在rake任务中运行.sql文件

Question

我正在尝试开始使用Ruby代码库并致力于添加新的Rake任务。我正在尝试在连接的mySQL数据库上运行.sql文件。

namespace :db do
  task :seed do
    connection = ActiveRecord::Base.connection
    puts connection
    sql = File.read('./docker/seed/warehouse-b2b/addresses.sql')
    statements = sql.split(/;$/)
    ActiveRecord::Base.transaction do
      statements.each do |statement|
        connection.execute(statement)
      end
    end
  end
end

这里是我如何调用任务rake db:seed --trace。这是我得到的错误堆栈跟踪信息

Mysql2::Error: Query was empty:

Ruby的新手，无法解决问题。任何帮助表示赞赏！

按照惯例，数据库播种必须在seeds.rb文件中完成
