我以 UTC 格式保存所有日期时间数据(created_at、updated_at 和自定义日期时间列:约会_at)。
我想检索所有这些日期,并将它们转换为用户的时区以进行显示。
我已将这些函数添加到我的模型中,认为这将检索用户时区中的日期时间:
public function getCreatedAtAttribute($value)
{
return $created_at->timezone(Auth::user()->timezone);
}
public function getUpdatedAtAttribute($value)
{
return $updated_at->timezone(Auth::user()->timezone);
}
public function getAppointmentAtAttribute($value)
{
return $appointment_at->timezone(Auth::user()->timezone);
}
但我收到以下错误:
Call to a member function timezone() on a non-object
我猜我的语法有错误。我错过了什么吗?谢谢
更新 #1 对 Note Model 进行了更正,并在下面添加了完整的模型(包括@bernie 的更正)
<?php namespace App;
use Illuminate\Database\Eloquent\Model;
class Note extends Model {
/**
* The database table used by the model.
*
* @var string
*/
protected $table = 'notes';
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = ['client_id', 'business_id', 'note'];
/**
* Note belonging to client.
*
* @return \Illuminate\Database\Eloquent\Relations\BelongsTo
*/
public function client()
{
return $this->belongsTo('App\Client');
}
public function getCreatedAtAttribute($value)
{
return $this->created_at->timezone(Auth::user()->timezone);
}
public function getUpdatedAtAttribute($value)
{
return $this->updated_at->timezone(Auth::user()->timezone);
}
public function getAppointmentAtAttribute($value)
{
return $this->appointment_at->timezone(Auth::user()->timezone);
}
数据库模型定义
<?php
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateNotesTable extends Migration {
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('notes', function(Blueprint $table)
{
$table->increments('id');
$table->integer('client_id')->unsigned();
$table->foreign('client_id')->references('id')->on('clients')->onDelete('cascade');
$table->integer('business_id')->unsigned();
$table->foreign('business_id')->references('id')->on('businesses')->onDelete('cascade');
$table->text('note');
$table->dateTime('appointment_at');
$table->rememberToken();
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::drop('notes');
}
}

解决方案
public function getCreatedAtAttribute($value)
{
$date = $this->asDateTime($value);
return $date->timezone(\Auth::user()->timezone);
}
或者
public function getCreatedAtAttribute($value)
{
$format = $this->getDateFormat();
return Carbon::createFromFormat($format, $value, 'UTC')->setTimezone( \Auth::user()->timezone);
}
这两种解决方案都对我有用。
