答案 0 :(得分：0)

你的SQL查询是错误的。正确的sql更新查询应该是这样的

update photos set photos.user_id = albums.user_id from albums where albums.id = photos.album_id

请将您的迁移文件更改为此

class AddUserIdToPhotos < ActiveRecord::Migration
  def self.up
    add_column :photos, :user_id, :integer
    execute "update photos set photos.user_id = albums.user_id from albums where albums.id = photos.album_id"
  end

  def self.down
    remove_column :photos, :user_id
  end
end

再次运行。
