我想要这种格式的结果
data: [{"label":"present","value":35},
{"label":"absent","value":50},
{"label":"leave","value":45},
{"label":"performance","value":67}]
我确实尝试过这段代码
data: <%= @orders.map { |d| {label: d.shipping, value: d.price}}.to_json.html_safe -%>
这给出了结果
data: [{"label":"present","value":"35"},
{"label":"absent","value":"50"},
{"label":"leave","value":"45"},
{"label":"performance","value":"67"}]
这里的问题是在第一个标签中我以这种格式获得值“35”，但我只需要没有“”的值 35。我怎么能得到这个？我在@orders 中的数据是
[#<Order id: 8, price: "35", purchased_at: "2012-01"
