我正在尝试让 Rails 应用程序连接到 SQL Express 实例。我在windows环境下工作。
我不想设置 DSN，所以我选择了 Tindy TDS。不幸的是，我无法让它工作。
当我执行
rake db:migrate
我懂了
rake db:migrate
rake aborted!
closed connection
C:/site/config/environment.rb:5:in `<top (required)>'
Tasks: TOP => db:migrate => environment
(See full trace by running task with --trace)
当我运行跟踪时，我看到
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
rake aborted!
closed connection

Tasks: TOP => db:migrate => environment
我的 database.yml 是
development:
adapter: sqlserver
database: MyDatabase
dataserver: localhost\SQLEXPRESS
mode: dblib
username: sa
password: "1234"
在跟踪文件中，我看到“缺少方法”，但不知道这是问题所在还是其他原因。
