Finding a specific category

Rails
1

For the following controller:

thufir@arrakis ~/oreilly-recipes-categories $ cat app/controllers/
recipes_controller.rb -n | head -n 18 | tail -n 3
16 @recipe = Recipe.find(params[:id])
17 @categories= Category.find_all
18 end
thufir@arrakis ~/oreilly-recipes-categories $

http://oreilly-recipes-categories.googlecode.com/svn/trunk/app/
controllers/recipes_controller.rb

I just want to pull up the Category instance which belongs to this
Recipe
instance. What should be on line 17 for that, please?

thanks,

Thufir

@recipe.categories or @recipe.category depending on whether it’s a
belongs_to or a has_many.

And then in the view (show), basically, the @category instance can be
used just as the @recipe instance is used?

thufir@arrakis ~/oreilly-recipes-categories $ cat app/controllers/
recipes_controller.rb -n | head -n 18 | tail -n 4
15 def show
16 @recipe = Recipe.find(params[:id])
17 @category = @recipe.category
18 end
thufir@arrakis ~/oreilly-recipes-categories $ cat app/models/recipe.rb
class Recipe < ActiveRecord::Base
belongs_to :category
end
thufir@arrakis ~/oreilly-recipes-categories $

thanks,
