Ruby on rails + Tinytds 未连接到 sql express

Question

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。

当我执行时

rake db:migrate

我明白了

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，我看到了

** 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“方法丢失”，但不知道这是问题所在还是其他问题。

Answer 1

更新了我的 environment.rb 文件以添加错误捕获

begin
  MySite::Application.initialize!
rescue Exception => ex
  puts '--------------------'
  puts ex.message
  puts '--------------------'
end

我可以看到 TinyTDS 出现错误

--------------------
Unable to connect: Adaptive Server is unavailable or does not exist
--------------------

所以现在我必须弄清楚这一点。
