javascript - JSON 对象到 Rails 对象

Question

我使用 JSON.stringify(object) 在 html View 中创建一个 JSON 对象，它输出以下 JSON 对象

{
 "0X1W6": "{\"type\":\"Hourly\",\"hr\":\"12\",\"min\":\"30\",\"every_hr\":\"5\"}",
  "Tk18f": "{\"type\":\"Daily\",\"hr\":\"12\",\"min\":\"30\",\"days_checked\":[1,4]}"
}

如何将其转换为 ruby​​ 对象，如下所示:

[
  { :type => 'Hourly', :hr => 12, :min => 30, :every_hr => 5}
  { :type => 'Daily', :hr => 12, :min => 30, :days_checked => [1,4]}
]

Answer 1

result = []

z = ActiveSupport::JSON.decode( '{
  "0X1W6": "{\"type\":\"Hourly\",\"hr\":\"12\",\"min\":\"30\",\"every_hr\":\"5\"}",
  "Tk18f": "{\"type\":\"Daily\",\"hr\":\"12\",\"min\":\"30\",\"days_checked\":[1,4]}"
}')

z.each_value do|i|
  x = {}
  ActiveSupport::JSON.decode(i).each{|k,v|
    x[k.to_sym] = (v.class == String && v.to_i.to_s == v) ? v.to_i : v
  }
  result << x
end
