Laravel 获取一组关系项

Laravel get a collection of relationship items(Laravel 获取一组关系项)

问题描述

我被困在这个看似简单的任务上.

I'm stuck on this what seems like a simple task.

我有一个用户有很多商店，有很多产品..

我正在尝试获取某个用户的所有产品.

I'm trying to get all the Products for a certain User.

这是有效的，并且正在返回商店及其产品

This is working, and is returning the Shops with their Products

Auth::user()->shops()->with('products')->get();

但我只需要产品的集合.我尝试了以下但它搞乱了查询

But I need a Collection of only the Products. I tried the following but it's messing up the Query

Auth::user()->shops()->with('products')->select('products.*')->get();

知道我做错了什么吗?谢谢！

Any idea what I'm doing wrong? Thank you!

推荐答案

你可以使用这个:

Auth::user()->shops()->with('products')->get()->pluck('products')->flatten();

如果你不想复制，你可以使用->unique()

if you don't want replicate, you can use ->unique()

如果您想直接处理查询(用于表演):

If you want to directly work on a query (for performances):

 Product::whereHas('shops', function($query){
    $query->where('user_id', auth()->user()->id);
 })->get();
