README

Easily add multitenancy capabilities to your Symfony projects without (too much) code modification.

Installation

Prerequisites

We assume you have a DATA_PATH environment variable to store all data, including database data and other data types such as files.

We assume you have a DATABASE_URL environment variable containing the general path to your database.

Install

Install the package using Composer:

composer require phariscope/multitenant

You can use Multitenant as a Symfony bundle. Simply add one line to your config/bundles.php file:

return [
    // other bundles

    Phariscope\MultiTenant\MultiTenantBundle::class => ['all' => true],
];

Usage

Use either the brute force or the precise method.

With the brute force method: Your entire application will be tenanted: it will be very difficult to implement any part external to your application, as the original DATA_PATH and DATABASE_URL env will be lost.

With the precise method: Choose where to implement tenant behavior or general behavior.

Brutal

Modify DATA_PATH and DATABASE_URL values as soon as possible with the ContextTransformer. You won't have to think about tenants anymore because your EntityManager object will be build with your tenant values.

For instance with Symfony, inside your console script or your index.php, just modify the contexte.

In a typical console script:

return function (array $context) {
    $o = new ContextTransformer($context);
    $o->transformDataPath();
    $o->transformDatabaseUrl();

    $kernel = new Kernel($context['APP_ENV'], (bool) $context['APP_DEBUG']);

    return new Application($kernel);
};

in your Symfony Commands YOU MUST allow --id_tenant option like this

class YourOwnCommand extends Command
{
(...)

    protected function configure(): void
    {
        $this
            ->setName('my:own:command')
            ->setDescription('This is a sample command description.')
            ->addOption('tenant_id', null, InputOption::VALUE_REQUIRED, 'The ID of the tenant');
    }
(...)

Important : if you don't require tenant_id then when you ignore --tenant_id the orignal DATA_PATH and DATABASE_URL values are used. (so this is a way to have a global comportement; you can be "precise" anyway)

Precise

In a Symfony controller, follow these steps:

1. Inject EntityManagerResolver into your controller’s constructor.
2. Retrieve the tenant-specific entity manager within your route action.
3. create database and schema for a tenant if database does not exist for this tenant

For example, assuming you have a tenant_id in your request or session:

class YourController extends AbstractController
{
    public function __construct(
        private EntityManagerResolver $entityManagerResolver,
    ) {}

    #[Route('your/route', name: 'runYourRoute', methods: ['POST', 'GET'])]
    public function runYourRoute(Request $request): Response
    {
        $tenantEntityManager = $this->entityManagerResolver->getEntityManagerByRequest($request);
        (new DatabaseTools())->createDatabaseIfNotExists($entityManager);

        $repository = new YourSomeEntityDoctrineRepository($tenantEntityManager);

        // Your code here...
    }
}

Creating a Tenant Database

Ensure you have the necessary console setup to handle tenant operations.

To create a database for a specific tenant (e.g., tenantID1234), you can use the console command:

bin/console tenant:database:create --tenant_id tenantID1234

Creating a Schema for a tenant database

Once you have created a tenant database, you can create its schema.

You can use the console command:

bin/console tenant:schema:create --tenant_id tenantID1234

Updating the schema for a tenant database

When your entity mappings change, you can align the tenant database with the current metadata (similar to doctrine:schema:update).

Show the SQL without executing it:

bin/console tenant:schema:update --tenant_id tenantID1234 --dump-sql

Apply the changes:

bin/console tenant:schema:update --tenant_id tenantID1234 --force

Tenant shortname (tenant_shortname)

Applications can expose a human-friendly hostname or path segment (tenant_shortname) instead of the canonical tenant_id. Resolution uses a small SQLite registry stored next to tenant data:

• If DATA_PATH is the host root (e.g. ./var/data), the registry file is ./var/data/tenants/tenants.sqlite.
• If DATA_PATH already points to a tenant folder (e.g. ./var/data/tenants/tenantID1234), the registry is still ./var/data/tenants/tenants.sqlite (same file for all tenants).

Storage paths (DATA_PATH tenant suffix and SQLite DATABASE_URL rewriting) always use the resolved tenant_id, never the shortname string.

Supported inputs mirror tenant_id: query/body parameters, session keys, cookies, JSON body fields, and headers X-Tenant-Shortname / HTTP_X_TENANT_SHORTNAME. HTTP and ContextTransformer still resolve a shortname alone via tenants.sqlite.

When creating or provisioning a tenant, the registry is updated in tenants.sqlite:

• CreateTenantService: always writes a mapping (DATA_PATH required). If tenantShortname is omitted, the shortname stored equals tenant_id.
• Bundle console commands (tenant:database:create, tenant:schema:create, tenant:schema:update): --tenant_id is required. Optional --tenant_shortname registers a custom slug; if omitted, the shortname stored equals tenant_id. --tenant_shortname alone is rejected.

Console examples:

bin/console tenant:database:create --tenant_id tenantID1234
bin/console tenant:database:create --tenant_id tenantID1234 --tenant_shortname my-school
bin/console tenant:schema:create --tenant_id tenantID1234 --tenant_shortname my-school

How it works

A "tenants" subfolder will be created in the DATA_PATH. For each tenant, a specific folder will be created containing all the data, including the database.

For example:

DATA_PATH=./var/data
DATABASE_URL=sqlite:///%DATA_PATH%/eventually/some/subfolders/mydatabase.sqlite

Given the tenant "tenantID1234", the database create command will create the following file: ./var/data/tenants/tenantID1234/eventually/some/subfolders/mydatabase.sqlite

The "./var/data/tenants/tenantID1234" folder will contain all the data required for your project.
