問題描述
在使用 Laravel 的 Eloquent ORM 時，我似乎無法在模型上動態設置 $hidden 和 $visible 屬性.
When using Laravel's Eloquent ORM, I can't seem to set the $hidden and $visible properties on my Model dynamically.
示例 1:這有效:
class User extends Eloquent {
$this->visible = array('field_name');
function read()
{
return User::all();
}
}
示例 2:動態設置 Eloquent 類的可見屬性，不起作用:
class User extends Eloquent {
function read($visible = array('field_name'))
{
$this->visible = $visible; // Also tried: $this->setVisible($visible);
return User::all();
}
}
示例 3:適用于模型本身的解決方案，但不適用于急切加載的模型:
class User extends Eloquent {
function read($visible = array('field_name'))
{
$users = User::all();
return $users->get()->each(function($row) use ($visible) {
$row->setVisible($visible);
});
}
}
為了在 Eagerly Loaded Models 上動態設置 $visible 屬性，除了讓示例 2 工作之外，我沒有看到其他解決方案.但是如何?
In order to set the $visible property dynamically on Eagerly Loaded Models, I don't see another solution than to get Example 2 to work. But how?
推薦答案
由于 $visible 是在實例級別設置的(即它不是在同一類型的所有模型之間共享的靜態變量)，不 - 沒有更好的方法可以做到這一點.
As $visible is set on an instance level (i.e. it's not a static variable shared between all models of the same type), no - there's no better way to do this.
