Django the Domain Driven Design way

This is a proof of concept to model django apps on a domain driven design way. The idea is to move Django app related stuff under infrastructure folder, so ideally an app folder structure would be:

app_folder/
    application/
    domain/
    infrastructure/
        migrations/
        admin.py
        models.py
        __init__.py
    __init__.py

Installation

To install from source, download the source code, then run this:

python setup.py install

Or install with pip

pip install django-ddd

Configuration

Select your desired app folder structure and add these settings to your project.

CUSTOM_MODELS_MODULE

Where Django should look for your app models.

Default: models

Example: infrastructure.models

CUSTOM_MIGRATIONS_MODULE

Where Django should look for your app migrations.

Default migrations

Example: infrastructure.migrations

CUSTOM_ADMIN_MODULE

Where Django should look for your app admin configuration.

Default admin

Example: infrastructure.admin

Usage

To use custom locations

Install django-ddd to your project requirements and add settings so Django can find your apps modules as seen on configuration. You don't need to add django-ddd to INSTALLED_APPS

Then, on your package apps.py import django-ddd custom app config:

from django_ddd.apps_config import CleanAppConfig

class AppNameConfig(CleanAppConfig):
    name = "app_name" # package folder name

Add your new application to INSTALLED_APPS

INSTALLED_APPS = [
    # ...
    "app_name.infrastructure.apps.AppNameConfig",
    # ...
]

This should be done explicitly after this ticket.

To use start_clean_app

This command creates a new Django app with a Domain Driven Design structure.

To use it, you need to add django-ddd to your INSTALLED_APPS:

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

Then, just call:

python manage.py start_clean_app app_name

This will create a new context with previously seen structure:

app_name/
    application/
    domain/
    infrastructure/
        migrations/
        admin.py
        models.py
        __init__.py
    __init__.py

Here all Django details are under infrastructure folder. Package level __init__.py has route to app config:

default_app_config = "app_name.infrastructure.apps.AppNaemAppConfig"

You can move this folder to your sources and add it to INSTALLED_APPS so Django can recognize it.

Contributing / Running project locally

Build the docker image:

docker build . -t django-ddd-dev

Run tests:

 docker run -v $(pwd)/.:/usr/src/app django-ddd-dev bash -c "pipenv run python manage.py test"
