JSON parsing error with erb on Ruby on Rails

Question

I'm trying to be able to have acess to a JSON file in a script tag in a .erb file which is a view for my Rails project.

I have this in my controller:

@myJSON = JSON(IO.binread("./path/to/file.json"));

And I have tried this in the view file:

<%= javascript_tag do %>
    var thing = <%= @myJSON %>;
<% end %>

But it gives me a SyntaxError in the console SyntaxError: expected property name, got '&', which is pretty obvious because the output in the code is something like:

var thing = [{"sigla"=>"AC", "nome"=>"Acre", "cidades"=>["Rio Branco", ...]}]

What am I getting wrong?

Answer 1

Try this in javascript_tag:

var thing = <%= @myJSON.to_json.html_safe %>;
