db:fixtures:dump

Adds db:fixtures:dump rake task to dump all ActiveRecord tables into yaml fixtures

May not work for tables with serialized columns.

Installation

Add this line to your application's Gemfile (likely the only group you'd want this in would be development):

gem 'db_fixtures_dump'

And then execute:

$ bundle

Or install it yourself as:

$ gem install db_fixtures_dump

Usage

$ rake db:fixtures:dump

Output directory

Just like for the db:fixtures:load , you may specify FIXTURES_PATH to be used as the output directory.

$ FIXTURES_PATH=db/backup rake db:fixtures:dump

Excluding models

You can exclude models by specifying a list as EXCLUDE_MODELS.

$ EXCLUDE_MODELS="MyLegacyModel AnotherOne" rake db:fixtures:dump

Or in combination with FIXTURES_PATH,

$ EXCLUDE_MODELS="MyLegacyModel AnotherOne" FIXTURES_PATH=test/fixtures rake db:fixtures:dump
