Laravel 对关系表的雄辩查询 [英] Laravel eloquent query on a relational table

问题描述

我对 laravel eloquent 还很陌生，我正在尝试编写一个嵌套查询来获取食物和餐厅食物的数据

i am fairly new to laravel eloquent and i am trying to write a nested query to get data of food and food of resturent

我有两张表，一张是'food_list'，主要包含'title','type'类型是 int 0/1，0 表示素食，1 表示非素食另一张桌子我有 resturent _food其中有 restaurant_id, food_id,price, image

I have two table one is 'food_list' which mainly contain 'title','type' Type is int 0/1, 0 means veg and 1 means non veg Another table i have resturent _food Which has restaurant_id, food_id,price, image

现在我想得到只有蔬菜的 tge 餐厅的食物清单

Now i want to get food list of tge resturent which is only veg

所以我写了一个这样的查询

So i wrote a query like this

RestaurantFood:with(['foodDetail'=>function($q){
$q->where('type',0);}])->where('id',$id)->get();

但这给出了错误的答案

谁能帮帮我

推荐答案

使用 whereHas():

RestaurantFood::with('foodDetail')->whereHas('foodDetail',function($q){
         $q->where('type',0);
})->where('id',$id)->get();
