Question

我试图将一对数据结构中包含的数据转换为与HighCharts（A JS Chart Library）兼容的格式。通过解析JSON文件来填充初始数据结构。（我不能改变这一步，而必须使用生成的数据结构）初始数据结构如下所示：

初始化：

@areaBreakdown = Hash.new { |hash, key| hash[key] = Hash.new } 
@deptBreakdown = Hash.new { |hash, key| hash[key] = Hash.new }

示例数据@areaBreakdown：

{#<Area id: 1, area_code: "123", created_at: "2014-04-04 20:23:11",
updated_at: "2014-04-04 20:23:11", name: "testarea1",
org_code: "123456">=>{"areaScore"=>46.65},
#<Area id: 2, area_code: "456", created_at: "2014-04-04 20:23:11",
updated_at: "2014-04-04 20:23:11", name: "testarea2",
org_code: "123456">=>{"areaScore"=>52.98}}

示例数据@deptBreakdown：

{#<Dept id: 1, dept_code: "78910", created_at: "2014-04-04 20:23:11",
updated_at: "2014-04-04 20:23:11", name: "testdeptunderarea1",
area_id: 1>=>{"deptScore"=>46.65},
#<Dept id: 2, dept_code: "4567", created_at: "2014-04-04 20:23:11",
updated_at: "2014-04-04 20:23:11", name: "testdept1underarea2",
area_id: 2>=>{"deptScore"=>49.81},
#<Dept id: 3, dept_code: "99999", created_at: "2014-04-04 20:23:11",
updated_at: "2014-04-04 20:23:11", name: "testdept2underarea2",
area_id: 2>=>{"deptScore"=>56.15}}

Highchart为我正在尝试构建的图表采用两个独立的数据结构。必须将 areaBreakdown 转换为哈希数组，每个索引对应不同的区域。数组名称是 areaScores 。

areaScores的硬编码版本：

@hardCodedAreaScores = Array.new
# Push a Hash onto the array
@hardCodedAreaScores.push Hash.new
# Access the newly pushed hash by giving it a key, value pair to add
@hardCodedAreaScores[0]["name"] = "area1"
# Do it again
@hardCodedAreaScores[0]["drilldown"] = "area1"
# And again
@hardCodedAreaScores[0]["y"] = 35.15

@hardCodedAreaScores.push Hash.new
@hardCodedAreaScores[1]["name"] = "area2"
@hardCodedAreaScores[1]["drilldown"] = "area2"
@hardCodedAreaScores[1]["y"] = 45.59

@deptBreakdown ， deptScores 的转换应该是一个哈希数组。每个哈希应该有3个键：＆＃34; name＆＃34;，＆＃34; id＆＃34;和＆＃34; data＆＃34;。＆＃34;名称＆＃34; =＆＃34; id＆＃34; =＆＃34;钻取＆＃34;。数据是一个数组数组，用于保存要显示的图表的数据点。例如，＆＃34;数据＆＃34; = [[x1，y1]，[x2，y2]]。

deptScores的硬编码示例：

@hardCodedDepartmentScores = Array.new
@hardCodedDepartmentScores.push Hash.new
@hardCodedDepartmentScores[0]["name"] = "area1"
@hardCodedDepartmentScores[0]["id"] = "area1"
@hardCodedDepartmentScores[0]["data"] = Array.new
@hardCodedDepartmentScores[0]["data"][0] = Array.new
@hardCodedDepartmentScores[0]["data"][0].push "Department1UnderArea1"
@hardCodedDepartmentScores[0]["data"][0].push 20.15
@hardCodedDepartmentScores[0]["data"].push Array.new
@hardCodedDepartmentScores[0]["data"][1].push "Department2UnderArea1"
@hardCodedDepartmentScores[0]["data"][1].push 69.69
@hardCodedDepartmentScores.push Hash.new
@hardCodedDepartmentScores[1]["name"] = "area2"
@hardCodedDepartmentScores[1]["id"] = "area2"
@hardCodedDepartmentScores[1]["data"] = Array.new
@hardCodedDepartmentScores[1]["data"][0] = Array.new
@hardCodedDepartmentScores[1]["data"][0].push "Department1UnderArea2"
@hardCodedDepartmentScores[1]["data"][0].push 98.21
@hardCodedDepartmentScores[1]["data"].push Array.new
@hardCodedDepartmentScores[1]["data"][1].push "Department2UnderArea2"
@hardCodedDepartmentScores[1]["data"][1].push 12.34

