Laravel Eloquent（模型属性不会显示）

Question

我有一个 Stat Class :

class Stat extends Model
{
    public static function getByKey($key)
    {
        return Stat::where("key", "=", $key)->first();
    }

    public function getDates()
    {
        return json_decode($this->content);
    }
}

在我的数据库中，Table stats 仅包含两列（键、内容）当我在我的视图中执行此功能时发生错误

{!! \App\Stat::getByKey("ORDERS-DATA")->getDates() !!}

这会导致此错误：

Exception message: Undefined property: App\Stat::$content

所以我将这两行添加到 getDates() 来调试错误：

public function getDates()
{
    dd($this->content);//This shows the same error
    dd($this->attributes["content"]);//This works fine and show me what I want
    return json_decode($this->content);
}

然后我执行了 dd($this) 它显示了这个：

Stat {#486
  #connection: "mysql"
  #table: "stats"
  #primaryKey: "id"
  #keyType: "int"
  +incrementing: true

  #perPage: 15
  +exists: true
  +wasRecentlyCreated: false
  #attributes: array:5 [
    "id" => 8
    "key" => "ORDERS-DATA"
    "content" => """
      [
      {
      \t"day": "2019-04-01",
      \t"count": "5"
      }
      ]
      """
    "created_at" => "2019-04-01 14:09:00"
    "updated_at" => "2019-04-01 14:11:02"
  ]
  #original: array:5 [
    "id" => 8
    "key" => "ORDERS-DATA"
    "content" => """
      [
      {
      \t"day": "2019-04-01",
      \t"count": "5"
      }
      ]
      """
    "created_at" => "2019-04-01 14:09:00"
    "updated_at" => "2019-04-01 14:11:02"
  ]
  #changes: []

  #dates: []
  #dateFormat: null
  #appends: []
  #dispatchesEvents: []

  #touches: []
  +timestamps: true
  #hidden: []
  #visible: []
  #fillable: []
  #guarded: array:1 [
    0 => "*"
  ]
}

而我想要的是通过 $this->content 获得我的 content，但我不明白为什么它不起作用？？请帮忙

发生错误是因为我覆盖了 Laravel 函数之一。名称 getDates OR getByKey OR getCounts 被 Laravel 使用。

This is so weird this error happened to me two times in the same day, Today's morning I created a function called getAttributes() and showed me a total diferrent error. Why the community don't create a list of functions names that we are not allowed to use, or use more unique names ???
