Class::Workflow::TransUsernContributedoPerloDocuransition::Validate::Simple(3) NAME Class::Workflow::Transition::Validate::Simple - Easier validation code. SYNOPSIS package MyTransition; use Moose; with qw/Class::Workflow::Transition::Validate::Simple/; # ... $t->clear_validators; $t->add_validators( sub { ... } ); DESCRIPTION FIELDS ignore_validator_rv This is useful if your validators only throw exceptions. Defaults to false error_state This contains a state that will be moved to if a validation error occurs. In conjunction with Class::Workflow::State::AutoApply this can work like a catch block. The instance will have the "error" attribute set. no_die If this is set, "validation_error" will not die even if "error_state" is not set. The instance will have the "error" attribute set, and will be reaccepted into it's current state, with the error. METHODS validators This is an optional list of sub refs which will be called to validate input before applying "body". They should raise an exception or return a false value if the input is bad. They may put validation result information inside the Class::Workflow::Context or equivalent, if one is used. A more comprehensive solution is to override the "validate" method yourself and provide rich exception objects with validation error descriptors inside them. The validators are invoked as methods on the transition. IF "ignore_validator_rv" is true then only exceptions are considered input validations. add_validators @code_refs clear_validators Modify the list of validators. ROLES This role consumes the following roles: o Class::Workflow::Transition::Validate perl v5.32.1 Class::Workflow::Transition::Validate::Simple(3)
