Laravel Multi Tenant

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

Installation

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.

Usage

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?).

Next, you'll have to call TenantScope::addTenant($tenantColumn, $tenantId). It doesn't matter where, as long as it happens on every request. This is important; if you only set the tenant in your login method for example, that won't run for subsequent requests and queries will no longer be scoped.

Some examples of good places to call TenantScope::addTenant($tenantColumn, $tenantId) might be:

• In a global Middleware
• In an oauth system, wherever you're checking the token on each request
• In the constructor of a base controller

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 :)
