Laravel 与 withCount() 有很多关系

Laravel hasmany relationship with withCount()

试图显示属于公司 table 的用户数 table 我只得到 NULL,而我在直接调用关系时通常可以看到正确的结果。这是显示代码:

@foreach($allCompanies as $theCompany)
{{ $theCompany->getUser_count }}
@endforeach

这是模型:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Companies extends Model {
    protected $table = 'companies'; 

    public function getUser(){
        return $this->hasMany('App\User', 'company_id');
    }
}

这是控制器:

$allCompanies   = Companies::withCount('getUser')->get();

当我调用 $theCompany->getUser 时,我得到了 json 个用户,但是 withCount returns 总是 NULL。

在变量名中使用 underscore 而不是 camelCase

@foreach($allCompanies as $theCompany)
    {{ $theCompany->get_user_count }}
@endforeach

更改代码

$allCompanies   = Companies::withCount('getUser')->get();

$allCompanies   = Companies::with ('getUser')->withCount('getUser')->get();
