Work in progress inspired by @HipsterJazzbo but app about to go live so needed something I was in control of.
Add Service Provider
'Warksit\Tenant\TenantServiceProvider',
Add Facade
'Tenant' => 'Warksit\Tenant\TenantFacade',
use WarksIt/tenant/TenantTrait;
in models to scope then by the tenant_id
Publish config and update models and then an observer is set in the ServiceProvider. I found boot method of Eloquent model too unreliable to set there.
php artisan config:publish Warksit/tenant
