TODO: why are there 3 entry points to this ivar? disable_auto_validations, disabled_auto_validations?, auto_validations_disabled?
Auto-generate validations for a given property. This will only occur if the option :auto_validation is either true or left undefined.
Triggers that generate validator creation :required => true Setting the option :required to true causes a validates_presence_of validator to be automatically created on the property :length => 20 Setting the option :length causes a validates_length_of validator to be automatically created on the property. If the value is a Integer the validation will set :maximum => value if the value is a Range the validation will set :within => value :format => :predefined / lambda / Proc Setting the :format option causes a validates_format_of validator to be automatically created on the property :set => ["foo", "bar", "baz"] Setting the :set option causes a validates_within validator to be automatically created on the property Integer type Using a Integer type causes a validates_numericality_of validator to be created for the property. integer_only is set to true BigDecimal or Float type Using a Integer type causes a validates_numericality_of validator to be created for the property. integer_only is set to false, and precision/scale match the property Messages :messages => {..} Setting :messages hash replaces standard error messages with custom ones. For instance: :messages => {:presence => "Field is required", :format => "Field has invalid format"} Hash keys are: :presence, :format, :length, :is_unique, :is_number, :is_primitive :message => "Some message" It is just shortcut if only one validation option is set
