laravel - 从 Laravel 中的 db 获取一项

问题描述

显示这种“行为”是很奇怪的，因为我以前做过，但这里是：我试图在 Laravel 中显示来自 db 的特定记录。

到目前为止，这是我的代码：

工作模式：

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;
use App\User;

class Job extends Model
{
    protected $fillable = [
        "title", "description", "email"
    ];

    public function user(){
        return $this->belongsTo("App\User","user_id");
    }

}

用户型号：

<?php

namespace App;

use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use App\Role;

class User extends Authenticatable
{
    use Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'email', 'password',"role_id"
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];

    public function role(){
        return $this->belongsTo("App\Role", "role_id");
    }

    public function job(){
        return $this->hasMany("App\Job");
    }

并在 JobController 中显示方法：

public function show(Job $job)
    {
        $jobx = Job::find(4)->get();
        dd($jobx);
        return view("jobs.show")->with(compact("jobx"));
    }

show 方法中的参数是数组，但应该是数字（id）。但我可以在网址中清楚地看到一个数字。它从哪里得到这个数组，为什么？另外如何纠正 show 方法以便它可以获取 id？

还php artisan route:list显示作业而不是id作为路由中的参数：
