无法访问 Laravel 模型中的属性

Question

目前我已经为数据库做了一个默认模型user_domains

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Domains extends Model
{
    public $incrementing = true;
    protected $table = 'user_domains';
    protected $primaryKey = 'id';

}

到目前为止，还不错。

但是，当我使用查询生成器从中获取一些数据时，它不允许我通过属性访问它，例如 $domains->domain

我做了一个函数，这个函数使用 all 方法来获取所有数据，没有任何困难的 where-statements。但是，这个输出是一个巨大的集合，包含数据库的每个细节

      array(1) {

        string(1) "*"
      }
    }
  }
}

我怎样才能访问 table 中的数据，而不是所有这些垃圾？

Answer 1

$domains 是 Domains 的 Collection。不只是一个 Domain.
您正在尝试从此 Collection.

访问 Domain 对象的 attribute

由于您没有在问题中发布您尝试做的事情，我无法提供解决方案。

但我会分享一些知识。

从集合中获取一个元素，然后您可以访问该对象的属性。

// name of the first domain (string)
$name = $domains->get(0)->name;

将所有名称获取到另一个集合

// names of all the domains (another collection)
$names = $domains->map->name;
