[0.2] Allow extending of validation rules

[wychoong]

this is a proof of concept on customising validation rules in hub. Current only applied for Product's collection.

now you can define more rules in config

# in config/getcandy-hub/product.php
<?php

use GetCandy\Models\CollectionGroup;

return [
    # ... 

    'validation' => [
        'variant.sku' => 'required|unique|min:8',
        'collections.*.group_id' => [
            'required',
            'distinct',
        ],
        'collections' => ['required' => true, 'array', function ($attribute, $value, $fail) {
            $missing = [];

            $collections = collect($value)->pluck('id', 'group_id');

            $groups = CollectionGroup::whereIn('id', [1, 2])
                ->select(['id', 'name'])
                ->get()
                ->pluck('name', 'id');

            $missing = $groups->diffKeys($collections)->all();

            if (filled($missing)) $fail("Require Collection Group from: " . implode(', ', $missing));
        }],
    ]
];

result

issue
the main problem with the current implementation is unable pass in Model instance to those additional rules. it can be done but I don't think is good approach.

@glennjacobs need your input on this

this is referring to this https://discord.com/channels/497326121441034240/916819091841486869/1001891823146520646

@alecritson thoughts on this?

[alecritson]

@glennjacobs I'm not against this but don't feel like the config is the correct place. Due to some validation using closures (like in the example above) this means that Laravel wouldn't be able to serialise the config for optimisation.

Would it not be better to provide a method on the component that dev's can tap into at the component level? Something like:

ProductEdit::extendValidation([
    'name' => 'required|min:50',
]);

Fair point. Will look into this approach

[wychoong]

now can extend validation by using component method

ProductCreate::extendValidation(
            [
                'variant.sku' => ['required', 'min:8'],
                'collections' => ['required', 'array', function ($product) {
                    return function ($attribute, $value, $fail) use ($product) {
                        $missing = [];

                        $collections = collect($value)->pluck('id', 'group_id');

                        $groups = CollectionGroup::whereIn('id', [1, 2])
                            ->select(['id', 'name'])
                            ->get()
                            ->pluck('name', 'id');

                        $missing = $groups->diffKeys($collections)->all();

                        if (filled($missing)) $fail($product->translateAttribute('name') . " Require Collection Group from: " . implode(', ', $missing));
                    };
                }],
            ]
        );

$product is able to pass from component by using app()->call(...)

@wychoong It's looking promising, I can see it's still in draft, is there still work you want to do on it?

hey. I think in terms of implementation it is done. I kept it as draft is to get feedbacks and since this opens up a lot more validation, we also need to add few more changes to display the error message.
in

• getSideMenuProperty hasError
• @error in blade

[glennjacobs]

@wychoong should we have documentation for this?

Awesome. Just Alec's question and then I think this can be merged?

hrmmm... you referring to this?

not sure why its pending or should i click the resolve converstation?

[wychoong]

this idea is taken from Filament on allowing injecting value for closure

[wychoong]

figured it out that i need to submit my "review" comment 😓

[glennjacobs]

@wychoong the VuePress config file has conflicts now. You have changed the indentation from 2 spaces to 4 spaces, any reason for this?

I think that was because of my VSCode does that, can you help on this as I’m away from computer till the weekend

[wychoong]

@glennjacobs it's ready for review
