How to pass Ruby variables to a JavaScript function in a Rails view?

Question

I\'m wondering what the best practice is for passing variables to JavaScript functions in a rails view. Right now I\'m doing something like:

<% content_f         


        

Answer 1

- content_for :javascripts_vars do
  = "var costs_data = #{@records[:cost_mode][:data].to_json}".html_safe
  = "var graph_data = #{@records[:cost_mode][:graph].to_json}".html_safe
