Answer 1

It is applicable for Laravel 9, If your Laravel version is lower than check the many-to-many-polymorphic-relations for documenton appropriate your version.

In Package Model

/**
     * Get all of the shops for the package.
     */
    public function shops()
    {
        return $this->belongsToMany(Shop::class, 'shop_packages');
    }

In Shop Model

/**
     * Get all of the packages for the package.
     */
    public function packages()
    {
        return $this->belongsToMany(Package::class, 'shop_packages');
    }

Answer 2

Your DB capture does not correspond to your relationships.

In Package model you should have something like :

public function packages(){
   return $this->belongsToMany(Shop::class,'shop_packages');
}

Otherwise in Shop model you should have :

public function shops(){
   return $this->hasMany(Package::class);
}

You have to use the appropriate relationship regarding to your needs.
