Multi-Database Tenant Package for Laravel

This package is meant for Laravel applications to help with Multi-Database Tenant Applications.

A sample laravel application that uses this package can be found at github

Installation

composer require rndwiga\MultiTenant

Add the service providers to your application providers array in config/app.php A Facade is also available and can be added...

Providers

rndwiga\MultiTenant\LaraMultiDbTenantServiceProvider::class

Facade

'LaraMultiDbTenant' => rndwiga\MultiTenant\Facade::class

Configuration Files

php artisan vendor:publish

This will copy the laramultidbtenant.php configuration file into the app/config directory as well as copy the tenant, tenant_users and tenant_databases migration files needed. Create your models.

Setup the database for your Tenants in your .env files

Create the needed model classes

This will create the Tenant, TenantDatabase, TenantUser models. Make sure to provide the right relationships and don't forget to create the relationships within the User, Tenant, TenantUser and TenantDatabase models as well as set the connection properties.

php artisan tenant:basemodels

class Tenant extends Model
{
    protected $connection = 'todo';

    protected $table = 'tenants';

    protected $primaryKey = 'tenant_id';

    protected $fillable = ['tenant_uid', 'company_name', 'short_company_name', 'database_prefix', 'address'];
    .......

Create the template, tenant migration folders as well as a tenant public folder

php artisan tenant:folders

This package registers a middleware called authTenant within it's service provider. This is needed in order to automatically set the default connections for the Application's model

For a todo application see demo application

Inside your controllers that will control tenant specific routing, add the following to the __construct methods

$this->middleware('auth');
$this->middleware('authTenant'); //This is automatically pushed to laravel's kernel

also make sure to include the trait to do migrations automatically once the tenant has registered their company...

use MigrateTenantDatabase;

Complete namespace for this is...

use rndwiga\MultiTenant\Traits\MigrateTenantDatabase;

Create your migration files

This assumes you have already done...

php artisan vendor:publish

So create your migration files...

php artisan make:migration create_todo_table --create=todos --path=database/migrations/tenant

Your TenantDatabase Model

This is important

Your TenantDatabase model must implement the ITenantDatabase interface

class TenantDatabase extends Model implements ITenantDatabase

Once that's done, start with registering a user, at least collect information needed. In your controller that registers the user, tenant, tenant_database, tenant_users you should be able to do...

$this->migrateTenantDatabase($tenantDatabase->hostname, $tenantDatabase->database_name, $tenantDatabase->user_name, $tenantDatabase->password);

Use this demo as a guide. See SessionsController@postRegister. This should show the code...

    $input = $request->all();
    $email = $input['email'];
    $password = $input['password'];
    $name = $input['name'];
    $companyName = $input['company_name'];

    DB::beginTransaction();

    $user = $this->registerUser($email, $password, $name);
    $tenant = $this->registerTenant($companyName);
    $tenantUser = $this->createTenantUserDetails($user, $tenant);
    $tenantDatabase = $this->createTenantDatabase($tenant);

    DB::commit();
    //now we can migrate the database of the tenant using the tenant database settings

    $this->migrateTenantDatabase($tenantDatabase->hostname, $tenantDatabase->database_name,
                                     $tenantDatabase->user_name, $tenantDatabase->password);
