レールで確認やプレビューを実装する方法は？

Question

私のレールアプリからJSON APIを呼び出しています。ユーザーがフォームに名前を入力すると、JSON APIが呼び出され、名前に一致するものがあるかどうかがわかります。時にはその1つで、私はJSONで提供されるデータでエントリを作成します。しかし、ほとんどの場合、JSONには複数の結果があります。どのように実装するのですか？同じ名前の複数の結果が見つかりました。どちらをお探しですか？ユーザーは自分が意図していたものを選択し、データベースにエントリを作成します。

私はJSONをテストするための簡単なスクリプトを書いています。

data = JSON.load response 

if data['results'].empty? 
    #if the JSON data is empty 
    puts "There was no movie found. Did you spell the movie name correctly?" 
elsif data['results'].count > 1 
    #if JSON Data has more than one result 
    data['results'].each do |movie| 
    Movie::Movies << Movie.new(movie['id'], 
         movie['title'], 
         movie['release_year'], 
         (imdb_url + movie['imdb']).to_s, 
         movie['rating'], 
         movie['poster_120x171'], 
         movie['poster_240x342'], 
         movie['poster_400x570']) 
    end 
    Movie::Movies.each do |movie| 
     puts "#{movie.title} : #{movie.release_year}" 
    end 
else 
    #IF JSON has only one entry 
    movie = Movie.new(data['results'][0]['id'], 
         data['results'][0]['title'], 
         data['results'][0]['release_year'], 
         (imdb_url + data['results'][0]['imdb']).to_s, 
         data['results'][0]['rating'], 
         data['results'][0]['poster_120x171'], 
         data['results'][0]['poster_240x342'], 
         data['results'][0]['poster_400x570']) 
end 

ここに私のコントローラがあります。 JSONが提供するハッシュの最初のレコードしか処理できません。私は、複数の結果がある場合、状況をどのように処理するかについての手がかりはありません。私のフォームは私にエラーを与えていたので、私は再び@movie = Movie.newを呼び出すために持っていたアクションを作成中にも

def create 
     require 'rest_client' 
     require 'json' 
     imdb_url = 'http://www.imdb.com/title/' 
     movie_title = movie_params['title'].delete(' ') 
     response = RestClient.get "http://api-public.guidebox.com/v1.43/US/xxxxxxxxxxxxxxxx<api-key>/search/movie/title/#{movie_title}" 
     data = JSON.load response 
     @movie = Movie.new #i am doing this because my for was giving error. 
     if data['results'].empty? 
      flash[:alert] = "Did you spell the Title correctly? Or Maybe we could not find the movie you are looking for." 
      render 'new' 
     elsif data['results'].count > 2 
     #Display all results to the user for them to pick what they really intended and create an entry of whaterver they choose. 
     else 
      @movie = Movie.new(gb_id: data['results'][0]['id'], 
           title: data['results'][0]['title'], 
           release_year: data['results'][0]['release_year'], 
           imdb_link: (imdb_url + data['results'][0]['imdb']).to_s, 
           rating: data['results'][0]['rating'], 
           small_img: data['results'][0]['poster_120x171'], 
           med_img: data['results'][0]['poster_240x342'], 
           large_img: data['results'][0]['poster_400x570']) 
      if @movie.save 
       flash[:notice] = 'Movie has been successfully Added.' 
       redirect_to @movie 
      else 
       flash[:alert] = "Something went wrong. Please try again." 
       render 'new' 
      end 
     end 
    end

あなたは近いです。ユーザーが結果を曖昧さを排除することを可能にするために、else節にあるものに似ていますが、別のアクションを使用してループします。

# controller 
def create 
    #... 
    if data['results'].empty? 
       flash[:alert] = "Did you spell the Title correctly? Or Maybe we could not find the movie you are looking for." 
       render 'new' 
    elsif data['results'].count > 1 
    @movie_choices = [] 
    data['results'].each_with_index do |result, idx| 
     @movie_choices << Movie.new(gb_id: data['results'][idx]['id'], 
         title: data['results'][idx]['title'] #, ... 

    end 
    render 'movies/choose_movie' 
    else 
    @movie = Movie.new(gb_id: data['results'][0]['id'], 
         title: data['results'][0]['title'], 
         release_year: data['results'][0]['release_year'], 
         imdb_link: (imdb_url + data['results'][0]['imdb']).to_s, 
         rating: data['results'][0]['rating'], 
         small_img: data['results'][0]['poster_120x171'], 
         med_img: data['results'][0]['poster_240x342'], 
         large_img: data['results'][0]['poster_400x570']) 
    if @movie.save 
     flash[:notice] = 'Movie has been successfully Added.' 
     redirect_to @movie 
    else 
     flash[:alert] = "Something went wrong. Please try again." 
     render 'new' 
    end 
    end 
end 

def movie_chosen 
    chosen_movie_gb_id = params[:movie_gb_id] 
    @movie = Movie.new(gb_id: params[:movie_id], 
        title: params[:movie_title], 
        # ... 
        ) 
    if @movie.save 
     flash[:notice] = 'Movie has been successfully Added.' 
     redirect_to @movie 
    else 
     flash[:alert] = "Something went wrong. Please try again." 
     render 'new' 
    end 
end
