Processing by EquipmentController#show as */*

I'm getting this response when I send a jquery get request to render the show page for a piece of equipment - or any other show page for any object in the rails app for that matter (customer, warranty, etc)

I am using a select_tag to find the id of the item in question

<%= select_tag( "equip_id", options_from_collection_for_select(@equipment, :id, :equip_id, (@equipment_id.nil?) ? nil : @equipment_id), {:class => 'equipTag'}) %>

and am seeing that the app is getting the proper id - using alert - see the code below. However, when the server responds to the request, I get Processing by EquipmentController#show as */* ** instead of **Processing by EquipmentController#show as HTML which I receive if I use a link to show in a table lising of the equipment items or enter the id manually in the browser address bar - /equipment/4567 for example

javascript code -

$(document).on('change', '.equipTag', function(){

    var equipId = $(this).val();
    alert (equipId);
    $.get('/equipment/' + equipId);

});

I'd appreciate any help. Thanks in advance. John

Jay, That was very helpful - thanks for the lead on the redirect.

I have adapted the code in that post to my needs and it is working. Thanks so much! 

<% @custPath = {"Select"=>""} %>
<% @customers.each do |customer| %>
  <% @addPath = {customer.last_name + ", " + customer.first_name => customer_path(customer.id)} %>
  <% @custPath.merge!(@addPath) %>
<% end %> 

<%= select_tag :show_item, options_for_select(@custPath)%>

<script type="text/javascript">
      $('#show_item').change(function() {
      window.location = $(this).find('option:selected').val();
      });
 </script>

Now I have to figure out how to make the select tag look through the selection by an input other than a single letter. In other words, if I have customers Able and Adams, when I type ad, the program goes to the first "d" customer (Davidson) not the first "ad" customer (Adams) - do you have any ideas on that?

Hmm, for me, Chrome usually goes on to select subsequent letters in a dropdown as long as you don't pause too long when typing. That may be Chrome-specific, though, and it's not a very user-friendly solution regardless.

What most users would expect is probably an auto-complete field. It's a bit advanced, but here's a resource that might help.

It looks like you're using the jQuery get function, which does send a request that Rails responds to. But the response goes to a jQuery handler function; it isn't loaded as the new page content. So the way things are set up now, your browser simply discards the Rails response.

What you probably want to do instead is perform a redirect by setting window.location.
