This method works great! I was very close to getting coercion to work,
but somehow my substitution returned '2' every time. Thanks all for the
help

Something along the lines of the following should work:
package Types;
use Moose::Util::TypeConstraints;
# note, need a type here, as otherwise coersions won't work if done as
a subtype of 'Str'
type "Types.pcr"
=> where { defined $_ and $_ =~ /^\d+$/ };
coerce "Types.pcr"
=> from "Str"
=> via { my $v = shift; $v =~ s/-//g; $v };
package UsageDetail;
use Moose;
# Note the 'coerce' flag and isa here
has pcr => (
is => "rw",
isa => "Types.pcr",
coerce => 1
);
package main;
my $dashful = UsageDetail->new( pcr => "9-8-7-6-5-4-3-2-1" );
my $dashless = UsageDetail->new( pcr => "123456789" );
print "Dashful: " . $dashful->pcr . "\n";
print "Dashless: " .$dashless->pcr . "\n"
-
The above gives:
Dashful: 987654321
Dashless: 123456789

I have been attempting to solve the following problem:
I have a class, 'UsageDetail' which takes a CSV phone call record and
inserts it into my database. One of the attributes, 'WirelessNumber' has
dashes in it, ie: '989-555-1212'. I don't want to store the dashes in the
db. I've rtfm over and over, but I haven't been successful in storing
without the dashes. I've tried subtypes, but that didn't work. BTW, the
values passed in to my constructor are not ONLY the 3-3-4 digit format,
sometimes the wireless number is 2 digits, and my WirelessNumber attr. isa
'Str' currently. Also, I can't modify the value passed into my constructor,
as it is used for many different tables. Any suggestions are greatly
appreciated.
