Custom Validation with relation

->rules([function ($record) {
    return function (string $attribute, $value, Closure $fail) use ($record) {
      if (Model::where('agreement_id', $replaceWithRelationID)->whereDate('start_date', '>=', $value)->exists()) {
        $fail("There is already a price agreement right/after this date");
      }
    };
}]),

->rules([function ($record) {
    return function (string $attribute, $value, Closure $fail) use ($record) {
      if (Model::where('agreement_id', $replaceWithRelationID)->whereDate('start_date', '>=', $value)->exists()) {
        $fail("There is already a price agreement right/after this date");
      }
    };
}]),

I need to replace replaceWithRelationID with the parameter ID from the url or the relationship its on.

if your slug is like mypage/{relationID} and you have a public $relationIDin your Page, you could access it like $this->relationID.

or you use it in a querystring -> info on that can be found here: https://laravel-livewire.com/docs/2.x/rendering-components

Oh - okay. So just to get you right: url looks like this /admin/company-agreements/{WHATEVER}/edit and you wanna access the "WHATEVER"?

BlackShadowOP•2y ago

yea basically, unless there is another way Maybe you can access the relation where the price will be saved on or something

Husky110•2y ago

Have you tried it via self::getRecord()?
