UpdateValuesAll

The gem allows to update AR-records in batch

Installation

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

$ bundle add update_values_all

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

$ gem install update_values_all

Usage

Assume you have AR-model

class User < ActiveRecord::Base
  store :address, accessors: %i[city]
end

And some records

User.create!(id: 1, city: 'Moscow', name: 'Ivan')
User.create!(id: 2, city: 'Vladivostok', name: 'Petr')

The gem defines method User.update_values_all which allows to batch update attributes

changed_ids =
  User.update_values_all(
    [
      { id: 1, address: { city: 'Berlin' }, name: 'Hanz' },
      { id: 2, address: { city: 'London' }, name: 'John' }
    ],
    key_to_match: :id, # :key_to_match can be omitted if it matches primary key
 )

changed_ids # [1, 2]
User.find(1).name # Hanz
User.find(1).city # Berlin
User.find(2).name # John
User.find(2).city # London

Records are only updated if attributes changed (and also updated_at).

Sometimes you want to update updated_at regardless of whether the attributes have changed. In that case you may pass param touch: true.

changed_ids = User.update_values_all([{ id: 1, name: 'Hanz' }], key_to_match: :id, touch: true)

changed_ids = []
User.find(1).updated_at # changed
