Thor::Group:Class 的未定義方法“find_each”

Question

我編寫了一個 Thor 任務，該任務應該遍歷所有利用find_each用戶。 但我收到此錯誤消息：未定義方法find_each for Thor::Group:Class`

為什么 find_each 在這里不可用？ 運行User.find_each { |u| puts u.name } User.find_each { |u| puts u.name }放在 rails 控制台工作中。

class CloudImages < Thor
  require "./config/environment.rb"

  desc "save_user_avatar_urls", "Save existing AWS user avatars"
  def save_user_avatar_urls
    User.find_each do |user|
      next if user.avatar_url.blank?

      path      = URI(user.avatar_url).path
      image_url = $DOMAIN + path

      user.update_attribute(:aws_avatar_url, image_url)
    end
  end

end

Answer 1

更改User對::User

class CloudImages < Thor
  require "./config/environment.rb"

  desc "save_user_avatar_urls", "Save existing AWS user avatars"
  def save_user_avatar_urls
    ::User.find_each do |user|
      next if user.avatar_url.blank?

      # ...
    end
  end
end
