Question

I have a page that has several “Feeds”. In my controller I have something like this:

def index

 @plays = current_user.plays.includes(:game).order("created_at desc")

 @wants = current_user.wants.includes(:game).order("created_at desc")

 @ratings = current_user.ratings.includes(:game).order("created_at desc") 

end

and I use code like this in the view:

   <% @plays.each do |play| %>
          You played <%= play.game.name %></p>
   <% end %>

Now I want to make a forth feed on the page that is “all activity” which displays Plays, Wants and Ratings in one feed sorted by created date (desc).

Any help on the best way to do this would be great.

UPDATE: As requested code from each model, nice and simple right now:

class Play < ActiveRecord::Base
  attr_accessible :game_id, :user_id, :description

  belongs_to :user
  belongs_to :game

end

class Rating < ActiveRecord::Base

  attr_accessible :game_id, :id, :score, :user_id, :description

  belongs_to :user
  belongs_to :game


end

class Want < ActiveRecord::Base
  attr_accessible :game_id, :user_id, :description

  belongs_to :user
  belongs_to :game


end

Since these come from separate tables, you won’t be able to sort them in the database query. But since you already have each of the arrays, you can use Ruby to combine and sort:

@activities = (@plays + @wants + @ratings).sort_by {|a| a.created_at}.reverse
