Rails 3, acts-as-taggable-on gem - how to get the most used tags?

Question

I use acts-as-taggable-on gem and would like to fetch 5 most used tags, how could I fetch them?

Answer 1

I think that your controller must be:

class PostController < ApplicationController
    def tag_cloud
        @tags = Post.tag_counts_on(:tags).limit(5).order('count desc')
    end
end
