Method: Sequel::Plugins::ValidationClassMethods::ClassMethods#validates_schema_type

Defined in:
lib/sequel/plugins/validation_class_methods.rb

#validates_schema_type(*atts) ⇒ Object

Validates whether an attribute has the correct ruby type for the associated database type. This is generally useful in conjunction with raise_on_typecast_failure = false, to handle typecasting errors at validation time instead of at setter time.

Possible Options:

:message

The message to use (default: ‘is not a valid (integer|datetime|etc.)’)
