method

update!

v4.2.9 - Show latest stable - Class: ActiveRecord::Persistence

update!(attributes)

public

Updates its receiver just like update but calls save! instead of save, so an exception is raised if the record is invalid.

# File activerecord/lib/active_record/persistence.rb, line 260
    def update!(attributes)
      # The following transaction covers any possible database side-effects of the
      # attributes assignment. For example, setting the IDs of a child collection.
      with_transaction_returning_status do
        assign_attributes(attributes)
        save!
      end
    end

update!
