People,
I can order categories when looking at the categories list page but how
do I change the recipe page to list the categories in alpha order in the
recipe pull-down box?:
Category:
<% @categories.each do |category| %>
>
<%= category.name %>
<% end %>
Thanks,
Phil.

In your controller just modify the query that loads the @categories
variable to return the rows in the correct sort order.
Something like…
@categories = Categories.find(:all, :order=>“name”)
Philip,
Have a look at
http://blog.teksol.info/articles/2006/01/03/belongs_to-user-interface-take-ii
It shows you
- how to order, and also
- how to validate for presence
- how to highlight for validation error

in recipe_controller.rb:
def show
@recipe = Recipe.find(params[:id])
@categories_for_select = Category.find(:all, :order => “name”).collect
{
|c| [c.name, c.id] }
end
in show.rhtml:
<%= select “recipe”, “category_id”, @categories_for_select %>
the option that = @recipe.category_id will automatically be selected.
