ruby on rails - Show an object's rating with letsrate -

i'm creating music album review site, user posts album reviews (pins), , select 1-5 stars display on show page. i'm using letsrate gem , works fine input stars on form when submitting new pin , editing. need display input on show page.

when have <%= @pin.rates %> on show page, displays this: [#<rate id: 8, rater_id: 1, rateable_id: 36, rateable_type: "pin", stars: 4.0, dimension: nil, created_at: "2013-08-19 22:28:36", updated_at: "2013-08-19 22:28:36">]

i need stars: 4.0 display 4 stars. (and not allow them edited in show view)

this rate model:

class rate < activerecord::base   belongs_to :rater, :class_name => "user"   belongs_to :rateable, :polymorphic => true   belongs_to :pin    attr_accessible :rate, :dimension  end 

i saw question posted, doesn't explain how use helper: displaying individual user ratings (letsrate gem)

if use <%= rating_for @pin =>, stars show up, can rerate them, not good. need disable them.

any suggestions appreciated.

you can try:

<%= @pin.rates[:stars].to_i %>
