django-namespaces 0.0.26

Add namespaces to your Django requests. Helps with project isolation.

django-namespaces

Use namespaces in requests using Django.

Motivation

With django-namespaces, we get a new way to group resources based on request.namespace.

Installation

Use a virtual environment whenever using Python packages. The built-in venv module is great.

python3 -m venv venv
source venv/bin/activate
$(venv) python -m pip install django-namespaces --upgrade

Django Settings (settings.py)

Installed Apps

Add django_namespaces to INSTALLED_APPS:

INSTALLED_APPS = [
    # ...
    "django_namespaces",
]

Middleware

Update MIDDLEWARE:

MIDDLEWARE = [
    # ...
    "django_namespaces.middleware.NamespaceMiddleware",
]

This gives us access to the request.namespace object in our views.

Template Context Processors

Add django_namespaces.context_processors.user_namespaces to TEMPLATE_CONTEXT_PROCESSORS:

TEMPLATE_CONTEXT_PROCESSORS = [
    # ...
    "django_namespaces.context_processors.user_namespaces",
]

Usage Usage

from django.contrib.auth import get_user_model
from django_namespaces.models import Namespace

User = get_user_model()
user = User.objects.create_user(username="jon.snow", password="youknowsomething")

namespace = Namespace.objects.create(handle="winterfell", user=user)
namespace2 = Namespace.objects.create(handle="thewall", user=user)

import django_namespaces

django_namespaces.activate("winterfell")

This will add a namespace to the request object.

def my_hello_world_view(request):
    print(request.namespace)  # <Namespace: winterfell>
    print(request.namespace.handle)  # winterfell
    return HttpResponse("Hello World")

from django.db import models
from django_namespaces.models import Namespace


class Location(models.Model):
    name = models.CharField(max_length=255, blank=True, null=True)
    namespace = models.ForeignKey(Namespace, on_delete=models.CASCADE)

Custom Namespace Model

If you want to use a custom namespace model, you can do so by setting the DJANGO_NAMESPACES_NAMESPACE_MODEL setting.

DJANGO_NAMESPACES_NAMESPACE_MODEL = "orgs.Organization"

Example model in orgs.models.py:

from django.db import models


class Organization(models.Model):
    handle = models.CharField(max_length=255, unique=True)

• handle is the only required field to swap the model.

Optional Views

Using views are optional. You can also use the activate function to activate a namespace.

Update URLconf

Update urls.py to include namespaces.urls:

urlpatterns = [
    # ...
    path("namespaces/", include("django_namespaces.urls")),
]

Create a namespace by visiting http://localhost:8000/namespaces/create/ and filling out the form.
