Can anyone help with the following? I've been trying to follow along with the tutorial for making a real-time search box with Ajax (http://wiki.rubyonrails.org/rails/pages/How+to+make+a+real-time+search+box+with+the+Ajax+helpers), but have been hitting some snags along the way:
In the index view: <input id="search" name="search" type="text" value=""> <%= observe_field 'search', :frequency => 0.5, :update => 'searchresults', :url => { :controller => 'contacts', :action=> 'list' }, :with => "'search=' + escape(value)" %>
<div id="searchresults">
</div>
In the contacts controller
def list if @params['search'] @contacts_pages, @contacts = paginate :contacts, :order_by => 'firstname', :conditions => [ 'LOWER(firstname) LIKE ?', '%' + @params['search'].downcase + '%' ], :per_page => 20 @mark_term = @params['search'] render_without_layout else @contacts_pages, @contacts = paginate :contacts, :order_by => 'firstname', :per_page => 20 end end
And then finally in the list view.
<%= @mark_term ? highlight(contact.firstname, @mark_term) : h(contact.firstname) %>
Everytime I run it, the searchresults layer updates to show a error that isn't that helpful:
NoMethodError in ContactsController#list
You have a nil object when you didn't expect it! You might have expected an instance of ActiveRecord::Base. The error occurred while evaluating nil.
