Ruby Flickr API和Photosets

Question

我從flickr檢索個人的照片集（專輯）列表。我如何從這個散列數組中提取ID，然後使用flickr.photosets.getPhotos來列出每個相冊中的圖像？我仍然在學習Ruby，並且對此感到非常困惑。我很感激任何正確的方向。

當我嘗試將set.each do .. anything添加到@photosets塊 - 我得到一個沒有方法錯誤'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 

照片/ index.html.erb

<h1>Listing photosets</h1> 

<%= @photosets %>

Answer 1

我想通了 - 這是我使用的代碼。這使您可以獲取有關個人相冊（又稱'照片'）的信息，然後獲取每張照片集中的照片。

控制器 需要 '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 

查看

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

Answer 2

你快到了。如果您的目的是將的photosets的輸出數據和各自的圖片在你index.html.erb，你可以嘗試這樣的：

@photosets = flickr.photosets.getList(user_id: '67921947@N02').each do |set| 
    set["photos"] = flickr.photosets.getPhotos(photoset_id: set["id"]) 
end 

這將輸出類似：

{ 
    "id" =>"72157633435549025", 
    "primary" =>"8720558709", 
    "secret" =>"d6f79d3d3c", 
    "server" =>"7395", 
    "farm" =>8, 
    "photos" =>"8", 
    "videos" =>0, 
    "title" =>"Poetry Project", 
    "description" =>"", 
    "needs_interstitial" =>0, 
    "visibility_can_see_set" =>1, 
    "count_views" =>"4", 
    "count_comments" =>"0", 
    "can_comment" =>0, 
    "date_create" =>"1368044794", 
    "date_update" =>"1368044886" 
    "photos" => [{"id" => "2484", 
       "secret"=>"123456", 
       "server"=>"1", 
       "title"=>"my photo", 
       "isprimary"=>"0"}, 
       {"id" => "2483", 
       "secret" => "123456", 
       "server" => "1", 
       "title" => "flickr rocks", 
       "isprimary" => "1"}] 
}, 
{ # etc... } 

我不確定你的意思通過sets.each do .. anything不起作用，因爲我的代碼中沒有看到sets。
