Pitch about the main idea of the project (Portuguese)

Context of the origin of the library proposal

• Video Part 1
• Video Part 2:

What is

This library makes it possible to use tenant strategies in a django project.

In a multi-tenant architecture, multiple instances of an application share the environment. This architecture is able to work because each tenant is physically integrated but logically separate; which means that a single instance of the software will run on a server and then service multiple tenants (clients).

The dango ultratenant library that implements diferent approaches.

Type of the Strategies (Approaches)

• multi-db
• multi-schema
• tenant-id

What is multi-db?

• Support multiple databases. Suported sqllite and postgresdb.

What is multi-schema?

What is tenant-id?

• Supported URL approaches: subdomain and path
  • tenant.url.com
  • url.com/tenant/admin/

Objectives

• In a django project implemented diferent approaches based of the bussiness core

• Simple API with minimal setup

• Transparent for the application

• Supported isolations approaches (multi-db, multi-schema, tenant-id)

How to Use

Installation

pip install django-ultratenant

Configuration

In the settings.py file, install the app that corresponds to the chosen strategy:

...
    INSTALLED_APPS=["test_project.singledb", "test_project.multidb"],
...

Put the information the created databases:

...
     DATABASES={
            "default": config("DATABASE_URL", default="sqlite://:memory:", cast=dburl),
            "t1": config("DATABASE_URL", default="sqlite://:memory:", cast=dburl),
            "t2": config("DATABASE_URL", default="sqlite://:memory:", cast=dburl),
        },
...

API Multi-db

...
    # settings.py
    from ultratenant.multidb import Databases
    ...
    MIDDLEWARE = [
        ...
        'ultratenant.path.Middleware',
    ]
    ...
    DATABASES = Databases(config('DATABASE_URL', cast=dburl))
    DATABASE_ROUTERS = ['ultratenant.multidb.Router']
...

set the urls depending on the chosen strategies

...
    # urls.py
    ...
    from ultimate_tenants.urls import tenants_path

    urlpatterns = tenants_path([
        path('admin/', admin.site.urls),
        path('', index, name='index'),
    ])

    # url.com/tenant/admin
