私はRailsの4.2.6があり、2.3をルビー、

：

Routing Error uninitialized constant FavoriteSongsController 

favorite_songs_Controller.rb

class FavoriteSongsController < ApplicationController 
    before_action :set_song 

    def create 
    if Favorite.create(favorited: @fav_song, user: current_user) 
     flash[:success] = t('favorite_song.success') 
     redirect_to :back 
    else 
     flash[:danger] = t('favorite_song.wrong') 
     redirect_to :back 
    end 
    end 

    def destroy 
    Favorite.where(favorited_id: @fav_song.id, user_id: current_user.id).first.destroy 
    flash[:info] = t('favorite_song.destroy') 
    redirect_to :back 
    end 

    private 

    def set_song 
    @fav_song = Song.find(params[:song_id] || params[:id]) 
    end 
end 

routes.rbを

songs_controller.rb

class SongsController < ApplicationController 
    def show 
    @artist = Artist.friendly.find(params[:artist_id]) 
    @song = @artist.songs.find(params[:id]) 
    end 
end 

song.rb

class Song < ActiveRecord::Base 
    include PgSearch 


    belongs_to :artist 
    default_scope -> { order(:title) } 

    validates :artist_id, presence: true 
    validates :title,  presence: true, 
        length: { maximum: 140 } 


    has_attached_file :mp3, 
    :url => "/songs/:artist_slug/:song_slug_:hash.:extension" 
    validates_attachment :mp3, 
    :content_type => { :content_type => ["audio/mpeg", "audio/mp3"] }, 
    :file_name => { :matches => [/mp3\Z/] } 
    validates_attachment_presence :mp3 
    validates_attachment_size :mp3, { less_than: 15.megabytes } 

    Paperclip.interpolates :artist_slug do |attachment, style| 
    attachment.instance.artist.slug 
    end 

    Paperclip.interpolates :song_slug do |attachment, style| 
    attachment.instance.slug 
    end 

    Paperclip::Attachment.default_options.update({ 
    :hash_secret => "jHLi3fdrmHZQ8r9wxGZbyyGzc9BT8UAxOk2q6O1T1ut+pgmDqmtFIdaBuw8tkhAK0nhDMrCQYCMfOXiUH3R27zG22OHi0852jK93/TaiDtymwzPXZQOxhM6KR6aODhEK+LmqYG1uIGHvqfzD1BOh/R7JuvW2cf+0dT0V3hiFEzA=" 
    }) 

    pg_search_scope :search_by_title, 
        :against => :title, 
        :using => { 
         :trigram => { 
         :threshold => 0.1 
         } 
        } 

    def slug=(value) 
    if value.present? 
     write_attribute(:slug, value) 
     end 
    end 

end 

user.rb

class User < ActiveRecord::Base 
    authenticates_with_sorcery! 

    has_many :favorites 
    has_many :favorite_songs, through: :favorites, source: :favorited, source_type: 'Song' 

    validates :email,     presence: true, length: { maximum: 255 }, 
             email_format: { message: I18n.t('signup.email_invalid') }, 
             uniqueness: { case_sensitive: false } 

    validates :password,     presence: true, confirmation: true, length: { minimum: 6} 


end 

favorite.rb

class Favorite < ActiveRecord::Base 
    belongs_to :favorited, polymorphic: true 
    belongs_to :user 
end 

私は様々なtututorialsを見て、数多くの提案に従ってもできるように思えてきましたいけないの

Rails.application.routes.draw do 

    mount RailsAdmin::Engine => '/admin', as: 'rails_admin' 
    root 'home#index' 
    get 'search', to: 'search#search' 


    resources :users, only: [:index, :show, :edit, :update] 
    get '/signup', to: 'users#new' 
    post '/signup', to: 'users#create' 


    get '/login', to: 'sessions#new' 
    post '/login', to: 'sessions#create' 
    get '/logout', to: 'sessions#destroy' 

    resources :reset_passwords, only: [:new, :create, :update, :edit] 


    resources :artists, :path => "/", only: [:show] do 
    resources :songs, :path => "/", only: [:show] 
    end 

    resources :favorite_songs, only: [:create, :destroy] 
end 

歌/ songs.html.erb

<%= render 'favorite_songs/fav' %> 

favorite_songs/_fav.html.erb

<% if logged_in? %> 
    <%- unless current_user.favorites.exists?(id: @song.id) -%> 
     <%= link_to 'Add to favorites', favorite_songs_path(song_id: @song), method: :post %> 
    <%- else -%> 
     <%= link_to 'Remove from favorites', favorite_song_path(@song), method: :delete %> 
    <%- end -%> 
<% end %> 

自分で問題を解決する

Answer 1

名ためアプリ/フォルダ内のfavorite_songs_Controller.rbファイルだけでなく、他のファイルには、あまりにもそれを修正、および/または他のファイルしてください、downcasedする必要があります。

Answer 2

あなたのお気に入りのコントローラはfavorite_songs_Controller.rbです。 Rubyは命名規則に準拠していないファイル内のクラスを自動的に見つけることができません。代わりにfavorite_songs_controller.rbを使用してください。名前には小文字の「C」があります（controller）。それが問題の原因です。それを変えて、あなたはすばらしいはずです。
