copied!<p>You seem to be mixing up stuff.</p> <p>You have html inside your controller-method? That should be in your view. For each controller-method, normally a view with the same name is rendered, except if you explicitly call <code>render</code> from within your controller-method.</p> <p>You do not write html in your controller. You write html in the view, and sometimes you have helpers to make your views more readable.</p> <p>Secondly, in your first piece of code, which is some view-code, i hope. The view is prepared at server-side and then sent to the client. You can render another view, a partial, from a view. But this does not load data live.</p> <p>How i would fix this. Inside your views where you want to dynamically render the validation:</p> <pre><code><script> $("#validate_company").live("keyup", function() { $("#company_info").load("<%= url_for :controller => 'live_validations', :action => 'validate_client_company' %>"); }); </script> </code></pre> <p>Then inside your controller you write:</p> <pre><code>class LiveValidationsController < ApplicationController def validate_client_company if params[:first_name].length > 0 @client = Client.find_by_company(params[:company]) @error = @client.nil? ? :valid_username : :invalid_username else @error = nil end render :partial => "message", :layout => false end end </code></pre> <p>Inside your <code>app/helper/live_validations_helper.rb</code> you add a method</p> <pre><code>def get_validation_message(error) if error == :invalid_username image_tag('/images/cancel_48.png', :alt => 'Invalid Username') + "Name taken" elsif error == :valid_username image_tag('/images/accepted_48.png', :alt => 'Valid Username') end end </code></pre> <p>and inside your <code>message</code> view you write something like:</p> <pre><code><%= get_validation_message(@error) %> </code></pre>
