参数未传递给 Rake 任务

Question

我有一个接受参数 :scope （如下）的 rake 任务。 我这样称呼 rake 任务：

rake podcast:generate_inventory["new"]

该任务过去完美地传递 :scope arg，但是，我今天注意到 arg 不再被传递。有谁知道为什么会发生这种情况？

namespace :podcast do

  task :itunes_top_300, [:scope] => :environment do |t,args|
    Podcast.podcast_logger.info("BEGIN: #{Time.now}")
    if args[:scope] == "new"
      Podcast.podcast_logger.info("NEW PODCASTS ONLY")
    end
    Podcast.itunes_top_rss
  end

  task :itunes_genres_top_300 => :itunes_top_300 do
    Podcast.itunes_genre_rss
  end

  task :site_and_feed_discovery, [:scope] => :itunes_genres_top_300 do |t,args|
    if args[:scope] == "new"
      Podcast.site_and_feed_discovery(:new_podcasts_only => true)
    else
      Podcast.site_and_feed_discovery
    end
  end

  task :social_discovery, [:scope] => :site_and_feed_discovery do |t,args|
    if args[:scope] == "new"
      Podcast.social_discovery(:new_podcasts_only => true)
    else
      Podcast.social_discovery
    end
  end

  task :fetch_episodes => :social_discovery do |t,args|
    Episode.episode_logger.info("BEGIN: #{Time.now}")
    Podcast.fetch_episodes
    Episode.episode_logger.info("END: #{Time.now}")
  end

  task :generate_inventory => :fetch_episodes do |t,args|
    Podcast.podcast_logger.info("Successful Rake")
    Podcast.podcast_logger.info("END #{Time.now}")
    Rake::Task['maintenance:daily'].invoke
  end
end

看起来您在 task :generate_inventory 定义中缺少 [:scope] 位。我怀疑将其添加回来会解决所有问题。

希望有帮助！
