instance method `update!`

Ruby on Rails 7.1.6

Since v7.0.10

Available in: v7.0.10 v7.1.6 v7.2.3 v8.0.4 v8.1.2

Compare with:

update!(id = :all, attributes)

Updates the object (or multiple objects) just like #update but calls #update! instead of update, so an exception is raised if the record is invalid and saving will fail.

Parameters

id opt = :all
attributes req
