Php 尝试获取laravel 5.2中非对象的属性

这是我的帖子表

    <?php
    use Illuminate\Database\Schema\Blueprint;
    use Illuminate\Database\Migrations\Migration;
    class CreatePostsTable extends Migration
    {

    public function up()
    {
        Schema::create('posts', function (Blueprint $table) {
            $table->increments('id');

            $table->integer('user_id')->unsigned();
            $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');

            $table->integer('prf_id')->unsigned();
            $table->foreign('prf_id')->references('id')->on('profiles')->onDelete('cascade');

            $table->longText('status');
            $table->timestamps();
        });
    }


    public function down()
    {
        Schema::drop('posts');
    }
}

帖子中
尝试以下代码：

public function profile(){
    return $this->belongsTo('App\Profile', 'prf_id');
}

显示正在获取的代码。
$status
？'public function myprofile（Request$Request）{$id=$Request->prf；$user=user:：where（'id'，'='，$id）->first（）；$u-id=$user->user\u-id；$all=Profile:：where（'id'，'='，$id）->first（）；$tasks=tasks:：where（'user\id'，'='，$u-id）->get（）；$user=user:：where（'id'，'id'，'id'，'$statuses=Post:：all（）；返回视图（'pages.profile'，compact（'all'，'tasks'，'user'，'statuses'）；}'@leo作为问题中的编辑。您的数据库未使用表配置文件的de默认键，能否显示de表键id？belongsTo（'App\Profile'）尝试使用Profile\u id而不是prf\u id
<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Profile extends Model

    protected $fillable = ['user_id','name','position','roles','username','college','phone','location','graduation','skill'];


    protected $hidden = [];

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

     public function posts(){

}

public function profile(){
