Question

我在Laravel之外使用雄辩的ORM。我对表和视图执行简单的CRUD操作，但我无法弄清楚如何遍历或设置关系。我试过这段代码

<?php

include 'eloquent_database.php';
class User extends Illuminate\Database\Eloquent\Model {
    public $timestamps = false;
    protected $table = 'user';
        protected $primaryKey = 'userId';

       public function company() {
           return $this->belongsTo('company', 'companyID');
       }
}  
// Create the company model
class Company extends Illuminate\Database\Eloquent\Model {
    public $timestamps = false;
    protected $table = 'company';
    protected $primaryKey = 'companyID';

    public function users()
    {
        return $this->hasMany('user', 'userId');
    }
}


// Grab all from company table
$companys = Company::all(); 


foreach ($companys as $company) {
        echo "<B>" .$company->name . "<br>";
        $users = $company->users();
        foreach($users as $user) {

            echo $user->userName . "<br>";
        }
};
?>

但我没有找回公司的任何用户。只是公司名称

Answer 1

就像@Cryode已经说过的那样：

$company->users(); // relation object
$company->users; // collection of related users

所以你需要后者。

然而，你的关系是错误的，所以无论如何它都不会起作用，直到你解决它如下：

// Company model
public function users()
{
    return $this->hasMany('user', 'companyId');
}

Answer 2

您使用的关系不正确。如果要返回关系的结果（即实际模型[s]），则调用属性，而不是方法。

// Will perform a query and return the results of the relationship.
$users = $company->users;

// Will return the relationship object you defined in your method. It's normal PHP, zero magic.
$usersRelationshipObject = $company->users();
