Ruby Flickr API and Photosets

Question

I'm retrieving a list of an individual's photosets(albums) from flickr. How can I extract the id's from this array of hashes and then use flickr.photosets.getPhotos to list the images in each album? I'm still learning Ruby and feeling very stuck on this. I'm grateful for any push in the right direction.

When I try adding set.each do .. anything to the @photosets block - I get a no method error for 'each'.

photos_controller.rb

require 'flickraw'

class PhotosController < ApplicationController

  def index
    FlickRaw.api_key = ENV['FlickRaw_api_key']
    FlickRaw.shared_secret = ENV['FlickRaw_shared_secret']

    @photosets = flickr.photosets.getList(user_id: '67921947@N02').each do |set|
       set
    end
  end
end

photos/index.html.erb

<h1>Listing photosets</h1>

<%= @photosets %>

The current output

Listing photosest

I figured it out - here's the code that I used. This allows you to pull the information about an individual's albums(aka 'photosets') and then for the photos in each photoset.

Controller require 'flickraw'

class PhotosController < ApplicationController
  def index
    FlickRaw.api_key = ENV['FlickRaw_api_key']
    FlickRaw.shared_secret = ENV['FlickRaw_shared_secret']

    @photosets = flickr.photosets.getList(user_id: '67921947@N02').map do |set|
      flickr.photosets.getPhotos(photoset_id: set['id']).photo.map do |photo|
        FlickRaw.url_b(photo)
      end
    end
  end
end

View

<% @photosets[0].each do |image| %>
<%= image_tag image %>
<% end %>
