Question

Hi so im trying to display a star rating on the website so far i’ve got the ratings in a form of a number however i want to times that number and display the equall amount of stars using a loop or somehting alike i.e. if the rating is 4 then 4 star pictures get printed out, any ideas?

my code so far…

number_with_precision(product.no_of_stars, :precision => 1) // this line prints out the number ans works just fine

im trying to do something like this…

product.no_of_stars.times do |i|
image_tag(“/images/star.jpg”)
end

but it keeps saying “undefined method `times’ for #”

Answer 1

I think it’s because your product.no_of_stars is returning a float, whereas only Integers (or perhaps Fixnums) can respond to times; if you’re happy with ignoring any fractions, you could try:

product.no_of_stars.to_i.times do ...

Or if you always want an integer, then perhaps change your DB to use an integer column?

Otherwise it might work better to use javascript for your star rating; a quick google will give you plenty of results.
