Campaign在我的Laravel 8 專案中我有一個名為專欄對此并不重要。
我想在我的Campaign模型中添加一些默認的鍵/值對，例如：dropdown_is_open并且應該有一個默認值false。
我遇到了模型的默認屬性并嘗試添加它，但在物件上看不到我的新鍵，我錯過了什么？
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
class Campaign extends Model
{
use HasFactory, SoftDeletes;
/**
* Indicates if the model's ID is auto-incrementing.
*
* @var bool
*/
public $incrementing = false;
/**
* The table associated with the model.
*
* @var string
*/
protected $table = 'campaigns';
/**
* The attributes that are mass assignable.
*
* @var array<int, string>
*/
protected $fillable = [
'campaign',
'template'
];
/**
* The model's default values for attributes.
*
* @var array
*/
protected $attributes = [
'dropdown_is_open' => false
];
}
控制器中的索引功能：
/**
* Display a listing of the resource.
*
* @return \Illuminate\Http\Response
*/
public function index()
{
$campaigns = Campaign::where('user_id', Auth::id())
->orderBy('created_at', 'desc')
->get();
if (!$campaigns) {
return response()->json([
'message' => "You have no campaigns"
], 404);
}
return response()->json([
'campaigns' => $campaigns
], 200);
}
我希望看到：
{
campaign: 'my campaign',
template: '',
dropdown_is_open: false <-- my key
}
Previously I was doing a foreach in my index function and adding the contextual keys on each item, but this would only show for the index function and I'd have to add it everywhere.
uj5u.com熱心網友回復：
我希望下面的內容有所幫助。
將其更改
my_custom_field為dropdown_is_open鍵（并從更改getMyCustomFieldAttribute為getDropdownIsOpenAttribute方法名稱）。
自定義屬性（或訪問器）
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class User extends Model {
protected $appends = ['my_custom_field'];
public function getMyCustomFieldAttribute()
{
return false;
}
}
僅需要上述
$appends內容，以確保my_custom_field已預設/快取，甚至作為 JSON-Response 發送。
