NAME

Interchange6::Schema::Component::Validation

SYNOPSIS

  package My::Result;
  __PACKAGE__->load_components(qw(
    +Interchange6::Schema::Component::Validation
  ));
  sub validate {
    my $self = shift;
    my $schema = $self->result_source->schema;
    unless ( $self->some_column =~ /magic/ ) {
      $schema->throw_exception("some_column does not contain magic");
    }
  }

DESCRIPTION

This component allows validation of row attributes to be deferred until other components in the stack have been called. For example you might want to have the TimeStamp component called before validation so that datetime columns with set_on_create are defined before validation occurs. In this case your local_components call might look like;

__PACKAGE__->load_components(
qw(TimeStamp +Interchange6::Schema::Component::Validation) );

In order to fail validation the "validation" method must throw an exception.

METHODS

insert

Overload insert to call "validate" before insert is performed.

update
