你好,我正在尝试更改如何在不更改名称的情况下访问数据库列名,例如,我的列名是resourceType
,但我想称其为name,并且我希望响应json显示为name
而不是resourceType
。环顾互联网,我发现我应该使用protected $maps = ['oldName' => 'newName'];
,但不起作用。我想更改resourceType
,因为我认为表名应该等于列resourceType->resourceType
看起来不太好
这是我的型号
<?php
namespace Knotion;
use Illuminate'Database'Eloquent'Model;
use Mappable, Mutable;
class CTL_ResourceType extends Model {
public $timestamps = false;
protected $table = "CTL_ResourceType";
protected $primaryKey = "idResourceType";
public $incrementing = false;
public static $snakeAttributes = false;
protected $hidden = ['idCountry', 'idCompany', 'initials', 'thumbnail', 'icon', 'status', 'createTime', 'updateTime'];
protected $fillable = ['name'];
protected $maps = ['resourceType' => 'name'];
protected $appends = ['name'];
public function resource() {
return $this->hasMany('Knotion'CTL_Resource', 'idResource' );
}
public function country() {
return $this->belongsTo('Knotion'CTL_Country', 'idCountry', 'idCountry');
}
public function company() {
return $this->belongsTo('Knotion'CTL_Company', 'idCompany', 'idCompany');
}
}
这是我收到的响应JSON。正如你所看到的resourceType
剧照,而不是name

我以前没有听说过$maps
属性或Mappable
,所以我做了一个快速搜索。看起来它们(以及Mutable
)是jarektkaczyk/雄辩软件包的一部分。
在这种情况下,Mappable
和Mutable
都是应该添加到类中的特征。此外,为了使它们正常工作,您还需要添加Eloquence
特性。
文件顶部的use
语句需要更改,以正确地寻址正确名称空间中的类名,然后需要将特征添加到类中:
<?php
namespace Knotion;
// import the class names
use Sofa'Eloquence'Mutable;
use Sofa'Eloquence'Mappable;
use Sofa'Eloquence'Eloquence;
use Illuminate'Database'Eloquent'Model;
class CTL_ResourceType extends Model {
// add the traits to the class
use Eloquence, Mappable, Mutable;
// code...
}
编辑
如果你想在没有包的情况下做到这一点,你需要做三件事:
您需要将
resourceType
添加到$hidden
数组中,这样它就不会显示在toArray()
/toJson()
结果中。protected $hidden = ['idCountry', 'idCompany', 'initials', 'thumbnail', 'icon', 'status', 'createTime', 'updateTime', 'resourceType'];
您需要创建一个
getNameAttribute()
访问器方法,每当您尝试访问name
属性时,都会调用该方法。public function getNameAttribute() { return $this->resourceType; }
您需要将
name
添加到$appends
数组中,以便它将包含在toArray()
/toJson()
结果中。protected $appends = ['name'];
可选地,如果这感觉工作量太大,您可以始终覆盖toArray()
方法(由toJson()
调用)来强制执行命名约定,以及:
public function toArray() {
// call parent method to get initial array results
$array = parent::toArray();
// set the new key with data
$array['name'] = $array['resourceType'];
// unset the old key
unset($array['resourceType']);
// return the array
return $array;
}
