Displaying Star Image According Integer In Database

I have a star ratings feature. And pretty much, I would like it to display a particular image depending on the number.

Here's some pseduo code I would like to do in my review.rb model

def show_stars
  if rating = 1
    display 1star.png
  elsif rating = 2
    display 2star.png
  elsif rating = 3
    display 3star.png
  elsif rating = 4
    display 4star.png
  elsif rating = 5
    display 5star.png
end

How would I make this code work? And also, how would I make it display right in a view file?

This should really go into a view helper.

def show_stars(review)
  image_tag "#{review.rating}star.png"
end

Then in your view:

<%= show_stars @review %>
