I've decided using gem letsrate in my app, but I have some problem, probably caused by gem.
First some code:
I've got a model Article:
class Article < ActiveRecord::Base
letsrate_rateable "quality"
...
end
and model User (generated by Devise):
class User < ActiveRecord::Base
letsrate_rater
...
end
I've used generator according to readme instructions:
rails g letsrate user
Everything works great until I try destroy my article object, then I've got this error:
>> Article.last.destroy

The error occures no matter if I use quality dimension or not. I will be very grateful for your reply where the problem is.
PS. Im'using the newest version of gem (letsrate (1.0.7))
