Answer 1

Your product model should look like this:
class Product extends Model
{
public $guarded = [];
public function category(){
return $this->belongsTo("App\Category", "category_id");
}
}
And this should be your Category model "Category.php":
class Category extends Model
{
public $guarded = [];
public function products(){
return $this->hasMany("App\Product", "category_id");
}
}
