MenuItem link for lens

[hivokas]

It would be great to me able to pass lens class as a second param to MenuItem::resource() to add the menu link to resource lens.

Agree, but it's a little tricky since lenses can be used on multiple resources (they are similar to filters in this regard). They are not explicitly tied to an individual resource.

It would be nice if it was possible to create Resource-specific Lenses. Not sure where (if) one could make a feature request for that. 🙂
My use case for Lenses are pretty much always for specific Resources.
It's probably the wrong usage, but.. I create them to show 'reports' for specific data, or show data and Actions to specific tasks.
Technically speaking, it obviously wouldn't change much (nothing?), as they'd still be applied the same way, just throw an Exception (or so), when used on another Resource.

Yeah, that's why I think this method should accept both resource class name and lens class name: #4280 (comment)

FWIW - I've created a method in my NovaServiceProvider (since I only need it there), to easily create Resource-specific Lens links.

/**
 * @param  class-string<Lens>  $lens
 * @param  class-string<Resource>  $resource
 */
private static function resourceLensUrl(string $lens, string $resource): string
{
    return "/resources/{$resource::uriKey()}/lens/{$lens::make()->uriKey()}";
}

// ...
MenuItem::link(__('Link Title'), path: self::resourceLensUrl(
    MyLens::class,
    MyResource::class,
));

Figuring out a more permanent solution to call directly on a MenuItem would obviously be preferred. 🙂

Here is my solution:

<?php

namespace App\Nova\Support\Menu;

use Laravel\Nova\Lenses\Lens;

class MenuItem extends \Laravel\Nova\Menu\MenuItem
{
    public static function lens($resourceClass, $lensClass): self
    {
        /** @var Lens $lens */
        $lens = new $lensClass;

        return self::resource($resourceClass)
            ->path('/resources/'.$resourceClass::uriKey().'/lens/'.$lens->uriKey())
            ->name($lens->name());
    }
}
