I have an old Rails application that I''d previously upgraded to Rails
3.1
with a lot of legacy features left on; now I want to switch to using jQuery
instead of Prototype, and switch to using the asset pipeline.
I''m trying to tackle the first of those; no idea if that''s
wise, maybe I
should start with the asset pipeline instead? To switch to jQuery, I added
gem ''jquery-rails''
to my Gemfile and replaced
<%= javascript_include_tag "prototype", "rails" %>
with
<%= javascript_include_tag "
http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js" %>
<%= javascript_include_tag "rails" %>
(I suspect that I''m doing something pretty wrong there, but I
don''t know
what.) And I removed all the prototype-specific JavaScript from my files.
The problem that I''m running into is this: I have a form with the
following
code:
<%= form_tag url_for(:action => :answer, :item => ask), :remote =>
true, :id
=> "show-answer" do %>
<%= submit_tag "Answer" %>
<% end %>
It''s supposed to return the response from answer.js.erb. Unfortunately,
when
I do that, I get the following complaint:
template quiz/answer, application/answer with {:handlers=>[:builder, :erb],
:formats=>[:html], :locale=>[:en, :en]}. Searched in: *
"/home/carlton/memory/app/views"
So it''s looking for HTML instead of JavaScript; and, indeed, the
Accept:
header says:
text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
(I guess that */* at the end is too low priority for it to have an effect.)
I tried explicitly responding only to format.js in my controller action, but
then I got a 406 Not Acceptable response.
Any suggestions as to how I''m wiring this wrong? (I have no idea where
that
Accept: header is coming from, I''m certainly not setting it.) I guess
the
next thing I''ll try is switching over to the asset pipeline;
it''s not clear
to me why that would make a difference, but I don''t really understand
how
the jquery-rails gem takes effect, so it''s entirely possible that
I''m
inadvertently completely bypassing it somehow.
Thanks,
David Carlton
