Problem accessing item using has many through

Rails
1

My models are

class BakeryOutput < ActiveRecord::Base
belongs_to :recipe
belongs_to :customer
end

class Recipe < ActiveRecord::Base
has_many :ingredient_recipes
has_many :ingredients, :through => :ingredient_recipes
has_many :bakery_outputs
validates_presence_of :name
validates_uniqueness_of :name
end

class IngredientRecipe < ActiveRecord::Base
belongs_to :ingredient
belongs_to :recipe
end

class Ingredient < ActiveRecord::Base
has_many :ingredient_recipes
has_many :recipes, :through => :ingredient_recipes
validates_presence_of :name
validates_uniqueness_of :name
end

and in my controller for the show method

def show
@bakery_output = BakeryOutput.find(params[:id], :include =>
[:recipe, :customer])
@recipe = Recipe.find(:all, :conditions => [“id = ?”,
@bakery_output.recipe_id])
@ingredients=Recipe.ingredients

respond_to do |format|
  format.html # show.rhtml
  format.xml  { render :xml => @ingredients.to_xml }
end

end

In the controller the first two statement work ok but the third
@ingredients=Recipe.ingredients
generates an error

“undefined method `ingredients’ for Recipe:Class”

I’m trying to collect all the ingredients in a recipe

Can someone tell me where I am going wrong, this is my first app.

regards
Martin

It should be @recipe.ingredients

just spotted the other problem: @recipe isn’t a single @recipe as I
expected, but an array of recipes.

Fred

So how do I need to write it please
