Hello everyone, While walking through AWDWR, Task D: Add a Dash of AJAX, I was initially unable to let the AJAX magic work. Hitting the Add to Cart button doesn''t yield to any output on its own; I had to manually refresh the pages to witness the change. But when I tried to restart the ruby server, and load the application again, everything worked fine. Any explanations to behavior mentioned above? Are there other instances in which you have to restart a ruby server?

Without knowing exactly what was happening its hard to say in your case.

Don''t know what exactly happened in that chapter/task D that you mention. But as a general rule you have to restart the server whenever you make changes to the config files or include a new plugin. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Thanks for the tips, I''ll keep those in mind. But I apparently did not
alter any configuration files while coding the cart application, so
its strikes me as odd that I had to restart the server in order to get
my application working well. I was unclear before, so let me try to
explain my situation more in detail.
I was working on section 9.2 of the book. It''s the part wherein you
modify the "Add to Cart" button to send an AJAX request instead of a
normal HTTP Post request, by adding this code to the index.rhtml view:
<% form_remote_tag :url => { :action => :add_to_cart, :id => product
}
do %>
<%= submit_tag "Add to Cart" %>
<% end %>
Then I followed these steps:
--> I enabled javascript libraries through the <%javascript_include_tag
:defaults %>
--> Then I disabled the browser refresh upon clicking the "Add to
Cart" button by stopping the page from redirecting to the index
display
--> Afterwards, I added app/views/store/add_to_cart.rjs with this
code "page.replace_html("cart" , :partial => "cart"
, :object =>
@cart)".
--> I saved everything, hit the refresh button on the browser, then
when i finally click on the "Add to Cart" button, nothing happens. The
cart display on the side bar ought to display the product that I''ve
chosen to add. Only after refreshing again do i see the cart updated
with the correct information. Of course, everything would eventually
work fine if i restart the server. But still, I wish to understand
this behavior to further understand the rails framework. Thanks! :)

And by the way, the development.log did report an error that shows
something like this:

Actually I''ve run into this issue before also, seems to be limited to js views used for ajax, where rails doesn''t seem to know its there until i restart the server. I have no idea why, and I have no idea under what conditions it happens, just wanted to say I''ve experienced it..

I see, my old version of rails is the culprit then. Thanks for that info. I didn''t download the latest version of rails before because I thought that it might have deprecated some of the Rails 1.2 syntax used in the book. I guess I should just give it a try then. :) On May 19, 10:07 am, "Ryan Bigg (Radar)" <radarliste...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> That''s very unusual to have to restart your server for it to detect a new > view file, especially if there was an action for it.

The older version of rails may not be the culprit, I never said it definitely was. I was just musing that you were using an older version of Rails.
