Laravel Datatable ManyToMany relationship with multiple tables

Here is how i would do,

In Offer.php

 class Offer extends Model {
    public function offer_countries() {
        return $this->hasMany(OfferOfferCountries::class,'offer_id','id');
    }

    public function offer_categories() {
        return $this->hasMany(OfferOfferCategories::class,'offer_id','id');
    }

    public function offer_creatives() {
        return $this->hasMany(OfferCreative::class,'offer_id','id');
    }

    public function offer_tools() {
        return $this->hasMany(OfferTools::class,'offer_id','id');
    }

    public function offer_traffic() {
        return $this->hasMany(OfferTraffic::class,'offer_id','id');
    }

    public function platforms() {
        return $this->hasMany(Platform::class,'offer_id','id');
    }
  }

In OfferOfferCountries.php

class OfferOfferCountries extends Model {
   public function countryDetail(){
     return $this->belongsTo(OfferCountries::class,'offercountry_id','id');
   }
}

In OfferOfferCategory.php

class OfferOfferCategory extends Model {
   public function categoryDetail(){
     return $this->belongsTo(OfferCategory::class,'offercategory_id','id');
   }
}

Now in the controller

public function getMediaData() {
        $data = Offer::with('offer_countries.countryDetail','offer_categories.categoryDetail','offer_creatives','offer_tools','offer_traffic','platforms')->get();

echo '<pre>';
print_r($data);

}

This should give you an array of objects of everything. You can use pivot table but I like this way.
