Best way to scope Statuses to User's friends?

Hey folks,

I've been trying to scope the status feed in statuses#index to show statuses from the current_user's friends.

I was able to create an array of current_user's friends called @contacts. @statuses = @contacts.statuses.all just leads to a NoMethodError for 'statuses' - so I'm wondering if I'm going to need to:

  1. Iterate the statuses for each user in the @contacts array
  2. Push those to another big array (@friends_statuses for example)
  3. Order them by :created_at
  4. Iterate each status from the new @friends_statuses array (in the view)

Can anybody think of a way that's a little more efficient?

Existing Statuses Controller

def index
@user_friendships = current_user.user_friendships.all

@user_friendships.each do |friendship|
  friend = friendship.friend
  @contacts ||= Array.new
  @contacts.push(friend)
end

 @statuses = Status.all

respond_to do |format|
  format.html # index.html.erb
  format.json { render json: @statuses }
end

Thanks!

Figured it out!

def index
  @user_friendships = current_user.user_friendships.all

  @user_friendships.each do |friendship|
    friend = friendship.friend
    @contacts ||= Array.new
    @contacts.push(friend)
  end

  @contacts.each do |x|
    x_statuses = x.statuses.all
      x.statuses.each do |stat|

     #   puts stat.activity  <- just to see things are going through

    @friend_statuses ||= Array.new
    @friend_statuses.push(stat)
    end
  end

    #   puts @friend_statuses

   @statuses = @friend_statuses

  respond_to do |format|
    format.html # index.html.erb
    format.json { render json: @statuses }
  end
end
