Update ActiveRecord Instance With Validation Context

Published: Feb 6, 2018 by Midwire

Validation contexts are really useful, however only the methods valid? and save allow you to pass a custom validation context. What about update?

If you want to pass a validation context when calling update on an Active Record model instance, add this to your base class, which is ApplicationRecord by default in Rails versions starting with 4.x.

class ApplicationRecord < ActiveRecord::Base
  self.abstract_class = true

  def update_with_context(new_attributes, context)
    with_transaction_returning_status do
      assign_attributes(new_attributes)
      save(context: context)
    end
  end
end
