Inside Rails

 

To use activerecord-jdbc-adapter with JRuby on Rails:

1. Choose the adapter you wish to gem install. The following pre-packaged adapters are available:

• base jdbc (activerecord-jdbc-adapter). Supports all available databases via JDBC, but requires you to download and manually install the database vendor's JDBC driver .jar file.
• mysql (activerecord-jdbcmysql-adapter)
• postgresql (activerecord-jdbcpostgresql-adapter)
• derby (activerecord-jdbcderby-adapter)
• hsqldb (activerecord-jdbchsqldb-adapter)
• h2 (activerecord-jdbch2-adapter)

2. Run the "jdbc" generator to prepare your Rails application for JDBC.

To perform batch operations in MacPorts you can use the predefined pseudo-portnames. RubyGems has no such thing, but instead it can handle regular expressions. So to uninstall all gems of your default RubyGems installation you can simply issue the following command.

sudo gem uninstall --a --ignore-dependencies .+
