ActiveRecord::Random

The most perfomant way to get random records from ActiveRecord. In fact, it's the only way to get random records from ActiveRecord. For now it supports only PostgreSQL.

Installation

Install the gem and add to the application's Gemfile by executing:

bundle add random-rails

If bundler is not being used to manage dependencies, install the gem by executing:

gem install random-rails

Usage

Just call random on your ActiveRecord model and enjoy:

User.random
# => [#<User id: 1, name: "John", ...>]

You can also pass precision to random method:

User.random(0.1)
# => [#<User id: 1, name: "Nikolas", ...>]

Combine with other ActiveRecord methods? No problem:

User.where(age: 18..30).random(0.1).limit(10)
# => [#<User id: 1, name: "Nikolas", ...>, #<User id: 2, name: "John", ...>, ...]

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also 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, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
