You dont need to set $append. If you dont, just can alywas just call $model->type to get the value (in a resource or similar)

How to call set $append attribute in manual way when need it?
I would like to know if I could actually set the $append attribute manually when i need it?
For example, in my model
$append = ['type']
public function getTypeAttribute($value) {
return .....
}
I have a resource which is sharing with other related response. I would like to control it to whether get this type attribute when return as a response. As i noticed, even i removed append, whenever i called $this->type in my resource i will still get the value.
How can i check if the attribute want to be included in the resources?

@Sinnbeck I have a case, which i am using a same resources for index() and edit(). I need this type attribute (this type is not related to database, just append by me manually) in my index() but not for the edit(). How should I remove it when I am with edit()? Or i have to create a new resource for it?

@zidance Well you need to find a way to find out if you want to append it. Perhaps check if it has an ID?

@Sinnbeck I guess I only can create a new resources if unable to make it like
For example in index() function,
$collections = Model::withAppend('type')->get()
For example in edit() function,
$collection = Model::find($id)
If there's no way to achieve something like this then i have to create separate resource for them.

@zidance what do you mean by resource? I assume api resource.

@Sinnbeck It's just simple where the resource return the attribute with type = $this->type, while actually the type here is not a database field. I just create an accessor for this type attribute and append within my model. So, whenever i query i will get this attribute, but then I would like to make it able to include or exclude when i query my result.
I think i am going to create new resource if there's no way can define in this way.

For example I use $appends (notice your error, append with an 's') to get calculated properties. As said by @sinnbeck, no need to use an appended property to access a field which is in the database.
But you say that this field is not in the database ?

@vincent15000 Yes, i append it to the model manually. It is not a field in the database.

@zidance @vincent15000 @sinnbeck Hi!, by the way did you do it?
i also have a model like this:
class ExampleModel extends Model {
// protected $appends = [`sample`]; // --> I DONT want this because it will going to append on every query I make using this model
public function getSampleAttribute() {
...
}
}
What I wanted was to be able to only append if I needed it.
for example:
ExampleModel::withAppend('sample')->get(); // data should have a sample attribute added although withAppend does not exist.
ExampleModel::get(); // data should not have sample attribute in it.
I am also trying to achieve, any tip and suggestion?

@JenuelDev-31676163 The appends protected property is only useful if you are using serialized models (like in APIs).
If you are developping a full blade frontend, you don't need to use the appends protected property and you will always need to call these properties manually.

@vincent15000 sorry, long time to reply. What I think the alternative I did was doing it this way. For the mean time its the only way I can do.
$list = ExampleModal::get()->map(function ($item) {
$item->sample = $item->sample; // the getSampleAttribute
return $item;
});

@JenuelDev-31676163 Why doing like this ? In the blade view, you just have to wode {{ $item->sample }}.
