A general purpose multi-tenancy package for Laravel 4.2+. Accidentally derived from the work of @tonydew, and with help from @rizqidjamaluddin

First off, this package assumes that you have a column on all of your tenant-scoped tables that references which tenant each row belongs to.

For example, you might have a companies table, and all your other tables might have a company_id column (with a foreign key, right?).

To get started, require this package in your composer.json and run composer update:

"aura-is-here/laravel-multi-tenant": "dev-master"

After updating composer, add the ServiceProvider to the providers array in app/config/app.php:

'AuraIsHere\LaravelMultiTenant\LaravelMultiTenantServiceProvider',

You'll probably want to set up the alias:

'TenantScope' => 'AuraIsHere\LaravelMultiTenant\Facades\TenantScopeFacade'

You could also publish the config file:

php artisan config:publish aura-is-here/laravel-multi-tenant

and set up your tenant_column setting, if you have an app-wide default.

First off, you'll have to call TenantScope::addTenant($tenantColumn, $tenantId) at some point. It could be as part of your login process, or in an OAuth setup method, or wherever.

You can also call TenantScope::addTenant($tenantColumn, $tenantId) again at any point to add another tenant to scope by.

Once you've got that all worked out, simply use the trait in all your models that you'd like to scope by tenant:

<?php

use AuraIsHere\LaravelMultiTenant\Traits\TenantScopedModelTrait;

class Model extends Eloquent {

    use TenantScopedModelTrait;
}

Henceforth, all operations against that model will be scoped automatically.

You can also set a $tenantColumns property on the model to override the tenants applicable to that model.

$models = Model::all(); // Only the Models with the correct tenant id

$model = Model::find(1); // Will fail if the Model with `id` 1 belongs to a different tenant

$newModel = Model::create(); // Will have the tenant id added automatically

If you need to run queries across all tenants, you can do it easily:

$allModels = Model::allTenants()->get(); //You can run any fluent query builder methods here, and they will not be scoped by tenant

When you are developing a multi tenanted application, it can be confusing sometimes why you keep getting ModelNotFound exceptions.

Laravel Multi Tenant will catch those exceptions, and re-throw them as ModelNotFoundForTenant, to help you out :)

Please! This is not yet a complete solution, but there's no point in all of us re-inventing this wheel over and over. If you find an issue, or have a better way to do something, open an issue or a pull request.
