Laravel 4雄辩的分页相关模型

Question

I'm working on Laravel project that has two models: Offer belongsTo Category . 我正在研究具有两个模型的Laravel项目： Offer BetweenTo Category 。

It's easy to paginate the results when I'm retrieving all records: 在检索所有记录时，很容易对结果进行分页：

$offers = Offer::paginate(10);

But when I'm trying to just retrieve Offers that has specific Category , It just do not work: 但是，当我试图只是检索Offers具有特定Category ，它只是不工作：

$category = Category::whereId($category_id)->with('offers')->first()->paginate(10);

and I get this error: 我得到这个错误：

 Undefined property: Illuminate\Pagination\Paginator::$offers

UPDATE: 更新：

I've solved it by replacing the second code with this: 我已经通过替换第二个代码来解决了这个问题：

$category = Category::find($category_id);
$offers = $category->offers()->paginate(10);

Answer 1

replace the second code with this: 将第二个代码替换为：

$category = Category::find($category_id);
$offers = $category->offers()->paginate(10);
