Ruby Flickr API和Photosets

Question

我从flickr检索个人的照片集（专辑）列表。我如何从这个散列数组中提取ID，然后使用flickr.photosets.getPhotos来列出每个相册中的图像？我仍然在学习Ruby，并且对此感到非常困惑。我很感激任何正确的方向。

当我尝试将set.each do .. anything添加到@photosets块 - 我得到一个没有方法错误'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 - 这是我使用的代码。这使您可以获取有关个人相册（又称'照片'）的信息，然后获取每张照片集中的照片。

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。如果您的目的是将的photosets的输出数据和各自的图片在你index.html.erb，你可以尝试这样的：

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

这将输出类似：

{ 
    "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... } 

我不确定你的意思通过sets.each do .. anything不起作用，因为我的代码中没有看到sets。
