Laravel 一件商品的条件在哪里？
Laravel where condition for one item?
我有 Products table 和 Categories table。
每个产品可能有一个或多个类别。为此我创建了 table: products_caetgories.
那么，如何设置 where 条件 product_category = 1？
我试过：
Product::with("categories")->where("product_category", 1)->get();
看看whereHas
you may use the whereHas and orWhereHas methods to put "where"
conditions on your has queries. These methods allow you to add
customized constraints to a relationship constraint, such as checking
the content of a comment:
Product::with("categories")->whereHas("categories", function($query){
$query->where('id','=',1);
})->get();
