Duple makes it easy to move PostgreSQL data around between your deployment environments. Duple knows how to move data from one heroku environment to another and how to load it into your local database. It can execute rake or Heroku commands before and after your loading data into your target environment. This is great for scrubbing, replacing, trimming or generating data for your test environments.
Install the gem:
$ gem install duple
Generate a config file:
$ duple init
The generated config file contains samples of all the different ways you can figure the application. Read and modify it, or clear it out and write your own.
