Rails - Dec 2005 - Rails: Select and html forms

I''m close to getting this to work, but not quite there.  I''m
trying to
implement a dropdown control, with the current choice selected.
I have the following code in the view:

      5 <select id="product_product_type"
name="product[product_type]">
      6 <%      7   types = ProductType.find(:all, :order =>
"product_type")
      8   options_from_collection_for_select( types, :id, :product_type, 
selected=@product_type_id)
      9 %>
     10 </select

Which renders the following:

<label for="product_product_type">Product
type</label><br/>
<select id="product_product_type"
name="product[product_type]">
<option value="2"></option>
...
<option value="6"
selected="selected">Supplies</option>
</select>


However, in the browser the "Supplies" item isn''t displaed on
load, but
the blank first option is.  Anyone see what I''m doing wrong?

This works, it''s probably not the best implementation...but it works.

http://wiki.rubyonrails.com/rails/pages/HowtoUseFormOptionHelpers

look for the section called ''A collection_select like helper'' 
I copied
that code into application_helper.rb and then used his view 
implementation.  Worked for me, although I had to change the last part 
in the view from :

@page.section_id

to just

page.section_id


Hopefully this will get you going.  Later.

Try this:

<%= collection_select(:product, :product_type, types, :id,
:product_type, { :include_blank => true }) %>

It works fine for me.
