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

–  
Sahil

thank for the suggestion Richard… but i managed to do it by adding  
an :except clause to the before filter to work on only new and edit

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])
