laravel - Dynamically hide certain columns when returning an Eloquent object as JSON?

Question

How do dynamically hide certain columns when returning an Eloquent object as JSON? E.g. to hide the 'password' column:

$users = User::all();
return Response::json($users);

I'm aware I can set protected properties in the model ($hidden or $visible), but how do I set these dynamically? I might want to hide or show different columns in different contexts.

Answer 1

$model->getHidden();
$model->setHidden(array $columns);

$model->setVisible(array $columns);
