HasTagsThrough trait

[sfinktah]

HasTags trait for models that are only related to the tagged table.

e.g., sites model has tags...

tag_id	taggable_type	taggable_id
262	App\Models\Site	69

articles model belong to a site, ...

class Site extends Model
{
    use HasTags;
    // ...
}

class Article extends Model
{
    use HasTagsThrough;

    public static $taggedModel = Site::class;

    // unrelated helper functions to permit `->tags()` to be called
    public function site() {
        return $this->belongsTo(Site::class);
    }

    public function tags() {
        return $this->site()->tags();
    }
   // ...
}

Model articles can now (for example) be used in conjunction with a Nova filter...

class SiteTagFilter extends MultiselectFilter
{
    public function apply(NovaRequest $request, $query, $value)
    {
        return $query->withAllTagsOfAnyType($value);
    }

    public function options(NovaRequest $request)
    {
        return Tag::all()->pluck('name', 'name')->all();
    }
}

class Article extends Resource
{
    // ...
    public function filters(NovaRequest $request) {
        return [
            new SiteTagFilter,
        ];
    }
    // ...
}

I'm going to pass on this to keep the package small.
