Obeserve_field on ruby on rails

Question

I want a search field to start outputting results once a user statrs typing

Here is what I got so far

 <%= observe_field 'keyword', :frequency => 0.5,
 :update => 'results',
 :loading => "Element.show('spinner')",
 :complete => "Element.hide('spinner')",
 :url => { :action=> 'search_results' } %>

then in my controller this is what i got. The text field is within a form i dont know if that makes a difference.

 def search_results
       keyword = params[:keyword]
       @tutors = Tutors.find(:all,:conditions => ["category LIKE ?", '%' + keyword + '%'])    
  end

Answer 1

If I understand your question correctly your action is not receiving the keyword as expected. Is this right? If so then it's because you need to add a :with argument to your observe_field call. Like this:

<%= observe_field 'keyword', 
    :frequency => 0.5,
    :update => 'results',
    :loading => "Element.show('spinner')",
    :complete => "Element.hide('spinner')",
    :url => { :action=> 'search_results' },
    :with => 'keyword' %>
