Adding prepareForValidation method

[robert-abram]

prepareForValidation change only data before validation and data are intact but prepareForPipeline change data. Is there any option to prepare date before validation, similar to prepareForValidation https://laravel.com/docs/9.x/validation#preparing-input-for-validation in FormRequest ?

Hi @abrampl 👍

as I understand it should work the same as prepareForValidation
just change the data and return it

   public static function prepareForPipeline(Collection $properties) : Collection
   {
       $properties->put('metadata', $properties->only(['release_year', 'producer']));
       
       return $properties;
   }

Nope it's not working the same @Nir-An , when you use prepareForPipeline, it will change you data, for example you create dto to check characters count, so before you check max size of string you want to strip_tags before you check size, if you do

 public static function prepareForPipeline(Collection $properties) : Collection
   {
       $properties->put('description', strip_tags($properties->only(['rdescription'])));
       
       return $properties;
   }

then of course before validation string is without tags, but after validation you want to save string with tags to db, and if you check description after dto is create and validated, it's show that value was overwriten, so in fact you loose orginal value of descrription
