PG Clone

This is a dead simple Postgres/Heroku cloning gem, to make it easier to pull database information from production to local.

Installation

Add this line to your application's Gemfile:

gem 'pgclone', git: "git://github.com/sashafklein/pgclone.git"

And then execute:

$ bundle

Usage

The gem is usable either from the command line or from your Rails app.

Command Line

Just call pgclone with the required arguments specified (or -h for more info). Those arguments are --appname (your Heroku appname), --owner (the local database owner), and --local-db (the local database name). PG Clone will take care of the rest:

$ pgclone -a my-heroku-app -o my-db-owner-username -l app_development

In Rails App

Set the mandatory configuration options in a config file:

# config/initializers/p_g_clone.rb
Pgclone.configure do |config|
    config.appname = 'my-heroku-app'
    config.owner = 'my-db-owner-username'
    config.local_db = 'app_development'
    config.file = 'temporary-dumpfile.dump' # optional
end

Then pull the data from your app like so:

Pgclone::Restore.new.go!

Or call directly with an options hash:

Pgclone::Restore.new({ appname: 'whatever' }).go!

Development

After checking out the repo, run bin/setup to install dependencies. Then, run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release to create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
