我想在视图文件夹中使用CoffeeScript。由于我的视图文件夹中有一个部分文件_test.html.erb，如下所示：
<canvas id="doughnutChart" width="250" height="250"></canvas>
<script type="text/javascript">
var doughnut = document.getElementById("doughnutChart").getContext("2d");
var dchart = new Chart(doughnut, {
type: 'doughnut',
data: {
},
options:{
}
});
</script>
现在我想把CoffeeScript放在这里，我该怎么做。
谢谢
