Sorting posts based on the most liked in Rails

I am trying to have two tabs, one for the most recent posts and the other is for the most liked posts. However, I am really stuck of how to get my post sorted by the most liked(voted). I did use acts_as_votable gem to get the voting system part into the website. I am new to Rails, let me know if what more details do you need to help out,thanks.

You should enable Caching. These columns will automatically be updated after each vote.

Create new migration rails g migration add_cached_votes_to_posts and add below code:

class AddCachedVotesToPosts < ActiveRecord::Migration
  def self.up
    add_column :posts, :cached_votes_total, :integer, :default => 0
    add_column :posts, :cached_votes_score, :integer, :default => 0
    add_column :posts, :cached_votes_up, :integer, :default => 0
    add_column :posts, :cached_votes_down, :integer, :default => 0
    add_column :posts, :cached_weighted_score, :integer, :default => 0
    add_column :posts, :cached_weighted_total, :integer, :default => 0
    add_column :posts, :cached_weighted_average, :float, :default => 0.0
    add_index  :posts, :cached_votes_total
    add_index  :posts, :cached_votes_score
    add_index  :posts, :cached_votes_up
    add_index  :posts, :cached_votes_down
    add_index  :posts, :cached_weighted_score
    add_index  :posts, :cached_weighted_total
    add_index  :posts, :cached_weighted_average

    # Uncomment this line to force caching of existing votes
    # Post.find_each(&:update_cached_votes)
  end

  def self.down
    remove_column :posts, :cached_votes_total
    remove_column :posts, :cached_votes_score
    remove_column :posts, :cached_votes_up
    remove_column :posts, :cached_votes_down
    remove_column :posts, :cached_weighted_score
    remove_column :posts, :cached_weighted_total
    remove_column :posts, :cached_weighted_average
  end
end

Run migration command rake db:migrate

And use the cached column for ordering:

Post.order(cached_votes_score: :desc)
