ruby-on-rails – Rails 3：将活动记录中的会话保存(不是cookie)

我正在使用以下版本：

> rails 3.2.6,
> ruby?? 1.9.3p194(2012-04-20修订版35410)[x86_64-darwin11.4.0]

要开始在Active Record中使用会话存储而不是cookie,我做了以下：

>更新config / initializers / session_store.rb.
评论第一行,取消注释最后一行,所以我有：

# Be sure to restart your server when you modify this file.

# Myapp::Application.config.session_store :cookie_store,key: '_elegato_session'

# Use the database for sessions instead of the cookie-based default,# which shouldn't be used to store highly confidential information
# (create the session table with "rails generate session_migration")
Myapp::Application.config.session_store :active_record_store

> rake db：sessions：create

invoke  active_record
  create    db/migrate/20120729025112_add_sessions_table.rb

> rake db：migrate

==  CreateLinkedinUsers: migrating ============================================
-- create_table(:linkedin_users)
  -> 0.0236s
==  CreateLinkedinUsers: migrated (0.0237s) ===================================

==  AddSessionsTable: migrating ===============================================
-- create_table(:sessions)
  -> 0.0012s
-- add_index(:sessions,:session_id)
  -> 0.0006s
-- add_index(:sessions,:updated_at)
  -> 0.0006s
==  AddSessionsTable: migrated (0.0026s) ======================================

>要找出实际创建的表,我打开sqlite3文件

sqlite> .schema sessions
CREATE TABLE "sessions" ("id" INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,"session_id"   varchar(255) NOT NULL,"data" text,"created_at" datetime NOT NULL,"updated_at" datetime NOT NULL);
CREATE INDEX "index_sessions_on_session_id" ON "sessions" ("session_id");
CREATE INDEX "index_sessions_on_updated_at" ON "sessions" ("updated_at");

因此,会话表中有一个“数据”字段,用于存储与会话相关的所有内容.

现在,我的问题:-)

我需要在会话中存储2个变量的值：access_token和request_token.
可以使用以下吗？ (我用于存储cookie的会话值的方式)

session[:access_token] = <blah>
session[:request_token] = <some other blah?

如果它有效,那么ruby会将这两个变量存储在数据表的“data”字段中.

非常感谢您的帮助！
