Update multiple records simultaneously with ActiveRecord in Rails using one query?

Question

Let\'s suppose I have a table called \'user_products\' and a corresponding model called UserProduct in my Rails application. I also have a field called \'is_temporary\' in my ta

Answer 1

UserProduct.update_all({:is_temporary => false}, {:user_id => 12345})

Answer 2

UserProduct.update_all({:is_temporary => false}, {:user_id => 12345})

Although beware: this skips all validations and callbacks, since no instance of UserProduct will ever be instanciated.

Answer 3

This is an old post. I updated this in case someone checks it :) (Rails 4)

DEPRECATION: Relation#update_all with conditions is deprecated. Please use Item.where(color: 'red').update_all(...) rather than Item.update_all(..., color: 'red').

So the query will be

UserProduct.where(:user_id => 12345).update_all(:is_temporary => false)

Cheers
