Passing quantity in a shopping cart
I am using this line on my index.rhtml page to capture the quantity
required of a particular item for a basic shopping cart app:
<%= text_field ''line_item'', ''quantity'', {:size=>3} %> </td>
but my next screen (a cart screen) doesn''t reflect what was entered in
that text field when the item is added to the cart. That is,

update or alter cart
I want to modify and update the items in the Depot - "display_cart".
Since the cart is in a session, its a little hard to get at the data.
I just want to create a way to change quantities, prices and
recalculate.
Has someone done this, and could you point me to the right direction.
Thanks
Chas

One To Many To Many
Hey all,
I''m trying to find a simple way to reference all of the objects that
belong to their parent''s parent. In other words:
Clients --> Orders --> LineItems
How do I get all of a client''s lineitems in one array (i.e.,
client.all_lineitems)?
Thanks!

Stuck on ActiveRecord
Hi,
I''m having great fun developing with Rails but I''ve come to a problem
that I can''t quite figure out.
I have an Order object that "has_many" order_lines. This works perfectly
and I can see all the lines.
The OrderLine object has an order_id field as well as product_id and
amount.
Now ideally I would want to do :
order.orderline[0].product.name

Foreign Key naming convention override
I am working with an existing database and have to keep all table and
field names as they are. ''tblcustomers'' and ''tblitems'' are linked by the

is called ''txtcustomerid''.

Cannot see what I have done wrong.
In the Agile Rails tutorial I am revisiting building a cart. I have
followed the steps given in the book to create the class ''Cart''
thus:
class Cart
attr_reader :items
attr_reader :total_price
def add_product(product)
@items << LineItem.for_product(product)
@total_price += product.price
end
def initialize
@items = []
@total_price = 0.0

Agile Depot Tutorial Help
anyone can explain me why in the Agile Depot Tutorial application they
use i.product_id
to find if a product already exist in the cart, because the cart
contains items, each of them references a product.
I tried i.product_id like in the tutorial
and
i.product.i
all of these 2 notation works , but i find the second seems more
clean??? isn''t it.
Any explanation will be fine

Using ''validates_inclusion_of'' to validate foreign key
I seem to be missing something trying to use ''validates_inclusion_of'' to
validate a foreign key and was hoping some one could piont out my
mistake?
The problem seems to be that Order.find_all.collect is not returning an
array that contains the order_id, if I replace it with a hardcoded array
everything works as expected.

Hi..Guys new plugin again
Hi..
Guys new plugin again
Foreign Key Associations is a plugin that automatically creates
associations based on foreign-keys. The associations are created at
runtime-ie. as your ActiveRecord models are loaded-so they will always
be up-to-date.
For example, given a foreign-key from a customer_id column in an
orders table to an id column in a customers table, the plugin
creates:

Question about using DISTINCT in ActiveRecord find method.
Hi,
Am relatively new to the RoR world. My question is quite simple.
I have a query like such:
shipmentNumbers = Order.find_by_sql(["select distinct s.id from orders
o, line_items li, shipment_lines sl, shipments s where o.number=? and
o.id = li.order_id and li.id = sl.line_item_id and sl.shipment_id =
s.id", number])
The above query works fine. I wanted to do the same query using
