This package provides use different morphMap for different relationships.

If your polymorphic relation structures does not satisfy with each other, this package lets you use custom map for each relation definition.

Installation

composer require moneo/laravel-morphmap

Usage

class Post extends Model
{
    // 🚀 Add HasCustomMorphMap trait!
    use HasCustomMorphMap;

    public function __construct(array $attributes = [])
    {
        // 👋 Custom definition for Category relation!    
        $this->customMorphMap = [
            Category::class => 'post',
        ];
        
        // 👋 Default for all others! (__CLASS__ definition is default. You don't need to add this.)
        $this->defaultMorphType = Post::class;

        parent::__construct($attributes);
    }

    public function tags(): MorphToMany
    {
        return $this->morphToMany(Tag::class, 'taggable');
    }

    public function categories(): MorphToMany
    {
        return $this->morphToMany(Category::class, 'categoryable');
