我该如何吸引发布该帖子的用户 [英] How can i retreive the user who posted the post

问题描述

我正在通过开发一个小型博客来学习laravel.我已经创建了所有必要的关系.但是我无法获得最初创建该帖子的用户的姓名.

I am learning laravel by developing a small blog. I have created all the necessary relationships. But i am unable to get the name of the user who created the post originally.

我尝试过

$post->user->name;

但这会返回 null ，但是如果我这样做

but this returns null, however if I do

$post->user->id

它返回创建帖子的用户的ID

it returns the id of the user who created the post

我的帖子模型具有这种关系

My post model has this relationship

# Post.php

public function user()
{
    return $this->belongsTo('App\Post');
}

我的用户模型具有这种关系

My user model has this relationship

# User.php

public function posts()
{
    return $this->hasMany('App\Post');
}

我想要的结果是，如果我写

the results that i want is that if i write

$post->user->name

它应该显示用户名

现在，通过使用以下语句，我得到了类似的结果:

Right now im getting similar results by using this statement:

{{ \App\User::find($post->user_id)->name  }}

推荐答案

修正您的关系定义. Post 模型应指向 User 模型:

Fix your relationship definition. The Post model should point the User model:

use App\User; // <----

// ...

public function user()
{
    return $this->belongsTo(User::class);
}   //                      ^^^^^^^^^^^

此外，您不应该直接从前端进行查询，而是尝试急于加载背面的关系，然后将对象返回视图:

Also, you shouldn't do queries directly from the frontend, instead, try eager loading the relationship in the back and and then return the object to the view:

public function show(Request $request)
{
    $post = Post::with('user')->find(1);
    //            ^^^^^^^^^^^^
    return view('my_view')->with('post', $post);
}

然后在您的视图中，您直接使用该对象:

Then in your view you just use the object directly:

<h1> {{ $post->user->name }} </h1>
