【问题描述】：
您能否指出任何好的资源来展示如何将 Sql Server 连接到 Rails 应用程序（Windows 7）？
到目前为止，我已经完成了以下工作：
rails new simple_cms –d sqlserver
gem install bundle
rails s
在最后一条命令之后，抛出此错误：
C:\Sites\s_cms>rails s

PS：如果我使用 sqlite 作为数据库系统，我能够成功启动网络服务器（没有错误）。这可能意味着我的 rails 安装没有问题。我猜我可能需要在 database.yml 中添加某些东西或在某处写入数据库用户和密码。但是为什么这不是 sqlite3 所必需的呢？ 我还找到了这个资源，但不确定是否仍然适用（它指的是 rails 2.0，而我使用的是 rails 4.1.1）http://rubyrailsandwindows.blogspot.de/2008/03/rails-2-and-sql-server-2008-on-windows_24.html - 以及我尝试过但不适用的一些东西。 提前致谢。
稍后编辑：在编辑 database.yml（来自 config 文件夹）后，我还尝试了 rails s 以包含：
development:
adapter: sqlserver
encoding: unicode
database: cms
pool: 5
username: guest1
password: pwd1234%^&^
test:
adapter: sqlserver
encoding: unicode
database: cms
pool: 5
username: guest1
password: pwd1234%^&^
production:
adapter: sqlserver
encoding: unicode
database: cms
pool: 5
username: guest1
password: pwd1234%^&^
（当然，我之前还创建了一个名为 cms 的数据库，并使用指定的密码添加了一个名为 guest1 的用户，然后通过模仿本地 Sql Server 本身的网络连接来确保凭据可以连接到数据库)
执行此新操作后，我收到与上述类似的错误：
C:\Sites\simple_cms>rails s
C:/Ruby193/lib/ruby/gems/1.9.1/gems/activesupport-.1.1/lib/active_support/core_ext/module/aliasing.rb:32:in `alias_method': undefined method `add_order!' for class `Class' (Name Error)
from C:/Ruby193/lib/ruby/gems/1.9.1/gems/activesupport-4.1.1/lib/active_support/core_ext/module/aliasing.rb:32:in `alias_method_chain'
