auto_complete never completes, does nothing.

My setup = Rails 2.0, Prototype ''.

I have a simple implementation of auto_complete that for whatever reason
never fires off an ajax request. I found this in the 'controls.js':


I commented this out, still nothing.

Here's my code:

<%= text_field_with_auto_complete :player, :name_last, { :min_chars => 1
} %>

auto_complete_for :player, :name_last

Is there something I'm missing here? I had a colleague look into this
(veteran rails developer) and he was bewildered.

I've also tried using different objects and fields with the same result.

Do you load the JavaScript libraries?

Everything looks fine.

The HTML autocomplete attribute is turned off to avoid triggering browser builtin autocompletion. Leave that off.

The option :min_chars goes in the wrong hash:

      tag_options = {},
      completion_options = {}

but that should fire the call anyway. You end up with and HTML min_chars attribute, but that does not prevent the Ajax request from being issued.

How did you check no Ajax request is sent?

Have you moved forward?

check out your application.rb file and if there is
protect_from_forgery then just comment it.

In that case the request would fail, but it would be a request in firebug.

Download the latest from scriptaculous and unizip it and put it in
your public/javascript folder and overwrite the file that exist there
already. And in your view file make sure to include
<%=javascript_include_tag 'default' %>
<%=javascript_include_tag 'prototype' %>

It works for me. Hopefully, it works for you as well.

I have the same problem as Matt, am running Rails2 via Aptana
RadRails, and have tried the various suggestions to no avail. Has
anyone successfully set this up on Rails 2?


Success! I had ignored this suggestion from Mr. Bless because I had
just installed it on the console via "script/plugin install
auto_complete". What I failed to realize is that for whatever reason,
this does not install the latest version. When I downloaded the
archive from scriptalicious, everything worked as expected!

Thanks Mr. Bless.

Great, I just now found time to revisit this thread i started. I
temporarily abandoned the app I was developing on when I had this
problem but will check it out asap. Thanks guys.

pages weren't loading or erroring.. thanks in advance.
