Unique validation dynamic ignore

[horo42]

When having a unique constraint on a user data objects email field, how would you ignore the currently edited user models email?

Hi @horo42,

Good point! I've added support to the Unique rule to support closures so you can read the request:

laravel-data/docs/advanced-usage/validation-attributes.md

Line 855 in 912c51b

public string $value;

Looks cool, but in what world is that valid syntax?

[rubenvanassche]

Hmm, it is actually not allowed to use closures within attributes, my bad! In that case, I would add the rule to the static rules method, it seems that we cannot support this at this moment.

Yeah that's how I ended up doing it too. Hopefully they'll add support for closures in attributes in a future PHP version.

I tried this like

#[Unique('table_name', ignore: request()->get('column_name'))]

But the constructor gives an error Constant expression contains invalid operations.

What should i do?

Use the static rules method
