ruby-on-rails - 向 Ruby JSON 对象添加值

Question

我正在研究 Ruby on Rails。我的数据库中有这样的 JSON 对象:

{"data":[
    {"name":"A", "available":"1"},
    {"name":"B", "available":"0"}
]}

我想通过添加另一条记录来更新它，它应该如下所示:

{"data":[
        {"name":"A", "available":"1"},
        {"name":"B", "available":"0"},
        {"name":"C","available":"1"}
    ]}

我该怎么做？

Answer 1

你可以试试这个

json = { "data" => [
         {"name" => "A", "available" => "1"},
         {"name" => "B", "available" => "0"}
       ]}
json["data"].push({"name" => "C", "available" => "1"})
