Hi everyone,  
I have been introduced to ruby on rails a couple of days ago and it  
really brings out the fun in programming for the Web. I’m trying to  
implement a text\_field\_with\_auto\_complete as described in  
[script.aculo.us](http://script.aculo.us) , as follows:

controller:  
class SearchController \< ApplicationController  
auto\_complete\_for :recipe, :name  
end

search.rhtml:

\<%= javascript\_include\_tag :defaults %\> \<%= text\_field\_with\_auto\_complete :recipe, :name %\>

The result, however, is an unresponsive site, with the following output  
from LightHTTPd:

Processing SearchController#auto\_complete\_for\_recipe\_recipe\_name (for  
127.0.0.1 at 2006-06-25 18:56:27) [POST]

Parameters: {“action”=\>“auto\_complete\_for\_recipe\_recipe\_name”,  
“controller”=\>“search”, “recipe”=\>{“recipe\_name”=\>“u”}}

Any ideas on what could be wrong? I tried a Recipe.search on the console  
but it gives me the same error.  
My database has a ‘recipes’ table with an id and a name string.

Thanks in advance,  
Ricardo
