我有一个Laravel模型,它在我的登台服务器中返回字符串值而不是整数。 我决定通过cast属性的值来获得总是整数的值。Laravel雄辩属性Casting不起作用
我报我的模型:
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
class PressReviewPreset extends Model
{
/**
* Use soft delete
*/
use SoftDeletes;
/**
* The database table used by the model.
*
* @var string
*/
protected $table = 'pr_preset';
/**
* The attributes that should be mutated to dates.
*
* @var array
*/
protected $dates = ['deleted_at'];
/**
* The attributes that should be casted to native types.
*
* @var array
*/
protected $casts = [
'id' => 'integer',
'user_id' => 'integer',
'is_default' => 'integer',
];
/**
* The database field "updated_at" of table with a custom name
* @var string
*/
const UPDATED_AT = 'last_update';
/*
|---------------------------|
| Aliases for attribute |
|---------------------------|
*/
// Id
public function getIdAttribute()
{
return $this->attributes['id'];
}
public function setIdAttribute($id)
{
$this->attributes['id'] = $id;
}
// UserId
public function getUserIdAttribute()
{
return $this->attributes['user_id'];
}
public function setUserIdAttribute($user_id)
{
$this->attributes['user_id'] = $user_id;
}
// Default
public function getDefaultAttribute()
{
return $this->attributes['is_default'];
}
public function setDefaultAttribute($is_default)
{
$this->attributes['is_default'] = $is_default;
}
// ...
}
当我叫我的MacBook的工匠修补匠属性我得到这个结果:
>>> $p = App\Models\PressReviewPreset::first()
=> App\Models\PressReviewPreset {#810
id: 41,
user_id: 391,
name: "DEMO",
is_default: 1,
last_update: "2017-03-10 14:32:39",
created_at: "2017-03-10 14:27:24",
deleted_at: null,
}
>>> $p->id
=> 41
>>> $p->user_id
=> 391
>>> $p->userId
=> 391
>>> $p->is_default
=> 1
>>> $p->default
=> 1
所有的值都是正确的整数。
但是,如果我把我的临时服务器上相同的属性我得到这个结果:
>>> $p = App\Models\PressReviewPreset::first()
=> App\Models\PressReviewPreset {#810
id: "41",
user_id: "391",
name: "DEMO",
is_default: "1",
last_update: "2017-03-10 14:32:39",
created_at: "2017-03-10 14:27:24",
deleted_at: null,
}
>>> $p->id
=> "41"
>>> $p->user_id
=> "391"
>>> $p->userId
=> "391"
>>> $p->is_default
=> 1
>>> $p->default
=> "1"
为什么user_id
没有正确铸造成整数?
我做错了什么?
在此先感谢!

@EddyTheDove我很好奇,因为我以前遇到过同样的问题......尽管您链接的线程可能会详细说明问题的根源,但是在模型填充后,Laravel的投射功能是否应该确保值正确地进行了类型转换? – alaric
作为解决方法,顽强的您是否尝试过使用setXxxAttribute函数来转换值? – alaric
