Rails - Jan 2006 - Cookbook recipes eg - ordering categories in the recipe pull-down box

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?:

>   <p><b>Category:</b><br>
>   <select name="recipe[category_id]">
>    <% @categories.each do |category| %>
>        <option value="<%= category.id %>"
>          <%= '' selected'' if category.id ==
@recipe.category_id %>>
>          <%= category.name %>
>        </option>
>    <% end %>
>   </select></p>

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.
