Hello-
I have a form that I''m using form_for on to bind the form to my order
object. Within the form, I want to select a product (each order has
one product, which makes this easy). In my order and product models,
an order belongs_to a product. I didn''t specify that a product
has_many orders (although I did test that the problem still exists
even if I do specify that). Here''s the code I''m using to
generate the
select list:
@packages = Package.find(:all, :order => ''name'') #this is
in my
controller
<%= f.collection_select :product, @products, :id, :name, { :prompt =>
''--select one--''} %>
The call to collection_select creates the list of options just fine,
but if my order has a value set for product, it doesn''t get set as the
selected value.
I''ve tried a slew of other variations on the call to collection_select
(e.g., using :product_id instead of :product) and all seem to fail.
Does anyone know what I might be doing wrong?
Regards,
Eric

One more thing. I debugged my app and when I inspect my @order object, the product field is being correctly set. I debugged a little deeper and it looks like at some point, Rails is trying to decide to set a particular option to selected by evaluating something like the following (assuming product id 7 was selected): "7" == 7 It looks like, for the purpose of setting my model''s attributes, the product id is being turned into an integer, but for selecting a value in collection_select, it is keeping it a string. Very confusing. -Eric On Jan 2, 2:56 am, emarthinsen <emarthin...-wDk3GJWIFSIagCBP5wnx4wC/G2K4zDHf@public.gmane.org> wrote:> Hello- > > I have a form that I''m using form_for on to bind the form to my order > object.

Ah ha, I figured it out. In my migration, I had accidentally specified that the product_id column should be a string, instead of an integer. Once I changed the type, everything worked great.
