使用hasMany关系时如何从帖子表中获取用户 [英] How to get a user from post table when using hasMany relationship

问题描述

我对Laravel还是很陌生，现在已经困扰了我好一段时间了，在尝试使用hasMany关系通过帖子表获取用户名时，我遇到了一个问题.希望添加的代码有助于更好地理解问题.谢谢

I am pretty new to Laravel and i have been stuck with this problem for quite a while now ,I face a problem when trying to get a user name through post table using hasMany relationship. Hope the added code helps to understand the problem better. Thank you

   public function main_page(){

        $post= Post::all();


        return view('main' , compact('post') );
    }

@extends('layouts.app')


@section('content')

    @foreach ($post as $p)


    {{$p->users()->name }}

    @endforeach

@endsection

    public function users(){

        $this->belongsTo('App\User');
    }

我希望显示该帖子的作者姓名，但实际情况并非如此.我收到错误消息:

I expect that author's name of the post would be displayed ,but it is not the case. I get an error:

Trying to get property 'name' of non-object 

我的帖子表如下:

id
user_id
title
content
created_at
updated_at

推荐答案

您没有在您的 Post 模型中以关系返回用户，请尝试以下操作:

You're not returning the user in the relation in your Post model, try this:

public function user(){

   return $this->belongsTo('App\User');
}

函数的名称应为 user ，如@Ross Wilson所建议的单数形式.

The name of the function should be user, on singular as @Ross Wilson suggested.

您认为您可以这样做:

@section('content')
    @foreach ($post as $p)
    {{$p->user->name }}
    @endforeach
@endsection
