Laravel user specific caching

Question

I've never done much with caching, but am trying to play around with it a bit now. I have a dashboard that returns a lot of data, and to make the load a bit lighter, I am caching data like so:

return cache()->rememberForever('something', function () {
    return auth()->user()->something()->get();
});

Where "something" is just a related model. When creating a new record, in the controller store and update methods I just do this:

cache()->forget('something');

This all works flawlessly. But when I login with another user, all cached data from the previous user is obviously being displayed on the dashboard.

Is there an easy way to simply cache data per user?

You could do something like this to store user object for each user separately:

return cache()->rememberForever('something' . auth()->id(), function () {
    return auth()->user()->something()->get();
});

To get the data for an authenticated user:

 cache('something' . auth()->id());
