Hi, 1st of all, my english is bad, and i''m new to RoR, so accept my apologies from start. I need two combo-boxes populated from two tables that will act as filters for a product list. I''ve already read some examples and tutorials, but it seems that I''m still stuck in the problem. Files : db/migrate/001_create_products.rb http://pastie.textmate.org/60449 db/migrate/002_create_parent_categories.rb http://pastie.textmate.org/60452 db/migrate/003_create_categories.rb http://pastie.textmate.org/60453 app/controllers/admin_product_controller.rb http://pastie.textmate.org/60456 app/views/admin_product/list.rhtml http://pastie.textmate.org/60458 the Controller for Products is called admin_product. the list method takes all the products from the db_table called products and displays them. the trick is to have two combo-boxes, 1st populated with the parent_category_name from the parent_categories table, and the second populated with category_name from the categories table. the default value in the combo-boxes should be "- Select a parent category -" and " - Select a category -". When a option from the combo boxes is selected, the page should reload, displaying only the products that have the parent_category_id or the category_id that was selected. and also, if a parent_category is selected, the second combo box shoul display only the categories with the parent_category_id that was selected in the first combo-box. I think that the ajax example with state/county/city it''s not suitable, beacause the products list might be paginated. If I''m wrong please correct me. Thank you for spendig this much time reading all this stuff and also for any hints and code snippets that I can use.

Hi,
I''ve wrote in the list.rhtml this piece of code
<% collection_select(:categories, :id, @categories, :id,
:category_name,
options = {:prompt => ''- Select Parent Category
-''},
html_options = {:onChange => "remote_function :url =>
{:controller => ''admin_product'', :action =>
''list''}, :with =>
''Form.Element.serialize(this)''"})
%>
but it''s not working. Any ideas ?
1st of all, prompt should put ''- Select Parent Category -'' in
the
options, and it''s not working,
2nd of all, if i do collection_select(:categories, :category_name,
@categories, :id, :category_name,
it says
undefined method `category_name'' for #<Array:0x3525f8c>
I''ve got 2 days now sience i''m stuck with this problem at my
diploma
project.
All my respect,
Cezar
