Regex validation error

Getting this error when validating:

validate match(:code, "^[A-Za-z0-9]+$/")

validate match(:code, "^[A-Za-z0-9]+$/")

**Error**
protocol String.Chars not implemented for type Regex (a struct)

Got value:

    ~r/^[A-Za-z0-9]+$/

**Error**
protocol String.Chars not implemented for type Regex (a struct)

Got value:

    ~r/^[A-Za-z0-9]+$/

Any idea what's wrong?

Huh...that's weird Can you set up a reproduction? That should work fine

Joan GavelánOP•2mo ago

Yes. I'll do it tomorrow as soon as possible

ken-kost•2mo ago

what if you put ~r? 🤔

Joan GavelánOP•2mo ago

Same thing. That's actually what I tried initially, then read the docs and changed it to the string version, but the problem persisted

ZachDaniel•2mo ago

Can you share the whole error including stack trace? (In general always do that)

ZachDaniel•2mo ago

Okay that's likely a bug in ash_phoenix

Joan GavelánOP•2mo ago

ZachDaniel•2mo ago

Yeah Make sure you're on the latest version also If that doesn't work please open an issue

Joan GavelánOP•2mo ago

Alright I think this has to do with how AshPhoenix is formatting the errors for Inertia right? Yes I'm on the latest version

ZachDaniel•2mo ago

Kk, then yeah we'll want to look at how that protocol is implemented and likely check for regex values in vars for example
