Nested Resources and Routes

hi,

i have some nested resources like, a deal has_many :orders and has_one :invoice i am using nested routing for these. so the urls are like:

deals_url deal_orders_url deal_invoice_url

and others for the whole CRUD

although everything is working perfectly, the updates for a nested resource are stuck. e.g. the edit page for an order comes up, buts submitting it gives me an error:

Couldn't find Order without an ID
app/controllers/duties_controller.rb:92:in `get_order'

i have created a before_filter :get_deal

def get_deal @deal = Deal.find(params[:deal_id]) end

do i need to change something in my edit/update actions?? right now they are default ones generated after scaffolding.

Regards

You need to change the way you reference orders so that you scope an order within a deal.

Give this a shot and let me know if it works:

order_controller.rb:

Index action: @order = @deal.orders.find(:all)

Show action: @order = @deal.orders.find(params[:id])

New action: @order = @deal.orders.new

Edit action: @order = @deal.orders.find(params[:id])

Create action: @order = @deal.orders.new(params[:order])

Update action: @order = @deal.orders.find(params[:id])

Delete action: @order = @deal.orders.find(params[:id])
