How do i split a variable of numbers with spaces... for example

DBIx::Class::DynamicDefault(3pm) User Contributed Perl Documentation DBIx::Class::DynamicDefault(3pm)
NAME
DBIx::Class::DynamicDefault - Automatically set and update fields
SYNOPSIS
package My::Schema::SomeTable;
__PACKAGE__->load_components(qw/DynamicDefault ... Core/);
__PACKAGE__->add_columns(
quux => { data_type => 'integer' },
quux_plus_one => { data_type => 'integer',
dynamic_default_on_create => &quux_plus_one_default,
dynamic_default_on_update => 'quux_plus_one_default', },
last_changed => { data_type => 'integer',
dynamic_default_on_create => 'now',
dynamic_default_on_update => 'now, },
);
sub quux_plus_one_default {
my ($self) = @_;
return $self->quux + 1;
}
sub now {
return DateTime->now->epoch;
}
Now, any update or create actions will set the specified columns to the value returned by the callback you specified as a method name or
code reference.
DESCRIPTION
Automatically set and update fields with values calculated at runtime.
OPTIONS
dynamic_default_on_create
dynamic_default_on_create => sub { ... }
dynamic_default_on_create => 'method_name'
When inserting a new row all columns with the "dynamic_default_on_create" option will be set to the return value of the specified callback
unless the columns value has been explicitly set. The callback, that'll be invoked with the row object as its only argument, may be a code
reference or a method name.
dynamic_default_on_update
dynamic_default_on_update => sub { ... }
dynamic_default_on_update => 'method_name'
When updating a row all columns with the "dynamic_default_on_update" option will be set to the return value of the specified callback
unless the columns value has been explicitly set.
Columns will only be altered if other dirty columns exist. See "always_update" on how to change this.
always_update
always_update => 1
When setting "always_update" to 1 "dynamic_default_on_update" callbacks will always be invoked, even if no other columns are dirty.
