Question

my google pie chart code is

var data = google.visualization.arrayToDataTable([
          ['Task', 'Hours per Day'],
          ["Work",     50],
          ["Eat",      20],
          ["Commute",  20],
          ["Watch TV", 5],
          ["Sleep",    5]
        ]);

and my code is (<%= @datas.map { |d| [d.name, d.value] }.inspect %>)
which gives the result

([["apple", "10"], ["orange", 20], ["banana", 30], ["grapes", 80], ["papaya", 44]])

when i put this result in my google pie chart code directly like this

  var data = google.visualization.arrayToDataTable([["apple", "10"], ["orange", 20], ["banana", 30], ["grapes", 80], ["papaya", 44]])

then it works perfectly.
But keeping directly

var data = google.visualization.arrayToDataTable(<%= @datas.map { |d| [d.name, d.value] }.inspect %>)

does not work. What could be the reason behind this. Do ruby code have some formate to keep inside Or where i am doing wrong?

Answer 1

What about

(<%= @datas.map { |d| [d.name, d.value] }.to_json.html_safe -%>)
