Dumpcar

Rake tasks for dumping and restoring the contents of the PostgreSQL database for your Rails application.

• Dump (rails dumpcar:dump) and restore your last dump (rails dumpcar:restore) with a single command
• Uses your Rails database credentials for your environment

Install the gem executing:

bundle add dumpcar
rails g dumpcar # creates db/dumps folder, adds it to .gitignore and commits

rails dumpcar:dump # creates a postgresql dump based on current time like db/dumps/20250601022124.dump
rails dumpcar:restore # restores the last dump made chronologically from the db/dumps directory

Outside of the rails dumpcar:dump and rails dumpcar:restore commands, don't expect any compatibility guarantees for now.

• Support other Rails database (MySQL and SQLite)
• Support other Rails environments than the current one
• Ability to clean your db/dumps directory of all dumps before a given time
• Add support for naming a dump (you can manually do this now but not via the rake task)
• Restoring a specific dump via filepath
• Restoring a specific dump by timestamp
• Restoring a specific dump by name
• Restoring a specific dump made before or after a given time
• Extension points for other ways to get a database (Easily get a dump from Heroku's Postgres backups, for example)

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You should run bin/appraisal rspec to run all of the tests on all of the supported Rails versions. You can also run bin/console for an interactive prompt that will allow you to experiment.
