Overview
Active Record Validations
Active Record includes the majority of its validations from ActiveModel::Validations all of which accept the :on
argument to define the context where the validations are active. Active Record will always supply either the context of :create
or :update
dependent on whether the model is a new_record?.
Defined Under Namespace
Modules: ClassMethods Classes: AbsenceValidator, AssociatedValidator, LengthValidator, NumericalityValidator, PresenceValidator, UniquenessValidator
Instance Method Summary collapse
-
#save(**options) ⇒ Object
The validation process on save can be skipped by passing
validate: false
. -
#save!(**options) ⇒ Object
Attempts to save the record just like ActiveRecord::Base#save but will raise an ActiveRecord::RecordInvalid exception instead of returning
false
if the record is not valid. -
#valid?(context = nil) ⇒ Boolean
(also: #validate)
Runs all the validations within the specified context.

Instance Method Details
#save(**options) ⇒ Object
The validation process on save can be skipped by passing validate: false
. The validation context can be changed by passing context: context
. The regular ActiveRecord::Base#save method is replaced with this when the validations module is mixed in, which it is by default.

#valid?(context = nil) ⇒ Boolean Also known as: validate
Runs all the validations within the specified context. Returns true
if no errors are found, false
otherwise.
Aliased as #validate.
If the argument is false
(default is nil
), the context is set to :create
if new_record? is true
, and to :update
if it is not.
Validations with no :on
option will run no matter the context. Validations with some :on
option will only run in the specified context.
