Hello, I am new to AJAX and need help displaying a shopping cart using  
Ajax. I can display the cart in the sidebar fine if I just redirect to  
the same page, but the wanted to use AJAX to do this.  
I am getting some sort of a error message when I click the add to order  
button.

View :  
\<% form\_remote\_tag :url =\> { :action =\> ‘add\_to\_cart’ } do %\>  
\<%= submit\_tag “Add to Order” %\>  
\<% end %\>

Controller:  
def add\_to\_order  
@cart = find\_cart  
@cart.add\_order(@new\_order\_item)  
respond\_to do |format|  
format.js  
end

File: add\_to\_order.js.rjs:  
page.replace\_html(“leftnav” , :partial =\> “cart\_partial”, :object =\>  
@cart)

I tried running the code in both internet explorer and firefox. In  
internet explorer when i click add to order, I get a file download  
dialog which asks me to save or find an unknown file.  
In firefox however, I get this message:

Hi Carter Smith

Can you please paste the view code and the relevant controller code ?  
You are specifying action as ‘add\_to\_cart’ But given action is  
‘add\_to\_order’  
And one more thing This type of error normally happens when  
trying to use double update That is at the view side and controller side

Sorry the action should be ‘add\_to\_order’, it was a typo. But the  
problem still persists.  
My code:  
Class: index.html.erb:

```
<% for product in @products -%>

```

\<% form\_tag :action =\> ‘add\_to\_order’ do %\>

## \<%=h product.name %\>
  
\<%= hidden\_field\_tag ‘product\_id’, product.id %\>  
**Size:**   
\<%= select(“product”, “size\_id”, product.productsizes.collect {|c|  
[c.size.to\_s + ’ ’ + number\_to\_currency(c.price).to\_s, c.id] }) %\>  
**Quantity:**  
\<%= select ‘product’, ‘quantity’, @quantity, :include\_blank =\> false  
%\>  

\<% form\_remote\_tag :url =\> { :action =\> ‘add\_to\_order’ } do %\>  
\<%= submit\_tag “Add to Order” %\>  
\<% end %\>  
\<% end %\>

### \<%= flash[:notice] %\>

## Welcome:&nbsp;\<%= current\_user.login %\>
 \<%= render(:partial =\> "cart\_partial", :object =\> @cart)%\> - Logout

Class: order\_controller.rb:

class OrderController \< ApplicationController  
def index  
@cart = find\_cart  
end

def add\_to\_order  
@new\_order\_item = Orderitem.new  
@new\_order\_item.product = Product.find(params[:product\_id])  
@new\_order\_item.quantity = params[:product][:quantity]  
@new\_order\_item.size = Productsize.find(params[:product][:size\_id])

```
    @cart = find_cart
    @cart.add_order(@new_order_item)
    respond_to do |format|

```

format.js  
end  
end

def empty\_cart  
session[:cart] = nil  
flash[:notice] = “Your cart is currently empty”  
redirect\_to :action =\> ‘index’  
end

private

def find\_cart  
session[:cart] ||= Cart.new  
end

end

Class: add\_to\_order.js.rjs:  
page.replace\_html(“leftnav” , :partial =\> “cart\_partial”, :object =\>  
@cart)

Class: \_cart\_partial.html.erb:

**Your Order:**

* * *
  
\<% for orderitems in @cart.orderitems %\>  
\<%=h orderitems.quantity %\>  
\<%=h orderitems.product.name %\>  
\<%=h orderitems.size.size %\>  
\<% end %\>

**Please Specify Pickup Date and Time:**  
\<% form\_for :user do |f| %\>  
\<%= f.datetime\_select :created\_at, :twelve\_hour =\> true, :default  
=\> Time.now, :start\_year =\> Time.now.year %\>  
\<% end %\>  
\<%= button\_to ‘Empty cart’, :action =\> ‘empty\_cart’ %\>

Hi Carter Smith

```
Sorry I was on leave two days. Is it solved? I see there is some 

```

problem in your view side code. You are defining form\_remote\_tag inside  
form\_tag Why? And when you click AddToOrder which is supposed to trigger  
an ajax action wont pass any params to action ‘add\_to\_order’ .

Sijo, thank you very much. You solved my problem. The problem was  
exactly what you mentioned above.
