Question

我正在从flickr中检索个人照片（专辑）的列表。如何从这个哈希数组中提取id，然后使用flickr.photosets.getPhotos列出每个相册中的图像？我还在学习Ruby，感觉非常困惑。我很感激任何朝着正确方向的努力。

当我尝试将set.each do .. anything添加到@photosets块时 - 我为'each'得到了一个no方法错误。

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 %>

当前输出

列出photosest

{  
  "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"
},
{  
   "id"   =>"72157633308505122",
   "primary"   =>"8674031898",
   "secret"   =>"8cd5722def",
   "server"   =>"8543",
   "farm"   =>9,
   "photos"   =>"22",
   "videos"   =>0,
   "title"   =>"Photo Midterm",
   "description"   =>"",
   "needs_interstitial"   =>0,
   "visibility_can_see_set"   =>1,
   "count_views"   =>"2",
   "count_comments"   =>"0",

   "date_create"   =>"1366676884",
   "date_update"   =>"1366943480"
}

Answer 1

你几乎就在那里。如果您打算在index.html.erb上输出照片集及其相应照片的数据，您可以尝试以下内容：

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

这将输出如下内容：

{  
  "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sets.each do .. anything无法理解您的意思，因为我在您的代码中看不到sets。

我想出来了 - 这是我用过的代码。这样您就可以获取有关个人相册（也称为“照片”的信息）的信息，然后提取每张照片集中的照片。

<强>控制器要求＆＃39; flickraw＆＃39;

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
