将 ruby​​ 哈希格式化为 json

Question

我目前正在将一些数据从 ruby​​ 格式化为 json； 我当前的代码如下所示

def line_chart_data
    @sources = ['Facebook','Twitter','Instagram','LinkedIn']
    @sourceCount = [5,12,16,6]
    @weeks = ['one','two','three','four','five','six']

    h = []
    @weeks.each do |i,v|
        h.push({'v' => 'Week ' + i})
        @sourceCount.each do |s|
             h.push({'v' => s})
        end
    end
    c = {c: h}


    #How the data should be formatted on export
    @sources2 = {
      cols: [
        {label: 'Week', type: 'string'},
        #Each Source needs to be looped though and formatted
        {label: 'Facebook', type: 'number'},
        {label: 'Twitter', type: 'number'},
        {label: 'Instagram', type: 'number'},
        {label: 'LinkedIn', type: 'number'}
      ],
      rows: c
     }



    respond_to do |format|
        format.js {render json: @sources2}
    end
end

当数据打印到控制台时，它看起来像这样（为简洁起见，稍微缩短了一点）

"rows":{"c":[{"v":"Week one"},{"v":5},{"v":12},{"v":16},{"v":6},
{"v":"Week two"},{"v":5},{"v":12},{"v":16},{"v":6},
{"v":"Week three"},{"v":5},{"v":12},{"v":16},{"v":6}]}

如果您注意到第一个“c”以数组开头，但在循环上述代码时，它不会每周创建一个新数组。代码应该看起来更像这样。

"rows":{"c":[{"v":"Week one"},{"v":5},{"v":12},{"v":16},{"v":6}],
{"c":[{"v":"Week two"},{"v":5},{"v":12},{"v":16},{"v":6}]},
{"c":[{"v":"Week three"},{"v":5},{"v":12},{"v":16},{"v":6}]}

每周数组的每个循环都会创建一个新的散列，其中键为“c”，值为数组。

非常感谢任何为我指明正确方向的帮助！卡在这上面好久了。

您需要重新编写代码才能获得此信息。你想要的 JSON 实际上是无效的，所以这是你能得到的最接近的：

"rows":[{"c":[{"v":"Week one"},{"v":5},{"v":12},{"v":16},{"v":6}],
{"c":[{"v":"Week two"},{"v":5},{"v":12},{"v":16},{"v":6}]},
{"c":[{"v":"Week three"},{"v":5},{"v":12},{"v":16},{"v":6}]}]

代码：

rows = []
@weeks.each do |i,v|
    h = []
    h.push({'v' => 'Week ' + i})
    @sourceCount.each do |s|
         h.push({'v' => s})
    end
    rows.push({"c" => h})
end



#How the data should be formatted on export
@sources2 = {
  cols: [
    {label: 'Week', type: 'string'},
    #Each Source needs to be looped though and formatted
    {label: 'Facebook', type: 'number'},
    {label: 'Twitter', type: 'number'},
    {label: 'Instagram', type: 'number'},
    {label: 'LinkedIn', type: 'number'}
  ],
  rows: rows
 }
