Database per branch so you can easily switch between database models.

Works with Rails 4.x and 5.x

bin/rails db:branch

Will create a new database and load it with seed. It will create .branchinator with db name for each env.

bin/rails db:unbranch

Will remove the database and .branchinator

bin/rails db:branch:reset

Shortcut for branch remove + create.

Put it into:

group :development, :test do
  gem 'branchinator'
end

In you database.yml put:

development:
  <<: *default
  database: <%= Branchinator.database %>
  
test:
  <<: *default
  database: <%= Branchinator.database %>

Update your .gitingore as well:

echo .branchinator >> .gitignore

By default database name is taken from application name and looks something like:

awesomeproject_branch_environment

If you want you can change the first part and the separator.

In your database.yml put:

branchinator:
  prefix: awesome-project
  separator: _
