Show in json a Relationship

Question

I am making a system that there is a register of products, these products the same can be part of only one group, or not.

I have this model for Products:

    class Products extends Model
    {
        protected $fillable = ['nome', 'codigo', 'preco'];

        protected $hidden = ['id'];

        public function Groups()
        {
            return $this->hasOne('App\pGroup', 'produto_id', 'id');
        }
    }

And this model where I store the products that have a group

class pGroup extends Model
{
    protected $fillable = ['group_id', 'produto_id'];

    public function Group()
    {
        return $this->belongsTo('App\ProductGroup');
    }
}

In this pGroup model I just saved the product id and group id as a Foreign key.

Now, let’s go to the product controller.

public function find($nome){
    $locate= Products::where('nome', 'like', "$nome%")->with('groups.group')->get();

    return response()->json($locate, 200);
}

As you can see, everything looks right. The problem is that in json it creates two object arrays, a "Groups" it pulls the data from the pGroup table, which is a table that contains only the referenced ids and in the other "Group" object it pulls the data I want, which is the name of that group.

How do I display only one object containing the group name the product is in, passing through the Foreign key.
