Ruby on Rails图像循环

Question

I'm attempting to create a loop which shows stars as reviews are placed for a product, i have it so that it shows the rating as a number however i wish for it to display an image relating to the rating number,

i've currently got

<%=product.no_of_stars.to_i do image_tag "star-on.png" end %> 

however it just displays the rating figure and not the number, no doubt I've missed something simple.

I've researched other questions and they state that should be enough for what i want, but of course its not working as expected.

Thanks, Ben.

Answer 1

Try this.

<%=product.no_of_stars.to_i.times do image_tag "star-on.png" end %> 

You are missing the times method. This is what allows you to run the number as a loop over and over again (super simplification).

Answer 2

The above answer is not quite correct. The problem is that Integer#times returns the integer it was called on, so you will still get 5 as the result. Try

<% product.no_of_starts.to_i.times do %>
  <%= image_tag "star-on.png" %>
<% end %>
