Perl Validation::Class messages - perl

Question

I've write a custom class inherited from Validation::Class to define all mixins I need
Then whenever i want to use these mixins in any class, I just inherited from the custom class.
Its works perfectly but I want to customize all error messages. Example:
message required => '%s is required';
So I don't have to write it in each validation field like this.
field username => {
required => 1,
messages{
required => '%s is required'
}
};
But it doesn't seems to work, it's still displaying original Validation::Class error message.
Can I override all messages I need in my costume class?
My custom class looks like this:
#Validation.pm
package Validation;
use Validation::Class;
use File::Spec ;
BEGIN {
my ($volume, $directory, $file) = File::Spec->splitpath(__FILE__);
push ( #INC,$directory );
}
our #ISA = qw(Validation::Class);
# hook
build sub {
my ($self, #args) = #_; # on instantiation
};
# I have tried to but the message in here , but it doesn't work
#message required => '%s is reuqired';
# data filter template
mixin filter => {
filters => [qw/trim strip/],
};
# data validation template
mixin basic => {
max_length => 255,
messages => {
max_length => 'Invalid %s',
}
};
This is the child class inherited from my Validation class
#Person.pm
package person;
# Inherit my custom class instead of Validation::Class
use Validation;
our #ISA = qw(Validation);
load role => 'Validation';
# I want to have this message in all inherited classes
# here is my problem .. this line will override required message with my custom message
# but I have many classes like this class
# is there anyway to delete this line and to write it in the parent class
# so every child can use this message without duplicating it in them
message required => '%s is reuqired';
# data validation rules
field username => {
mixin => 'filter',
mixin => 'basic',
required => 1
};

I found the solution for the messages
I have added a new mixin in the parent class (my custom Validation class) like this
mixin my_messages => {
messages => {
required => '%s is reuqired',
pattern => 'Ivalid character found in %s',
}
};
You can add as many messages as you can.
Then use the mixin inside all fields in any child class.
example
field username => {
default => '',
mixin => 'my_messages',
};
Note that my_messages mixin must be the last rule in the field.
