Valida...pendsOn(3pm)

💖 NAME 💖

Validation::Class::Directive::DependsOn — bestie, it's the DependsOn directive for Validation Class Field Definitions. That's the whole vibe. It's the little field-level rule that goes "hey, this thing can't show up alone, it needs its friends here first." 👑

You'll see it filed under the manual page name Valida...pendsOn(3pm) (yes the name is squished, that's just how the page is titled, don't @ me).

✨ VERSION ✨

version 7.900059

That's the one, that's the version, no cap. 💅

🦋 SYNOPSIS 🦋

okay so here's how you actually use it:

use Validation::Class::Simple;

my $rules = Validation::Class::Simple->new(
    fields => {
        password_confirmation  => {
            depends_on => 'password'
        }
    }
);

# set parameters to be validated
$rules->params->add($parameters);

# validate
unless ($rules->validate) {
    # handle the failures
}

see how password_confirmation is like "I'm not validating unless password is here too"? that's the entire plot. it's giving codependent in the healthiest way possible 🫶

🌸 DESCRIPTION 🌸

Validation::Class::Directive::DependsOn is a core validation class field directive, and what it does is validate the existence of dependent parameters. literally its whole job. it checks that the parameters it's depending on are actually there. that's it, that's the directive, and it ate. 🔥

• alternative argument: an-array-of-parameter-names

This directive can be passed a single value or an array of values:

fields => {
    password2_confirmation => {
        depends_on => ['password', 'password2']
    }
}

so one dependency? cute. a whole list of dependencies? also completely valid, you just hand it an array. main character energy either way ✨
