php - Laravel 用户只有一个计划，通过关系访问该计划

Question

我的用户模型：

<?php

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
    use Notifiable;

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

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

    public function plan()
    {
        return $this->hasOne('App\Plan');
    }
}

我plan_id在用户表中作为外键，它指的是plan表中的 id。

当我访问时，User::with('plan')->get();我无法获得计划，我错过了什么？

如果您在用户表中有plan_id 作为外键，则指的是计划表中的id。

<?php

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
    use Notifiable;

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

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

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