CakePHP 3：findById大于0

Question

我在另一个模型的view()函数中对相关模型进行分页。

public function view($id = null)
    {
        $category = $this->Categories->get($id, [
            'contain' => ['Subcategories']
        ]);

        // paginate products
        $products = $this->paginate($this->Categories->Products->findByCategoryId($category->id, ['conditions' => ['stock >' => 0, 'selling_price >' => 0]]), [
          'limit' => 21
        ]);

        $this->set('products', $products);
        $this->set('category', $category);
        $this->set('_serialize', ['category']);
    }

我想限制数据以查找stock和selling_price大于0的位置。

但这不起作用。如何在findById上申请条件？

Answer 1

试试这个：

$products = $this->paginate($this->Products->findByCategoryId($categoryId)->where(['stock >' => 0, 'selling_price >' => 0])->limit(21));

给出$ classId。
