Forum: Ruby on Rails Rails 3 link_to :remote

I recently moved to Rails 3 and am still getting used to some of its new
ways of working.

I have the following code:

----

<%= link_to "#{order.name}", :url => {:controller => 'orders', :action
=> 'show', :id => order.id }, :update => "order_div", :method => 'get',
:remote => true %>

----

I know I'm probably just missing something simple, but I'm not sure what
it is. I have my javascript included in the application.html.erb file.

This code (excluding the :remote => true) works under Rails 2.3.8 when
using link_to remote. I don't know what the new arguments require. And
after searching around for exactly what I want this to do, I couldn't
find anything.

All I want it to do is show the order information in a DIV I named:
order_div

So instead of the 'show' action moving me to the /orders/show/etc... I
want it to display the info that show normally would in the same page. I
have a list of orders to click on. Want this to happen without a full
page refresh.

Can anyone help me with the new way Rails handles this sort of thing?

Thanks,

I wasn't sure if this was the right way to accomplish this:

----

format.js {
  render :update do |page|
    page.replace_html 'order_div', :partial => 'show_order'
  end
}

----

Apperently not, as it doesn't work. But can someone at least tell me if 
I am on the right track? I've checked everywhere I can think of for a 
solution to this. If anyone has any other resources to check out, please 
let me know.

Sorry, forgot to say that this is in my index action of my orders 
controller. Thanks.

Update for anyone that needs help in this area. I found my problem. You 
might have to do the same (if you are using this function the way I am).

In my controller, I don't know why I put this in the Index action 
before. It is now in the SHOW (duh) action:

----
format.js {
  render(:update) {|page| page.replace_html 'order_div', :partial => 
'orders/order_show'}
}
----

I took out all of the other junk in my "link_to" in the view and only 
have this now:

----
<%= link_to "#{order.name}", order, :remote => true %>
----

So I have a list of orders in a column on the left side of the screen. 
There is a right border separating it and the right column. When I click 
on one of the orders, it shows the order info in the right column. 
Exactly what I wanted. Piece of cake now that I think about it.

Enjoy!