我的尝试：

def cycleThroughProcessedDataAndCreateHighChartsDataSetsBreakdown(areaBreakdown, deptBreakdown, employBreakdown)
areaScores = Array.new
areaScores.push Hash.new
deptScores = Array.new
deptScores.push Hash.new
counter = 0
deptCounter = 0
areaCounter = 0

  areaBreakdown.each_key do |area|
   areaScores.push Hash.new
   areaScores[counter]["name"] = areaBreakdown[area]["name"]
   areaScores[counter]["drilldown"] = areaBreakdown[area]["name"]
   areaScores[counter]["areaScore"] = areaBreakdown[area]["areaScore"]

   deptScores.push Hash.new
   deptScores[areaCounter]["name"] = areaBreakdown[area]["name"]
   deptScores[areaCounter]["id"] = areaBreakdown[area]["name"]


   deptBreakdown.each_key do |dept|
    if deptScores[counter]["area_id"] == areaBreakdown[area]["area_id"]
      deptScores[counter]["data"] = Array.new
      deptScores[counter]["data"][deptCounter] = Array.new
      deptScores[counter]["data"][deptCounter].push deptBreakdown[dept]["name"]
      deptScores[counter]["data"][deptCounter].push deptBreakdown[dept]["deptScore"]

      deptCounter += 1
    end     
  #areaCounter += 1
  end
counter += 1
end
debugger

return deptScores, areaScores
end

我的问题是如何将两个初始数据结构（或两个硬编码版本）正确转换为所需的数据结构。我对ruby有点新，我无法访问某些信息，如姓名和身份证。在尝试迭代并填写各种数据结构时，我也遇到了许多空方法错误。必须进行迭代，因为 @areBreakdown 和 @deptBreakdown 的大小是动态的。如何正确填充 @areaScores 和 @deptScores 两个数据结构？

谢谢，马特

P.S。我为这篇长篇大论道歉。任何帮助表示赞赏。如果问题不清楚，将提供进一步的细节。

当前输出：

(rdb:1) areaScores
[{"name"=>nil, "drilldown"=>nil, "areaScore"=>46.65}, {"name"=>nil, "drilldown"=>nil, "areaScore"=>52.98}]

(rdb:1) deptScores
[{"name"=>nil, "id"=>nil, "data"=>[nil, nil, [nil, 56.15]]}, {"data"=>[nil, nil, nil, nil, nil, [nil, 56.15]]}, {}]

Answer 1

我终于弄清楚了我的问题。在设置名称和ID时，我没有正确访问哈希。我在下面提供了我的解决方案：

<强>解决方案：

areaScores = Array.new  
deptScores = Array.new
counter = 0

areaBreakdown.each_key do |area|
  deptCounter = 0
  areaScores.push Hash.new
  areaScores[counter]["name"] = area["name"]
  areaScores[counter]["drilldown"] = area["name"]
  areaScores[counter]["y"] = areaBreakdown[area]["areaScore"]

  deptScores.push Hash.new
  deptScores[counter]["name"] = area["name"]
  deptScores[counter]["id"] = area["name"]
  deptScores[counter]["data"] = Array.new

  deptBreakdown.each_key do |dept|
    if dept["area_id"] == area["id"] #if department belongs to area 
      deptScores[counter]["data"][deptCounter] = Array.new
      deptScores[counter]["data"][deptCounter].push dept["name"]
      deptScores[counter]["data"][deptCounter].push deptBreakdown[dept]["deptScore"]
      deptCounter += 1
    end #if     
  end #deptBreakdown
  counter += 1
end #areaBreakdown
#debugger
return deptScores, areaScores

感谢您的帮助！
