Parameterizing auto-completion?

rubyonrails-talk
1

Is there a way to pass in a parameter (e.g. an ID) to the auto_complete_for... method? I have a table of answers that I'm serving up for auto-completion, but I only want the answers that apply to a given field. In my answers table, each entry has an list ID, and I would like to be able to to just get the answers that match the ID for a particular list.

I've overridden the auto_complete_for.... for method to specify my own :conditions parameter, but so far I'm hard-coding the answer list ID. What I'd really like to do is, perhaps in the rhtml, specify an ID parameter that then somehow the auto_complete_for... would be able to access. Is there a way to do that?

Thanks,    --Paul

I found a solution, which I will share for the other newbies out there. It turns out that you can specify an :id parameter for the URL you are accessing for the autocompletion by doing this in your view:

<%= text_field_with_auto_complete :answer, :answer_text, {},   {url=>{:action=>'auto_complete_for_answer_answer_text', :id=>23} }%>

Here the :action is set to my auto_complete_for method, and the id is the ID of the list whose options I want to use for auto-completion. In my controller, the auto_complete_for_answer_answer_text can access the ID as params[:id].

Hi

I am using Ajax.Updater and I am having a bit of a problem with Prototype. I am trying to use a sortable list (from scriptaculous) and so I want using ajax do some server logic.

Problem is that the list never show the correct array on the server side. So I looked at the javascript (you can see the code lower that works...)

When I look at the Sortable.serialize('list'); it show correctly list=1&list=4&list=3

So I would expect the ajax request to look as a get

myurl/?list=1&list=4&list=3 but instead show a weird querystring

myurl/?list%5B%5D=3&_=

So looks like when the param are serialized in the Ajax object itself is screwed up. I have a work around but wonder if someone else had the same problem.. Also the dev.rubyonrails.com is down so I cannot post/look up bugs

following is my javascript code that works but I had to set the parameters to false and append my querystring to the URL to fix it.....

<script type="text/javascript"> // <![CDATA[ Sortable.create('list', {onUpdate:function(){      var params = Sortable.serialize('list');      //BUG in prototype. Element with name do no get serialized correctly...      new Ajax.Updater('list-info', '<%= path %>' + '?' + params, {          method: 'get',          onComplete:function(request){              new Effect.Highlight('list',{});          }, parameters: false          , evalScripts:false, asynchronous:true        }      )    } } )

  // ]]> </script>
