rails3 会话存储

Question

请问您能告诉我 - 如何在 rails3 应用程序外部 Active Record 会话存储中使用？

在 rails2 中很简单

ActiveRecord::SessionStore::Session.establish_connection("sessions_#{RAILS_ENV}")

但是关于 rails3 吗？

Answer 1

查看config/initializers/session_store.rb

注释掉关于使用:cookie_store的行

取消注释底部关于使用:active_record_store的行

# 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

注意：“MyApp”将是您的应用程序的名称。

Answer 2

查看activerecord-3.0.0.rc/lib/active_record/session_store.rb的来源我看到了：

165     # The database connection, table name, and session id and data columns
166     # are configurable class attributes.  Marshaling and unmarshaling
167     # are implemented as class methods that you may override.

183       # :singleton-method:
184       # Use the ActiveRecord::Base.connection by default.
185       cattr_accessor :connection

208         def connection
209           @@connection ||= ActiveRecord::Base.connection
210         end

所以，您应该可以执行以下操作：ActiveRecord::SessionStore::Session.connection = establish_connection("sessions_#{RAILS_ENV}")，但我还没有测试过。

您还可以创建自己的会话类，您可以从同一个文件中更好地控制它如何连接到数据库：

 34   # You may provide your own session class implementation, whether a
 35   # feature-packed Active Record or a bare-metal high-performance SQL
 36   # store, by setting
 37   #
 38   #   ActiveRecord::SessionStore.session_class = MySessionClass
 39   #
 40   # You must implement these methods:
 41   #
 42   #   self.find_by_session_id(session_id)
 43   #   initialize(hash_of_session_id_and_data)
 44   #   attr_reader :session_id
 45   #   attr_accessor :data
 46   #   save
 47   #   destroy

Answer 3

你必须使用它。

Rails.application.config.session_store :active_record_store

我不确定如何设置表名。
