Causer Resolver

The CauserResolver class handles resolving who caused an activity. It is registered as a scoped binding (per request) in the container.

For most use cases, you should use the Activity facade instead of interacting with CauserResolver directly:

use Spatie\Activitylog\Facades\Activity;

// Scoped causer (recommended)
Activity::defaultCauser($admin, function () {
    // all activities here will have $admin as causer
});

// Global causer
Activity::defaultCauser($admin);

##Advanced usage

If you need lower-level control, resolve the CauserResolver from the container:

use Spatie\Activitylog\Support\CauserResolver;

// Custom resolution callback
app(CauserResolver::class)->resolveUsing(function ($subject) {
    return User::find(1);
});

Note: setCauser() takes priority over resolveUsing().
