here is the rhtml that works:
<% if cart_item == @current_item %>
<tr id="current_item">
<% else %>
<tr>
<% end %>
<td><%= cart_item.quantity %>×</td>
<td><%= h(cart_item.title) %></td>
<td class="item-price"><%= number_to_currency(cart_item.price) %></
td>
<td>
<%= link_to_remote "-", {:url => { :action
=> :remove_from_cart, :id => cart_item.product}},
{ :href => url_for(:action => :remove_from_cart, :id =>
cart_item.product) } %>
<%= link_to_remote "+", {:url => { :action => :add_to_cart, :id
=> cart_item.product}},
{ :href => url_for(:action => :add_to_cart, :id =>
cart_item.product) } %>
</td>
</tr>
here is the rjs that works with the rhtml:
=begin
rjs doesn't give us the ability to generate JavaScript that tests
for divs. It does, however, let us iterate over elements on the page
that match
a certain CSS selector pattern.
=end
page.select("div#notice" ).each { |div| div.hide }
page.replace_html("cart", :partial => "cart", :object => @cart)
page.replace_html("flash_notice", "<div></div>")
#START_HIGHLIGHT
page[:cart].visual_effect :blind_down if @cart.total_items ==
1
#END_HIGHLIGHT
page[:current_item].visual_effect :highlight,
:startcolor => "#88ff88",
:endcolor => "#114411"
here is the haml:
- if cart_item == @current_item
%tr#current_item
- else
%tr
%td
= cart_item.quantity
×
%td
= h(cart_item.title)
%td{:class => 'item-price'}
= number_to_currency(cart_item.price)
%td
= link_to_remote "-", {:url => {:action
=> :remove_from_cart, :id => cart_item.product}}, {:href =>
url_for(:action => :remove_from_cart, :id => cart_item.product)}
= link_to_remote "+", {:url => {:action => :add_to_cart, :id =>
cart_item.product}}, {:href => url_for(:action => :add_to_cart, :id =>
cart_item.product)}
here is the 'section' in the nav (store.rhtml)
<% hidden_div_if(@cart.items.empty?, :id => "cart") do %>
<%= render(:partial => "cart", :object => @cart) %>
<% end %>
partial for the 'cart' (haml -- this renders and works with the rhtml
version of the + -)
%div{:class => 'cart-title'} Your Cart
%table
= render(:partial => "cart_item", :collection => cart.items)
%tr{:class => 'total-line'}
%td{:colspan => '2'} Total
%td{:class => 'total-cell'}
=number_to_currency(cart.total_price)
%td
- if @order.nil?
= button_to("Checkout" , :action => :checkout)
- form_remote_tag :url => { :action => :empty_cart } do
= submit_tag("Empty cart")

*********************************************************************************************************************
when running the rhtml and pressing the '+' or '-' in the window, it
will add the item (or remove) the item and inc/dec the item count. It
will then 'flash' to let the user 'know' something changed.
when I use the haml version, it executes, but the update will 'hide'
or change the view. If I 'refresh' the form, the items show up and
show up with the 'correct' values.
