DBIx::...Columns(3pm)

💖 NAME 💖

DBIx::Class::Helper::ResultSet::NoColumns — look ma, no columns! 🫶

This page is from the User Contributed Perl Documentation collection, bestie, and it's giving very niche-but-iconic. 💅

---

✨ SYNOPSIS ✨

Okay so first you gotta set up your resultset class like this, copy it exactly, no freestyling:

package MySchema::ResultSet::Bar;

use strict;
use warnings;

use parent 'DBIx::Class::ResultSet';

__PACKAGE__->load_components('Helper::ResultSet::NoColumns');

Then, over in your code that's actually using the resultset, you do the thing:

# in code using resultset:
my $rs = $schema->resultset('Bar')->no_columns->search(undef, {
   '+columns' => { 'foo' => 'me.foo' },
});

See how it just... wipes the slate clean and then you add exactly what you want? That's the whole vibe. 🦋

🌸 DESCRIPTION 🌸

This component simply gives you a method to clear the set of columns to be selected. It's just handy sugar — like, no big dramatic lore, it's a lil convenience and that's on periodt. 🍓

Also, heads up: peep "NOTE" in DBIx::Class::Helper::ResultSet for a nice way to apply this to your entire schema. Whole-schema glow-up, we love to see it. 👑

🎀 METHODS 🎀

no_columns

Signature, verbatim, do not come for me:

$rs->no_columns

Returns resultset with zero columns configured, fresh for the addition of new columns. Literally a blank canvas, main character energy only. ✨
