update_in_batches

This gem adds a class/scope method to your ActiveRecord models, that gives you the same functionality of update_all but using the batching behavior of find_in_batches.

It is a short cut for:

Model.find_in_batches do |batch|
  ids = batch.map(&:id)
  Model.where(id: ids).update_all
end

Installation

Add this line to your application's Gemfile:

gem 'update_in_batches'

And then execute:

$ bundle

Or install it yourself as:

$ gem install update_in_batches

Usage

class Project < ActiveRecord::Base
end

Project.where(active: true).update_in_batches(active: false)
