Validation rules: "lighter" required

[phlisg]

Hello,

Thank you for the package.

Testing around with it this morning, I found out that a field that has a required rule throws an error if not all translations have been set. How can I enforce a "lighter" requirement, such as: "required if 1 or more translations have been set"? Currently it's more: "all translations must be set".

Thank you for your help :-)

I need to think about it. I think this requires a very custom Laravel Validator rule.

I was using https://github.com/mrmonat/nova-translatable beforehand and it didn't have this issue, but I prefer this package with its language handling and field compatibility :-)

Hello @Tarpsvo

Just experimented this day with some simple rule, by using the resource's $request argument:

Text::make("Nom", 'name')
    ->translatable(Languages::all())
    ->rules('required_with', function($attribute, $value, $fail) {
       if (collect($this->request->get('name'))->values()->flatten()->filter()->count() === 0)
            return $fail("L'attribut {$attribute} ne peut être vide.");
        }),

This will check if any languages got filled or not, and will throw an error if it's definitely empty. Not the prettiest solution neither, but it works :D

Hi! I just released version 1.6.0 which has a new feature ->rulesFor() which should allow you to specify lighter rules.

Hello @Tarpsvo

Thank you for your follow up and sorry for my slow answer.

Following the documentation you wrote, I'm not sure I grasped how it works:

TextCounted::make('Name', 'name')
        ->help("Le nom de l'offre")
        ->translatable(Languages::all())
        ->required()
        ->rulesFor('fr', [
            'required',
        ])
       ->sortable()),

If I leave the name.fr blank and fill something else I get no errors

Thank you for your help :)

@phlisg I was facing the same problem... But after surfing the source code I found the error.

Even you are setting the rule properly, the validation of that rules is done in the HandlesTranslatable trait. You could simply use the trait in your nova resource and it should work like a charm 😉

I still can't find a way to mark a field as "at least one language is required".

->rules('required') requires filling in all the fields. ->rulesFor('en', ['required']) requires filling in a specific language.

Is it possible to require filling in at least one/any language?
