I went throught the “agile web developemnt with rails” and Now I’m  
trying to ‘enhance’ the code with some extra options. When I go to  
admin/shipping I want to include some data from the products table in  
with the order info listed. I can’t seem to get this to work. in my  
partial form I’m trying to add this:

 \<%= order\_line.image\_url %\>

I’m recieving this error  
undefined method `image\_url’ for #Order:0xb77ee194

I call the partial with:

\<%= render(:partial =\> "order\_line", :collection =\> @pending\_orders) %\>

Here is how I get @pending\_orders  
@pending\_orders = Order.pending\_shipping

and finally my order class  
class Order \< ActiveRecord::Base

has\_many :line\_items

# function to retrieve all orders that haven’t been marked as shipped

yet.

# this allows us to see what orders have been made

def self.pending\_shipping  
find(:all, :conditions =\> “shipped\_at is null”)  
end

end

What do I need to do to get some product data into my shipping view?

Charlie,

Could be that image\_url is not known in the model for order\_line. I  
think it  
should be something like “order\_line.image\_url = product.image\_url”

Something similar is done in the books example webshop in  
models/line\_item.rb  
with: “item.unit\_price = product.price”

Hope it helps.

Gerard.

order\_line isn’t acutally a model. It is the name of the partial form.  
it holds the value @pending\_orders. I need to get data from the product  
table into @pending\_orders.

Charlie,

Mind you I’m a newbie so this discussion might end up beyond the scope  
of my  
knowledge. Nevertheless, digging back in the book, the data needs to be  
available in the controller (getting it from the model) when you want to  
display it in the view. Product info is available (in the admin  
controller)  
when generating the “orders pending” list. Have you simply tried  
“product.image\_url”.

Regards,

Gerard.

order\_line isn’t actually a model. it is the name of  
the partial form. Within that form order\_line holds  
the value of @pending\_orders. I need product info in  
pending orders.

Charlie,

When adding a line to “views/admin/\_order\_line.rhtml”  
(The one with \<\<\< behind it)

 \<% order\_line.line\_items.each do |li| %\> 
\<%= li.quantity %\>\<%= li.product.title %\>\<%= li.product.image\_url %\> \<\<\<\< 
 \<% end %\> 

It shows /images/picture.jpg in the html output. So when encapsulated in  
an  
 ![]() tag you should see a picture.

Is that’s what your looking for?

Regards,

Gerard.
