JRuby, Postgres & Rails
by tokumine
Just a quickie. When using Rails, Postgres and JRuby for the first time, you’ll need to install a jdbc-friendly database driver. The nice fast ones you’re used to written in C (like ruby-pg), will simply not work.
There seems to be lots of choice here, and dead ends of old attempts. The latest and greatest however is the activerecord-jdbc-adapter and it’s set of prepackaged-adaptors.
So, to use postgres, and are using the fabulous Ruby Version Manager, you would install the postgres adaptor gem like this:
gem install activerecord-jdbcpostgresql-adapter
Then your configure your database.yml
development: adapter: jdbcpostgresql username: blog password: hostname: localhost database: weblog_development
Job done!
