dj-multidomain

Dynamic Multi-Domain Middleware for Django

dj-multidomain is a powerful Django middleware that enables dynamic routing of requests to different URL configurations based on the domain of incoming requests. It also supports automatic redirection for specific domains and provides options for shared common URLs. This middleware is ideal for projects hosted across multiple domains or with subdomain-specific functionalities.

Features

• Domain-Based URL Routing: Route requests to different URL configurations based on the domain.
• Subdomain Handling: Easily manage subdomains and inject subdomain data into requests.

Installation

1. Install the Package

Install dj-multidomain using pip:

pip install dj-multidomain

Ensure publicsuffix2 is also installed:

pip install publicsuffix2

2. Add Middleware

In your settings.py, add the middleware to the MIDDLEWARE list:

MIDDLEWARE = [
    ...
    'dj_multidomain.middleware.MultipleDomainMiddleware',
    ...
]

---

Configuration

1. Map Domains to URL Configurations

Use MULTI_DOMAIN_CONFIG to map domains to their respective URL configuration files. Add this to settings.py:

MULTI_DOMAIN_CONFIG = {
    'example.com': 'project.urls_example_com',
    'example.org': 'project.urls_example_org',
}

2. Redirect Domains (Optional)

If you want to redirect specific domains to others, use MULTI_REDIRECT_CONFIG:

MULTI_REDIRECT_CONFIG = {
    'www.example.com': 'example.com',
    'oldsite.org': 'newsite.org',
}

3. Add Common URLs (Optional)

Define shared URLs that are accessible from any domain using COMMON_URLS:

COMMON_URLS = 'project.urls_common'

4. Subdomain Configuration (Optional)

If subdomain data needs to be injected into requests, use MULTI_SUBDOMAIN_CONFIG to define parameter names:

MULTI_SUBDOMAIN_CONFIG = ['subdomain1', 'subdomain2']

5. Default Domain (Optional)

Set a fallback URL configuration for unrecognized domains (only active in DEBUG mode):

DEFAULT_DOMAIN = 'example.com'

Example Usage

1. Domain-Specific URL Configuration

Create domain-specific URL files, e.g., urls_example_com.py:

from django.urls import path
from . import views

urlpatterns = [
    path('', views.home, name='home'),
    path('about/', views.about, name='about'),
]

2. Common URL Configuration

Define shared URLs in urls_common.py:

from django.urls import path
from . import views

urlpatterns = [
    path('contact/', views.contact, name='contact'),
]

3. Subdomain Handling

Subdomains will be available as attributes in the request object. For example:

def subdomain_example(request):
    subdomain1 = getattr(request, 'subdomain1', None)
    return HttpResponse(f"Subdomain 1: {subdomain1}")
