Laravel: Hide attributes from model just in some routes
提问by CanKer DiAlike
how do I hide some attributes from the model in just some routes, for example:
如何仅在某些路由中隐藏模型中的某些属性，例如：
I'm using protected $hidden to hide elements but this hide in all my functions or restful routes (index, show)
我正在使用 protected $hidden 来隐藏元素，但这隐藏在我的所有功能或宁静路线中（索引、显示）
$hidden = [
'coachVisibility', 'thumbnail', 'studentVisibility',
'isHTML', 'studentIndex', 'coachIndex',
'isURL', 'source', 'path',
'status', 'updateTime', 'isfolder',
'parentResource', 'idModifierUser', 'idResourceType',
'idCreatorUser', 'idCreationCountry', 'user',
'country', 'resource'
];
I want to hide only in Index function but in show function I don't want to hide anything.
我只想在 Index 函数中隐藏，但在 show 函数中我不想隐藏任何东西。

You can use the addHiddenmethod on the models:
您可以addHidden在模型上使用该方法：
class UsersController
{
public function index ()
{
return User::all()->each(function ($user) {
$user->addHidden([.........]);
});
}
}
Once this PRgets merged, you'll be able to call it directly on the collection:
一旦这个 PR被合并，你就可以直接在集合上调用它：
class UsersController
{
public function index ()
{
return User::all()->makeHidden([.........]);
}
}
According to your comment, you can keep all of those fields in the $hiddenproperty of your model, and instead make them visible only in the showmethod:
根据您的评论，您可以将所有这些字段保留在$hidden模型的属性中，而是仅在show方法中使它们可见：
public function show($id)
{
return CTL_Resource::where('idResource', $id)
->with('tags', 'quickTags', 'relatedTo')
->firstOrFail()->makeVisible([
'coachVisibility', 'thumbnail', 'studentVisibility'
]);
}

Consider using Transformers to transform return data as you would like.
考虑使用 Transformers 根据需要转换返回数据。
For eg:
例如：
Create an abstract Transformer:
创建一个抽象的 Transformer：
namespace App\Transformers;
abstract class Transformer
{
public function transformCollection(array $items)
{
return array_map([$this, 'transform'], $items);
}
public abstract function transform($item);
}
Then create custom transformers for each method if you like:
如果您愿意，然后为每种方法创建自定义转换器：
namespace App\Transformers;
use App\User;
class UserTransformer extends Transformer {
public function transform($user) {
return [
'custom_field' => $user['foo'],
'another_custom_field' => $user['bar']
...
];
}
}
Then in your controller:
然后在您的控制器中：
...
public function index(Request $request, UserTransformer $transformer)
{
$users = User::all();
return response()->json([
'users' => $transformer->transformCollection($users->toArray())
], 200);
}
There are a couple of advantages to this:
这样做有几个优点：
- You can show/hide data as you wish with specific transformers
- In-case you decide to change the column names in your table, your transformers will ensure that clients getting your data will not break.
- 您可以根据需要使用特定转换器显示/隐藏数据
- 如果您决定更改表中的列名，您的转换器将确保客户端获取您的数据不会中断。
