laravel - 试图在 laravel-8 的 index.blade.php 的 listView 中显示为特定用户注册的某些产品
问题描述
我可以使用外键作为“user_id”为特定用户注册产品,用户有许多产品一对多的关系。 我想显示当我使用用户 2 登录时,它只会显示产品 5 和 7,而不是用户 1 注册的产品 6。但我的代码
public function index()
{
$products = Product::latest()->paginate(20);
return view('products.index',compact('products'))
->with('i', (request()->input('page', 1) - 1) * 5);
}
在 index.blede.php 中也显示产品 6 看到图像 你可以看到索引有另一个问题它显示 id 5 作为 id 1 和 id 6 作为 id 2 和 id 7 作为 id 3 如何修复它你能帮我吗?这是我完整的 ProductController.php

解决方案
您在没有设置条件的情况下获取产品,最新的方法是基于时间戳而不是 id。
您应该添加 where 子句,如Product::where('user_id', 2)
. 如果你想根据 id 获取,你可以使用latest('id')
.
