用数字显示评级 - ratyrate gem

Question

我似乎可以弄清楚如何使用ratyrate gem来显示数字而不仅仅是星星。这是我的代码

Valuable | <%= @course.rates("valuable").count %> ratings : 
  <%= rating_for @course, "valuable", enable_half: true %> 

Fun | <%= @course.rates("fun").count %> ratings : 
  <%= rating_for @course, "fun", enable_half: true %>

Easiness | <%= @course.rates("easiness").count %> ratings  : 
  <%= rating_for @course, "easiness", enable_half: true %>

文档将此作为解决方案，但它对我不起作用

<%= rating_for @movie, "original_score", target: "#hintDiv", targetFormat: "Score: {score}" %>
