing the iPhone version prior to upgrading Rails to 2.3.2.

Additional info: I have ''Mime::Type.register_alias "text/
html", :iphone'' in mime_types.rb and the respond_to block in the
action is what''d you expect --

respond_to do |format|
   format.js
end

What could be the problem? Thanks.

No one knows why this is happening? I created a new rails app from
scratch, first uncommenting "Mime::Type.register_alias "text/
html", :iphone" in mime_types.rb. Then I put this in my application
controller:

--------
before_filter :adjust_for_iphone

def adjust_for_iphone
   request.format = :iphone if
request.env[''HTTP_USER_AGENT''][/(Mobile
\/.+Safari)/]
end
--------

I created an index controller, with an index and test action
(index.html.erb, index.iphone.erb, test.js.rjs), and put a remote link
in the index action to call test. Without any respond_to block in the
test action, I get this:

--------
ActionView::MissingTemplate (Missing template index/test.erb in view
path app/views)
--------

When this block is added to the test action:

--------
respond_to do |format|
   format.js
   format.iphone { render ''test.js.rjs'' } # also tried without
this
render block
end
--------

There are no errors whatsoever, however the rjs doesn''t get executed
at all, even with Firebug showing the js in the response. Surely
someone can help with this?

The problem would appear to be that you''ve got your iphone mime-type 
defined as text/html.  This means that even though Rails is correctly 
processing the RJS file, it is telling the browser that the file is 
HTML, not JavaScript.  You''ll need a separate type (iphone_js or 
something) defined as text/javascript.

RJS is evil anyway. :)

Thanks for the advice; it worked fine pre-2.3 though. I added
"Mime::Type.register_alias "text/javascript", :iphonejs" to
mime_types.rb and put "format.iphonejs" in the respond_to block, but
now I get a 406 Not Acceptable error. Am I doing it wrong?

I''m not sure why this would ever have worked, but then again MIME type 
mapping is one of my weak spots in Rails.

Did you restart the server?  If I remember correctly, defined MIME types 
are only loaded at server startup.

You must be, since you''re not getting the right result. :D

But I''m not sure where the problem is, if restarting the server
doesn''t
do the trick.

I made a new app and I started from scratch. After following the steps
in my previous posts, I still get 406 errors. This is so strange; it
seems like I''m the only one in the world having this problem with 2.3!
Anything else I can do?

Hmm.  I forgot to ask: what''s the name of the RJS file? I should be 
something.iphonejs.rjs...
