[9.x] Add Model::withoutTimestamps(...)

[timacdonald]

Re-submission of #44005 as static methods.

API now matching the static nature of withoutTouching, but hopefully with a simpler implementation than previous attempts at this functionality.

$user = User::first();


// `updated_at` is not changed...

User::withoutTimestamps(
    fn () => $user->update(['reserved_at' => now()])
);

I suspect this implementation will not work as expected with nested calls to withoutTimestamps(). E.g.:

User::withoutTimestamps(function () use ($user) {

    User::withoutTimestamps(
        fn () => $user->update(['reserved_at' => now()])
    );
    
    $user->update([...]); // <-- Will update timestamps
});

You can imagine one would call withoutTimestamps() e.g. in a controller and then deeper somewhere in a model, in different contexts, which would lead to this situation. I think it should be fixed to be able to cope with this situation.

I don't think it was ever intended to work with nested calls? @timacdonald

[timacdonald]

I did not intend for it to be used this way. Would recommend not nesting calls to this or the other methods that work this way.

Yeah, I've run into this before. Disabling timestamps is a tricky beast and heavily dependent on the use case.

I had my own implementation of withoutTimestamps on trait that was working differently and I think the current approach is not very helpful.
The withoutTimestamps was a non static method that I was able to use on the existing model I am using or on an Eloquent Builder instance

On a single model

$model
    ->withoutTimestamps()
    ->update([
           'included' => true
      ]);

Updating all models by using a relationship

$tasks
            ->subTasks()
            ->tap(function (Builder $query) {
                $query->getModel()->withoutTimestamps();
            })
            ->update([
                'included' => false,
            ]);

Wouldn't both example be possible like this?

Model::withoutTimestamps(fn () => $model->update([ 'included' => true ]));

SubTask::withoutTimestamps(fn () => $task->subTasks()->update([ 'included' => false ]));

See @dennisprudlo suggestion above, and also see the previous PR where the method was not static for future discussion: #44005
