英文:
append attribute to resurce from resource::make in laravel
问题
I am trying to build a laravel api route to return users data. I got some data stored in txt file. To avoid accessing txt many times, the txt file is read in controller but not in resource.
然而，当我使用UserResource::make($user)和UserResource::collection($user)后，我无法给资源的返回分配一些其他属性。
I want to do something like this:
我想要做类似于这样的事情：
$newAttr = $myFileReader->read(abc.txt) //search and return the attr I need
$user_rsc = UserResource::make($user);
$user_rsc['newAttr'] = $newAttr;
return $user_rsc; // the result does not have the newAttr in my case
Is it possible to append attribute after resource::make?
在使用resource::make之后是否有可能追加属性？
I had try this $user_rsc->additional(['tag' => "haha"]); before, it does not work in my case.
我之前尝试过$user_rsc->additional(['tag' => "haha"]);，但在我的情况下没有起作用。

得分: 1
我发现从 UserResource::make() 返回的对象是不可变的。我无法通过 additional() 和 with() 方法解决这个问题。最终，我决定暂时采用一个不好的做法来解决它：
以下是解决方案：
$user_rsc = UserResource::make($user)->toArray($request);
$user_rsc['tag'] = $tags;
这个想法是将资源转换为数组，然后附加新属性。
我相当确定这不是一个合适的方法。
英文:
I found that the object returned from UserResource::make() is immutable. And I cannot solve it by additional() and with(). Finally, I decide to use a bad practice to solve it temporarily:
Here is the solution:
$user_rsc = UserResource::make($user)->toArray($request);
$user_rsc['tag'] = $tags;
The idea is to convert the resource to array and append new attribute.
I am pretty sure this is not a proper way.
