使用雄辩的关系统计产品和品牌评论

Question

I have three models:

class Brand extends \Eloquent {
protected $fillable = [];

public function product()
{
    return $this->hasMany('Product');
}
}



class Product extends \Eloquent {

protected $fillable = [];

public function reviews()
{
    return $this->hasMany('Review');
}   

public function brand()
{
    return $this->belongsTo('Brand');
}

}

class Review extends \Eloquent {
protected $fillable = [];

public function product()
{
    return $this->belongsTo('Product');
}   

}

I'm trying to display brand names along with product and review counts in a view:

{{ $brand->product->count() }} 

it works for this, but doesn't display reviews count:

{{ $brand->product->reviews->count() }}

neither for:

{{ $brand->product->reviews->count() }}

Errors I'm getting are:

ErrorException (E_UNKNOWN) 
Undefined property: Illuminate\Database\Eloquent\Collection::$review

ErrorException (E_UNKNOWN) 
Undefined property: Illuminate\Database\Eloquent\Collection::$reviews

Answer 1

I am using {{ count($brand->product) }} {{ count($brand->product->reviews) }}
