💖 NAME 💖

Catmandu::Fix::validate — bestie, this one validates your data and keeps the receipts (aka the errors) 🔥

---

✨ SYNOPSIS ✨

# Check author field against a JSON Schema
validate('author', JSONSchema, schema: 'my/schema.json')
if exists(errors)
   ... # do something
end

# Check item against a custom validator, store in errors in 'warnings'
validate('author', MyValidatorClass, error_field: warnings)

Okay so literally just look at that second one — you can yeet your error messages into a field of your choosing, no biggie, we love a customizable queen 👑

---

🦋 DESCRIPTION 🦋

So here's the vibe: this Catmandu::Fix runs your data through a Catmandu::Validator and then — and this is the important part, bestie — it stores the errors in a field called errors so you can go back and inspect them later. No cap. It doesn't just silently fail on you, it tells you what went wrong and leaves a lil note 💅

---

🎀 CONFIGURATION 🎀

• error_field — the path where you wanna stash those errors. Defaults to errors, so if you don't say anything, that's where they're gonna live, periodt.

Also: any extra options you throw at this thing get passed straight through to the validator, so go wild 🫶
