问题:我在Size.php模型中有访问器,与Item.php模型有关联,在API中我需要访问器才能工作,但是在其他控制器中我想禁用访问器。我已从所有文件中删除了不必要/无关的代码。
我想做什么:

Size.php(模型)
class Size extends Model
{
protected $appends = ['addons'];
public function items()
{
return $this->belongsToMany('App\Item', 'items_sizes')->withPivot('price');//->withTimestamps();
}
public function getAddonsAttribute($value)
{
$addon = Addon::where('addons.category_id', $this->category_id)
->where('size_id', $this->id)
->get();
return $addon;
}
}
Item.php(模型)
class Item extends Model
{
public function options()
{
return $this->belongsToMany('App\Option', 'items_options')->withTimestamps();
}
public function sizes()
{
return $this->belongsToMany('App\Size', 'items_sizes')->withPivot('price');//->withTimestamps();
}
}
ItemControllerAPI.php(控制器)
class ItemControllerAPI extends BaseControllerAPI
{
public function show($id)
{
// If i call the Size model directly by using setAppends([]) its working fine,
// its removing the appended array from Size model
// $size = Size::all();
// $size->each->setAppends([]);
// return $size;
// If i use it with relationship it won't work.
// $itemSingleQuery = Item::with(['sizes' => function($query)
// {
// Doesn't work
// $query->setAppends([]);
// Doesn't work
// $query->each->setAppends([]);
// }])
// ->with('options')
// ->where('id', $id)
// ->get();
// query for getting data with relationships
$itemSingleQuery = Item::with('sizes')
->with('options')
->where('id', $id)
->get();
return $this->respondSuccess('content found', $itemSingleQuery);
}
}

我发现了如何做到这一点:
获取整个集合后,我们需要在每个包含附件的模型中调用setAppends()
,以在序列化为数组或JSON之前添加或删除它们。
$itemSingleQuery = Item::with('sizes')->get();
$itemSingleQuery->each(function ($item) {
$item->sizes->each->setAppends(['addons']);
});

我建议您在需要时设置__rust_dealloc
:
$appends
