I''ve found quite a few posts on the subject, but no satisfactory
answers. Maybe Rails just doesn''t support this yet.
How do I create a url with a named RESTful route that also has
parameters?
I want to write this:
link_to_remote "Show Details", {:url => item_url(@item, :details
=>
1), :method => :get}
And get this:
<a href="#" onclick="new
Ajax.Request(''http://localhost/items/1?
detail=1'', {asynchronous:true, evalScripts:true,
method:''get''});
return false;">Show Detail</a>
Instead I get:
You have a nil object when you didn''t expect it!
The error occurred while evaluating nil.to_sym
/usr/local/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/
active_support/core_ext/hash/keys.rb:27:in `symbolize_keys''

helpers/url_helper.rb:21:in `url_for''
(eval):19:in `item_url''
My best workaround has been to do:
link_to_remote "Show Details", {:url => item_url(@item) + "?
detail=1", :method => :get}
Which doesn''t seem like the Rails way.
I''m not using a route like: items/1;detail and a helper like:
detail_item_url(@item), because I have mutliple parameters which I can
mix and match to change the view. It creates too many custom named
routes.
Thanks,
Ryan
