在Ruby中建模复杂的JSON
我有一段JSON，它是NBA比赛的boxscore，如下例所示。是否有任何策略可以将这些数据转换成一个健全的Ruby模型（可能使用序列化器）？当我从远程API中提取这些数据时，这个JSON中有很多嵌套的数据，例如个人玩家统计、团队统计、团队数据等。最好使用sane Ruby建模工具来处理这个JSON。没关系，但我将尝试将此建模应用到ruby gem中，而不是rails应用程序中 下面是我正在处理的一个JSON blob示例：在Ruby中建模复杂的JSON,ruby,json,rubygems,Ruby,Json,Rubygems,我有一段JSON，它是NBA比赛的boxscore，如下例所示。是否有任何策略可以将这些数据转换成一个健全的Ruby模型（可能使用序列化器）？当我从远程API中提取这些数据时，这个JSON中有很多嵌套的数据，例如个人玩家统计、团队统计、团队数据等。最好使用sane Ruby建模工具来处理这个JSON。没关系，但我将尝试将此建模应用到ruby gem中，而不是rails应用程序中 下面是我正在处理的一个JSON blob示例： [ { "game_length": "2:38",

我必须将您的JSON复制到一个文件中才能正确读取它（注意，这不是必需的，您可以将JSON流直接提供给
JSON.parsea.each { |x| p x.methods(false) };
[:game_length, :game_length=, :location, :location=, :game_time, :game_time=, :season_type, :season_type=, :game_id, :game_id=, :scores_by_quarter, :scores_by_quarter=, :team_stats, :team_stats=, :away_team_final_score, :away_team_final_score=, :quarter, :quarter=, :game_date, :game_date=, :technicals, :technicals=, :sport, :sport=, :visiting_team, :visiting_team=, :status, :status=, :home_team_id, :home_team_id=, :title, :title=, :attendance, :attendance=, :home_team_final_score, :home_team_final_score=, :updated_at, :updated_at=, :visiting_team_id, :visiting_team_id=, :home_team, :home_team=, :season_year, :season_year=, :officials, :officials=]
您可以将JSON数据解析为两个类：数组和哈希：
- 阵列：
data = [1, 2] data.to_json # => "[1,2]" JSON.parse(data.to_json) # => [1, 2] - 散列：
data = {'a' => 1} data.to_json # => "{\"a\":1}" JSON.parse(data.to_json) # => {"a"=>1}
data
返回包含数据的哈希，在您的示例中，该哈希就是所有数据。如果存在多个散列，则使用以下方法对其进行迭代：data。首先
或：data.each { |hash| ... }
data.first['scores_by_quarter'].last['scores']['home_team_score']
# => 4
减少数据大小。扔掉这么大的样品没什么好处，除非你想让人们的眼睛发晕。
data.map { |hash| ... }
data.first['scores_by_quarter'].last['scores']['home_team_score']
# => 4
