私はグラフの作成にFusion Chartsという宝石を使用していますが、指示はコントローラの中で私が望む以上のものです。未定義のメソッド `keys 'が配列の宝石ロジックを取り除こうとしています
ここで動作する呼び出しです。ここで
weights_over_time = []
weights.each do |weight|
weights_over_time.push({
label: weight.created_at.strftime("%m-%-d-%y"),
value: weight.weight,
})
end
@weights_chart = Fusioncharts::Chart.new({
type: 'line',
renderAt: 'chart-container',
width: '400',
height: '300',
dataFormat: 'json',
dataSource: {
"chart": {
"caption": "Weight over time",
"xAxisName": "Date",
"yAxisName": "Weight",
"lineThickness": "2",
"paletteColors": "#0075c2",
"baseFontColor": "#333333",
"baseFont": "Helvetica Neue,Arial",
"captionFontSize": "14",
"subcaptionFontSize": "14",
"subcaptionFontBold": "0",
"showBorder": "0",
"bgColor": "#ffffff",
"showShadow": "0",
"canvasBgColor": "#ffffff",
"canvasBorderAlpha": "0",
"divlineAlpha": "100",
"divlineColor": "#999999",
"divlineThickness": "1",
"divLineIsDashed": "1",
"divLineDashLen": "1",
"divLineGapLen": "1",
"showXAxisLine": "1",
"xAxisLineThickness": "1",
"xAxisLineColor": "#999999",
"showAlternateHGridColor": "0"
},
data: weights_over_time
}
})
end
がモデルにこれのほとんどを置くために私の試みで、これは配列のための未定義のメソッドkeys」になります。ダイナミックデータで静的なすべてのjsonを引数として初期化できるかどうかはわかりました。配列をハッシュ[*配列]でハッシュ化しようとしましたが、ハッシュの引数が奇数になります。
class Example
class Fusioncharts::Chart
def initialize(weights_over_time)
self.chart {
type: 'area2d',
renderAt: 'chart-container',
width: '400',
height: '300',
dataFormat: 'json',
dataSource: {
"chart": {
"caption": "Weight over time",
"xAxisName": "Date",
"yAxisName": "Weight",
"paletteColors": "#0075c2",
"bgColor": "#ffffff",
"showBorder": "0",
"showCanvasBorder": "0",
"plotBorderAlpha": "10",
"usePlotGradientColor": "0",
"plotFillAlpha": "50",
"showXAxisLine": "1",
"axisLineAlpha": "25",
"divLineAlpha": "10",
"showValues": "1",
"showAlternateHGridColor": "0",
"captionFontSize": "14",
"subcaptionFontSize": "14",
"subcaptionFontBold": "0",
"toolTipColor": "#ffffff",
"toolTipBorderThickness": "0",
"toolTipBgColor": "#000000",
"toolTipBgAlpha": "80",
"toolTipBorderRadius": "2",
"toolTipPadding": "5"
},
data: weights_over_time
}
}
end
end
end
class ExamplesController < ApplicationController
def fc_json
@user = current_user
@weights = @user.weights.all
weights = @weights.select(:weight, :created_at)
weights_over_time = []
weights.each do |weight|
weights_over_time.push(
weights: {
x: weight.created_at,
y: weight.weight
}
)
end
@chart = Fusioncharts::Chart.new(weights_over_time)
end
end
私は確かにそれをより読みやすく/採用のベストプラクティスを作るためにあらゆる批判を歓迎するが、私はほとんどが私のコントローラ内でこのすべてを持っていない気に。

NoMethodError行をハイライト＃
ため 未定義のメソッド `キー
@chart = FusionChartsの:: Chart.new（weights_over_time）
