This method is a shortcut to all default validators and any custom validator classes ending in ‘Validator’. Note that Rails default validators can be overridden inside specific classes by creating custom validator classes in their place such as PresenceValidator .

The power of the validates method comes when using custom validators and default validators in one call for a given attribute.

Validator classes may also exist within the class being validated allowing custom modules of validators to be included as needed.

The validators hash can also handle regular expressions, ranges, arrays and strings in shortcut form.

When using shortcut form, ranges and arrays are passed to your validator’s initializer as options[:in] while other types including regular expressions and strings are passed as options[:with] .

:on - Specifies the contexts where this validation is active. Runs in all validation contexts by default (nil). You can pass a symbol or an array of symbols. (e.g. on. create or on. custom_validation_context or on: [:create. custom_validation_context] )

:if - Specifies a method, proc or string to call to determine if the validation should occur (e.g. if. allow_validation, or if: Proc.new < |user| user.signup_step > 2 > ). The method, proc or string should return or evaluate to a true or false value.

:unless - Specifies a method, proc or string to call to determine if the validation should not occur (e.g. unless. skip_validation, or unless: Proc.new < |user| user.signup_step <= 2 > ). The method, proc or string should return or evaluate to a true or false value.

:strict - If the :strict option is set to true will raise ActiveModel::StrictValidationFailed instead of adding the error. :strict option can also be set to any other exception.

Finally, the options :if, :unless, :on, :allow_blank, :allow_nil, :strict and :message can be given to one specific validator, as a hash:
