ruby-on-rails - 尝试进行简单搜索时使用YouTube_IT时出现问题-Rails 3.1

Question

我正在使用这个 gem :https://github.com/kylejginavan/youtube_it

我的VideosController看起来像这样:

class VideosController < ApplicationController
  def index
  client = YouTubeIt::Client.new(:username => YouTubeITConfig.username , :password => YouTubeITConfig.password , :dev_key => YouTubeITConfig.dev_key)
@video = client.videos_by(:user => 'marcamillion1983')

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

我的看法:

<%= @video %>

输出是这样的:

#<YouTubeIt::Response::VideoSearch:0x0000012995f7c0>

当我尝试执行@video.each do |video|时，它给我一个未知方法each的错误。

但是，当我在Ruby提示符下尝试该查询时，它返回结果:

ruby-1.9.2-p0 > client.videos_by(:user => 'marcamillion1983')

如何获得正确的输出，以便可以在 View 上显示视频？

谢谢。

Answer 1

尽管我自己没有使用过该特定的gem，但看起来视频本身存储在返回的videos对象的YouTubeIt::Response::VideoSearch属性中。尝试使用@video.videos.each do |video|，看看是否可行。
