Question

我下载了BitNami的Jruby。一切都很好，但是当我想连接到SQL Server 2008时，出了点问题。

database.yml如下

development:
       adapter: sqlserver
      host: 127.0.0.1
      instanceName: SQLServer2008
      database: truetemp
      username: sa
      password: 7354500

我使用命令“Jruby -S rails generate scaffold产品名称：string ....”，ROR效果很好; 但命令“rake db：migrate --trace”失败。

f：\ tmp \ RubyMine201207＆gt; rake db：migrate --trace   **调用db：migrate（first_time）   **调用环境（first_time）   **执行环境   **调用db：load_config（first_time）   **调用rails_env（first_time）   **执行rails_env   **执行db：load_config rake aborted！请安装sqlserver适配器：gem install activerecord-sqlserver-adapte r（没有这样的文件   加载 - active_record / connection_adapters / sqlserver_adapter）

Answer 1

确保将以下行添加到Gemfile

gem 'activerecord-sqlserver-adapter'

Rails通过activerecord-sqlserver-adapter连接到SQL Server 2008
