Selecting and updating multiple rows using Ruby ActiveRecord

Question

So I have an array of user uuids and I want to update one field that all of those users have(I am guaranteed that they have a value for that field).

I know that I should be using update_all to update all of the fields in one transaction. However, I'm not sure how to select users given an array of user uuids that can then be supplied to the update_all.

What can I do?

User.where(uuid: [uuid_array]) will return an ActiveRecord Relation, on which you can call update_all.
