Problem with Rails 2.0 auto_complete plugin

I am having same problem.

I just downloaded the plugin for auto_complete but nothing.
I also realized that Scriptaculous.js was not there. 

Is that right that ScriptaculousHelper is not added to 2.0?  What the hack?

Wow, four in one.

auto_complete has been taken out of Rails and put into a plugin. You can all download it via script/plugin install auto_complete, or from here:

http://svn.rubyonrails.org/rails/plugins/auto_complete/

If you are working on a pre existing project, migrated from rails 1.2.# generate a new project and copy over those js files.  For me, if i downloaded prototype from the website i would get client side errors with the js and thus nothing would appear.  What i did to get everything working was this:

In your controller keep the condition:

auto_complete_for :event, :location

<%= text_field_with_auto_complete :event, :location, {}, :skip_style => true %>

div.auto_complete ul {
              border:1px solid #888;
              margin:0;
              padding:0;
              width:100%;
              list-style-type:none;
            }
div.auto_complete ul li {
              margin:0;
              padding:3px;
            }
div.auto_complete ul li.selected {
              background-color: #ffb;
            }
div.auto_complete ul strong.highlight {
              color: #800;               margin:0;
              padding:0;
            }

So continuing on with the investigation of my issue, I tried to use the straight Scriptaculous Ajax.Autocompleter as mentioned here: http://codeintensity.blogspot.com/2008/ … -new.html. And still FireBug shows me a GET request to my auto_complete_for function, then another GET request to my new action. No autocomplete.

Then I tried to swap out Prototype/Scriptaculous completely for jQuery as mentioned here: http://codeintensity.blogspot.com/2008/ … -new.html. The only difference being that with jQuery, it would appear that I'm getting 4 GET requests instead of two. The first once again to my auto_complete_for function, the second to my new action, then repeat.

Has anyone got an AJAX autocomplete working with Rails 2.1.0, in any way at all? If so could anyone post some examples of how they did it?

I would consider giving my first born child in payment for assistance with this problem.

Hi, I'm the author of the codeintensity blog entries you referred to.  I can't vouch for the Prototype based versions in Rails 2.1, but I use the jQuery one, as per my blog entry in Rails 2.1.  A couple things to mention.  First, do you have routes in for the auto complete functions?  I found I had to do that.  I use something like this to handle them all in one route definition:

# Handle all auto_complete routes:
map.auto_complete ':controller/:action', :requirements => { :action => /auto_complete_for_\S+/ },
                                         :conditions => { :method => :get }

Finally, I'm not sure I followed what precise problem you're having at this point.  Are your auto-complete methods being called?  If not, one way that's easier to debug is to not use the plugin's implementation, but just write your own.  To get started on that, just take the definition from my plugin and plop it into your controller, and then tweak it to directly reference your controller and model names (instead of the generated stuff from the plugin).  This is handy because then you can put in logging statements, or step through it in a debugger, or whatever will help you debug. 

If that's still not working, please do respond and let us know precisely what fails, and I'll see if I can't help you nail it.
