nil değeri form değeri yerine

Question

Beer Receipe sayfalık bir sayfam var. rails c'a bir çift ekledim ve Beer Receipe sayfasında iyi görünüyor. Ancak, formun kendisinde derecelendirmeyi oluşturmaya çalıştığımda, hem yıldız hem de yorum formda boş görünüyor ve raylara c baktığımda nil değerini gösteriyor. Niye ya? Beer_Receipe, Bileşen, & Puanlama Bu şema olduğunu

:

create_table "beer_receipes", force: :cascade do |t| 
    t.string "name" 
    t.string "style" 
    t.datetime "created_at", null: false 
    t.datetime "updated_at", null: false 
    end 

    create_table "ingredients", force: :cascade do |t| 
    t.string "name" 
    t.string "category" 
    t.datetime "created_at", null: false 
    t.datetime "updated_at", null: false 
    end 

    create_table "ratings", force: :cascade do |t| 
    t.string "ratable_type" 
    t.integer "ratable_id" 
    t.integer "stars" 
    t.text  "comments" 
    t.datetime "created_at", null: false 
    t.datetime "updated_at", null: false 
    end 

Onların dernekler

şunlardır:

class BeerReceipe < ActiveRecord::Base 
    has_many :ratings, as: :ratable, dependent: :destroy 
end 

class Ingredient < ActiveRecord::Base 
    has_many :ratings, as: :ratable, dependent: :destroy 
end 

class Rating < ActiveRecord::Base 
    belongs_to :ratable, polymorphic: true 
end

eylem oluşturmak derecelendirmelerinizin denetleyicisi bu deneyin _form.html.erb sayfa

<%= form_for([@beer_receipe, @beer_receipe.ratings.build]) do |f| %> 
    <p> 
     <%= f.label :stars %><br> 
     <%= f.select :stars, (0..10) %> 
    </p> 
    <p> 
     <%= f.label :comments %><br> 
     <%= f.text_field :comments %> 
    </p> 
    <p> 
     <%= f.submit %> 
    </p> 
    <% end %> 

Ve son olarak, ama en az, Puanlar Kontrolör geçerli:

@rating = Rating.new(stars: params[:rating][:star], comments: params[:rating][:comments], ratable_id: params[:beer_recipe_id]) 

if @rating.save 
    puts "huzzah!" 
end 

Bu işe yararsa bana bildirin.
