hotel_users_controller, sessions_controller in hotel directory like

Hello Thani,
I tried that, but no luck. The edit link that goes with delete link
works fine. It is shown below:
= link_to 'Edit', :controller => controller_name, :action => 'edit', :id
=> rec.id
Corresponding routes.rb file snippet is shown below:

Rail3 Arel finders are just great, but you can't find a lot of example
on how powerful they really are.
I made a discovery, just experimenting with some chaining.
List say you have
Foo has may Bars

"campaign"}, :with => "'val='+value", :method => :post %>

The rails.js UJS file appears to handle only links/anchors or forms.
I went through a "I want to do this with UJS" about a week ago. While
I got it to work, I am not sure what I accomplished since I was not

I am trying to test the 'type' attribute' of some elements in my
page , but I don't get it right,

t = e.readAttribute('type')
page.alert(t)
end
just displays :
[object HTMLInputElement]

Thanks Greg
I've already look at it.
My issue was related to the remote_function which seems to be still
available...
All that stuff in Rails 3 is not yet so clear for me...
