为列上的
字符串
类型插入的
二进制数据是什么意思…

在SQLite表中记录远程ip地址时，调试控制台中有一条消息：


Started GET "/test?name=abcde" for 127.0.0.1 at 2012-10-16 18:02:01 +0800
Processing by TestController#index as HTML
  Parameters: {"name"=>"abcde"}
   (0.1ms)  begin transaction
Binary data inserted for `string` type on column `query`
Binary data inserted for `string` type on column `remote_ip`
  SQL (0.6ms)  INSERT INTO "requests" ("controller", "query", "remote_ip") VALUES (?, ?, ?)  [["controller", "test"], ["query", "name=abcde"], ["remote_ip", "127.0.0.1"]]
   (2.5ms)  commit transaction


该表定义如下：


class CreateRequests < ActiveRecord::Migration
  def change
    create_table :requests do |t|
      t.string   :controller, :limit => 128
      t.string   :remote_ip,  :limit => 128
      t.string   :query,      :limit => 2048
    end
  end
end



这意味着您的Ruby字符串使用一些非默认编码进行标记：
