Adds dynamic relationship to Eloquent ORM models

Installation

composer require i-rocky/eloquent-dynamic-relation

Usage

Add the trait Rocky\Eloquent\HasDynamicRelation to your model as following

use Rocky\Eloquent\HasDynamicRelation;

class MyModel extends Model {
  use HasDynamicRelation;
}

Now define a relationship somewhere

In Laravel you can add this in your AppServiceProvider's boot method

MyModel::addDynamicRelation('some_relation', function (MyModel $myModel) {
    return $myModel->hasMany(SomeRelatedModel::class);
});

Now you can use the relation some_relation as if it's defined in your MyModel class.
