在Laravel中为日期时间格式化的字段返回unix-timestamp格式 [英] return unix-timestamp format for datetime formatted field in laravel

问题描述

我有一个像这样的 Message 模型:

I have a Message model like this :

class Message extends Model
{
    protected $primaryKey = 'message_id';
    protected $dates      = ['created_at', 'updated_at', 'receiver_deleted_at', 'sender_deleted_at', 'sender_read_at', 'receiver_read_at'];
}

您会看到有些日期字段以 DATETIME(YYYY-MM-DD HH:MM:SS)格式保存日期.

As you can see there are some date fields that hold dates as DATETIME(YYYY-MM-DD HH:MM:SS) format.

但是我想在获取模型实例时将所有日期字段转换为 unix-timestamp 格式，然后返回.

But I want when get an instance of model all date fields convert to unix-timestamp format and then return.

我知道可以对每个字段使用这样的访问器:

I know that can use accessor like this for every field :

public function getCreatedAtAttribute()
{
    dd(strtotime($this->attributes['created_at']));
    return strtotime($this->attributes['created_at']);
}

但是在这种情况下，我必须为每个字段定义一个类似于上面的函数.

But in this case I must define a function like above for each field.

但是我想要一种更简单的方法来强制模型以unix-timestamp格式返回日期字段.

But I want an easier way that force model to return date fields as unix-timestamp format.

推荐答案

    protected $casts = [
    'created_at' => 'timestamp',
    'updated_at' => 'timestamp'
  ];

在模型中，只需添加这些演员表以获得unix时间戳

In model just add these cast to get unix timestamp
