I need to get multiple complex sets of data into Javascript

Question

So I have a database that I'm trying to display reports on using the Highcharts javascript library.

The issue is i have no idea how to effectively get this data from Rails into Javascript.

Simply using html data attributes doesnt scale because i have many charts and many different sets of data for each one. I need to exclude certain columns, join tables, etc.

Any ideas?

有几种选择：

1. 使用 gon
创建实例变量并将其传递到html模板

1. 使用ActiveModelSerializers创建端点并格式化数据，例如：https://www.engineyard.com/blog/active-model-serializers

2. 您可以创建一个 jbuilder 视图，并通过javascript ajax调用调用的端点呈现它

最低功耗 Gon ，但您发送到其中的所有内容都可在HTML源代码中查看。
