我试图像这样从Realm对象中过滤出一个ID:
let itemsInCart = realm.objects("Cart").filtered("id = " + itemId);
我的购物车模式如下:
export const CART_SCHEMA = "Cart";
export const CartSchema = {
name: CART_SCHEMA,
primaryKey: "id",
properties: {
id: "string",
quantity: "int",
productName: "string",
productImage: "string"
}
};
我想检查ID是否存在于我的Cart对象中,但是每当我尝试过滤出ID时,都会出现以下错误:
答案 0 :(得分:1)
尝试在Realm中按ID过滤对象
let itemsInCart = realm.objects("Cart").filtered("id == $0", itemId);
