API種子檔案可以訪問哈希中的專案，但是在創建方法時它會給出空陣列-有解無憂

我有一個 api 請求，我在其中獲取每部電影的提供者資料。我對其進行迭代，當我執行 provider['provider_name'] 時，它會為我提供每部電影的提供者串列，這很棒。一旦我將它放入 Content.create 方法中，它就會給出 nil。如果我在 create 方法中移動整個每個陳述句，我最終只會得到完整的哈希/陣列。不知道該去哪里。

movie_url = 'https://api.themoviedb.org/3/trending/movie/week?api_key=API_KEY&language=en-US'
2.times do |m|
  contents = JSON.parse(URI.open("#{movie_url}&page=#{m   1}").read)['results']
  contents.each do |content|
    base_poster_url = 'https://image.tmdb.org/t/p/original'

    results = JSON.parse(URI.open("https://api.themoviedb.org/3/movie/#{content['id']}/watch/providers?api_key=API_KEY&language=en-US&watch_region=GB").read)['results']

    if results != {} && results["GB"] && results['GB']["flatrate"]
      results['GB']['flatrate'].each do |provider|
        p provider["provider_name"]

        Content.create(
          imdb_id: content['id'],
          title: content['original_title'],
          description: content['overview'],
          poster: "#{base_poster_url}#{content['poster_path']}",
          rating: content['vote_average'],
          content_type: content['media_type'],
          streaming_services: nil
        )
      end
      puts "content created for movie: #{content['original_title']}"
    end
  end
end

p provider["provider_name]in 終端的輸出如下所示：

content created for movie: Chip 'n Dale: Rescue Rangers
"Sky Go"
"Now TV Cinema"
"Virgin TV Go"
content created for movie: Top Gun
"Virgin TV Go"
content created for movie: Uncharted
"Virgin TV Go"

如果我provider[provider_name"]像這樣移動到 Content.create 方法中

streaming_services: provider["provider_name"]

資料庫輸出如下所示：

content_type: "movie",
streaming_services: []

api 請求檔案如下所示

  },
}

不確定我做錯了什么，并嘗試使用 map、split、flatten 以幾種不同的方式訪問它。有時會取得小小的成功。.split(",") 實際上給了我陣列，但是每部電影只有一個陣列，有些有多個提供者。我相信有更好的方法。

uj5u.com熱心網友回復：

我想你需要Content像這樣將創建移出回圈：

movie_url = 'https://api.themoviedb.org/3/trending/movie/week?api_key=API_KEY&language=en-US'
2.times do |m|
  contents = JSON.parse(URI.open("#{movie_url}&page=#{m   1}").read)['results']
  contents.each do |content|
    base_poster_url = 'https://image.tmdb.org/t/p/original'

    results = JSON.parse(URI.open("https://api.themoviedb.org/3/movie/#{content['id']}/watch/providers?api_key=API_KEY&language=en-US&watch_region=GB").read)['results']

    Content.create(
      imdb_id: content['id'],
      title: content['original_title'],
      description: content['overview'],
      poster: "#{base_poster_url}#{content['poster_path']}",
      rating: content['vote_average'],
      content_type: content['media_type'],
      streaming_services: results.dig("GB", "flatrate")&.map { |provider| provider["provider_name"] }
    )
  end
end

注意：如果streaming_services型別是陣列，則保持原樣。如果是字串，則join(', ')在最后添加streaming_services: results.dig("GB", "flatrate")&.map { |provider| provider["provider_name"] }&.join(', ')
