下面列出了我的连接文件，我不确定自己做错了什么。

答案 0 :(得分：1)
ActiveRecord连接需要连接适配器来适当地转换SQL以适合与AR交互的数据库。 ActiveRecord附带了一组本地适配器，包括“ mysql2”，“ postgres”和“ sqlite3”，但是在这种情况下，您正在使用MSSQL（如连接配置中的adapter: 'sqlserver'所示），它将需要外部适配器。
在这种情况下，外部适配器是activerecord-sqlserver-adapter gem。
可以使用gem install activerecord-sqlserver-adapter来安装它，然后只需像处理其他gem一样在文件中要求它即可。
尽管该gem没有明确的依赖性（ActiveRecord之外），您将需要指定一种连接模式（或使用默认的：dblib）。到目前为止，使用默认设置是最简单的方法（而且我从未遇到过任何问题），但是此模式确实需要包含tiny_tds gem（您已经需要）

可能您必须按照我们的朋友所说的来安装activerecord-sqlserver-adapter。默认情况下，sqlite附带有ruby on rails。尝试安装rubymine IDE，它将帮助您使用界面配置数据库。看下面：
