Ruby Question

Selecting and updating multiple rows using Ruby ActiveRecord

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?

Answer

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