Hi all,
Suppose I have a PurchaseItem model which refers to Product model…
class Product < ActiveRecord::Base
has_many :purchase_items
end
class PurchaseItem < ActiveRecord::Base
belongs_to :product
end
To keep things simple, one of the attribute of the Product model is
title.
On the interface, I have a textfield that I need to bind with
@purchase_item.product.title .
text_field ‘purchase_item’, ‘product.title’ doesn’t work for me.
How to achieve this using Rails 1.1.4? Does this feature exist by
default in Edge?
Oh and one more thing, will it matter if the attribute is an
ActiveRecord object or a value object like Money?
Thank you very much.
Regards,
John.

Add to the PurchaseItem model methods:
def product_title
product.title
end
def product_title= (t)
product.title = t
end
Then you can use
text_field ‘purchase_item’, ‘product_title’

Of course I can do that. I was doing exactly that way before I made
my post.
However, I feel that it’s kind of a messy hack.
Are you sure there is no ‘better’ solution?
Thanks anyway
Best regards,
John
