如何在过滤元素时使sql查询显示每一行？

Question

我正在使用sequelize作为ORM通过“ category_id”过滤我的建立表。我的[[问题是我被category_id = 11过滤时，巫婆产生了类似：：>查询查询：

WHERE `subcategories`.`category_id` = 11;

给定JSON（仅包含一个子类别行）

"establishments": [
        {
            "id": 11,
            "name": "Tasco do Ti efe",
            "subcategories": [
                {
                    "category_id": 11,
                    "category_type": "fashion",
                    "SubCategoryEstablishements": {
                        "sub_category_id": 31,
                        "establishment_id": 11,
                        "createdAt": "2020-04-26 13:39:20",
                        "updatedAt": "2020-04-26 13:39:20"
                    }
                }
            ],
]

我希望能够找到合适的餐厅，并像这样拥有所有属于他的子类别：

"establishments": [
        {
            "id": 1,
            "name": "Melhor efef",
            "subcategories": [
                {
                "category_id": 21,
                "category_type": "beautycara",
                "SubCategoryEstablishements": {
                    "sub_category_id": 41,
                    "establishment_id": 11,
                    "createdAt": "2020-04-26 13:39:20",
                    "updatedAt": "2020-04-26 13:39:20"
                }
            },
            {
                "category_id": 11,
                "category_type": "fashion",
                "SubCategoryEstablishements": {
                    "sub_category_id": 31,
                    "establishment_id": 11,
                    "createdAt": "2020-04-26 13:39:20",
                    "updatedAt": "2020-04-26 13:39:20"
                }
            },
            {
                "category_id": 31,
                "category_type": "homefamily",
                "SubCategoryEstablishements": {
                    "sub_category_id": 51,
                    "establishment_id": 11,
                    "createdAt": "2020-04-26 13:39:20",
                    "updatedAt": "2020-04-26 13:39:20"
                }
            }
            ],

为了使这种情况发生，我应该对查询进行哪些更改？ 

我正在使用sequelize作为ORM通过“ category_id”过滤我的Establishment表。我的问题是我按category_id = 11进行了筛选，生成的内容类似于：查询作出：WHERE`...

您需要定义表establishment和subcategory的两个不同关联。一个关联将用于过滤，而另一个关联将用于连接establishment和subcategory。
