Project setup

Docker Compose

It's strongly recommended to follow the g3w-suite-docker installation instructions (which already bundles a full blown NGINX + PostgreSQL setup), as such installation method speed up development and deployment and would cause you fewer issues in terms of compatibility and portability in the short and long term.

Barebone server

If you will opt for the raw installation you will need to configure your own web server in order to run a Django project, some common setups are:

• Apache + mod_wsgi
• Apache + mod_proxy + Uwsgi
• Apache + mod_proxy + Gunicorn
• Nginx + Uwsgi
• Nginx + Gunicorn

To figure out which to choose, see also: deploying django

Then in your development environment:

1. download and install Node.js and Yarn
2. get a Python version that is compatible with the table above
3. install and activate a database that fits your needs
4. (optional) install Paver for developing locally

After that you can clone this repository:

cd /path/to/your/development/workspace

git clone https://github.com/g3w-suite/g3w-admin.git --single-branch --branch dev ./g3w-admin

Create and activate virtualenv within your g3w-admin local repository:

cd ./g3w-admin

python3 -m venv --system-site-packages [--prompt g3w-admin] venv

# Linux / Mac OS
source venv/bin/activate

# Windows
.\venv\Scripts\activate

Create the following configuration file from the available template:

• /g3w-admin/g3w-admin/base/settings/local_settings.py ← local_settings_example.py

And check that the following parameters are set accordingly:

# /g3w-admin/g3w-admin/base/settings/local_settings.py

DATASOURCE_PATH     = '<static_path_to_gis_data_source>'
MEDIA_ROOT          = '<path_to_media_root>'
SESSION_COOKIE_NAME = '<unique_session_id>'
DATABASES           = {
    'default': {
        'ENGINE': 'django.contrib.gis.db.backends.postgis',
        'NAME': '<db_name>',
        'USER': '<db_user>',
        'PASSWORD': '<db_user_password>',
        'HOST': '<db_host>',
        'PORT': '<db_port>',
    }
}

Complete installation process by download all python and javascript dependencies and finalizing the django database setup:

paver install

If you don't want to use Paver, see also: manual installation steps

How to develop

You can start the built-in development server by using the following:

paver start

paver stop

If everything went fine, you can now visit your local development server URL to see changes:

http://localhost:8000

If you don't want to use Paver, see also: run g3w-suite
