ruby inside javascript block [slim template]

Question

There is a way to put ruby conditions inside javascript block? i.e.

javascript:
  var config = {
      common_value_1 : 1, 
      common_value_2 : 2 
  };
           


        

Answer 1

You have 2 options:

1. Use a ruby section

This scenario is better for complex code.

I have a ruby object that I want to make a JSON. So, inside my slim file I'll create a ruby section:

ruby:

  myObject = @object.to_json.html_safe

Pay attention to html_safe: it's important to not escape double quotes.

Then you can use myObject inside javascript section:

javascript:

  var data = #{myObject};

2. Use double curly braces

For simple cases, use the double curly braces inside the javascript section, like stated in @fphilipe answer:

javascript:

  var data = #{{@object.to_json}};
