Blender Conference

Requirements

• Python 3.10
• virtualenv
• PostgreSQL

Recommended for local development:

• virtualenvwrapper

virtualenvwrapper adds commands for naming, creating, listing, activating and deactivating Python virtualenvs, which makes it much easier to work on various Python projects.

If you prefer not to use it, any other way of creating a virtualenv or venv will do.

Development quick start

• Checkout the main branch
• mkvirtualenv -a pwd blender-conference -p /usr/bin/python3.10
• pip install -r requirements_dev.txt
• git submodule update --init

Environment

We use python-dotenv to manage application settings. By default, the application can run locally without any configuration. For development (or production) overrides, create a .env file at the root of the repo that looks like:

# Development settings
DEBUG=True
CONN_MAX_AGE=600

Setup database

Blender Conference requires PostgreSQL set up and running.

If you have the createuser and createdb utilities:

createuser conference -P
createdb -O conference conference

Alternatively, to create a new Blender Conference database, run this as the PostgreSQL root user:

CREATE USER conference CREATEDB PASSWORD 'conference';
CREATE DATABASE conference OWNER conference;
\c conference
CREATE SCHEMA conference;
GRANT ALL ON schema conference TO conference;

In case of production, omit CREATEDB and make sure that both postgres and conference users have secure hard to guess passwords set. You can change the password using:

ALTER ROLE conference WITH PASSWORD 'new_password';

Create a DATABASE_URL value in the .env file that looks like:

DATABASE_URL=postgres://conference:conference@localhost:5432/conference

Load production snapshot (recommended) or start with an empty database

1. `docker exec --user postgres -i postgres psql conference < conference_prod_dump`
or
2. `manage.py migrate`

Create superuser

echo "from django.contrib.auth import get_user_model; User = get_user_model(); User.objects.create_superuser('admin', 'admin@blender.org', 'password')" | ./manage.py shell

Create system user

Conference uses a special system user to log various changes via admin LogEntry.

In order for this to work locally, SYSTEM_USER_ID must be set in the settings. The following will create a user and print out its ID, which you can then copy-paste into your settings.py:

echo "from django.contrib.auth import get_user_model; User = get_user_model(); print(User.objects.create_user('system', 'system@blender.org', 'password').id)" | ./manage.py shell

Start development server

Setup application to run on port 8009:

manage.py runserver 8009

Setup OAuth application in Blender ID

For development, Blender ID's code contains a fixture with an OAuth app that should work without any changes to default configuration. To load this fixture, go to your development Blender ID and run the following:

./manage.py loaddata blender_conference_devserver

Running tests

Tests can be run by issuing ./test.sh in the repository root directory.

Update BWA (assets_shared/)

For updating the base styling provided by Blender Web Assets, navigate to assets_shared/ and pull latest changes:

cd assets_shared/
git checkout master && git pull
cd ..

N.B.: because project's static assets depend on BWA SASS modules, and "compiling" those can fail due to, e.g., incorrect font paths or missing files, always check that collectstatic works before committing this kind of update:

./manage.py collectstatic  --noinput

After making sure everything looks as expected, commit the updated submodule reference:

git add assets_shared
# add and commit the rest of the changes

Panel setup

• The panel is available at /<edition>/panel

Deploy to production

In order to put commits in production, they need to be moved from the master branch into the production branch:

git checkout production && git merge --ff-only master

Use ./deploy.sh quick|full to deploy to production. If you added or updated a package, you must run full to update the base Docker image and ensure the presence of new or updated packages. Otherwise, quick simply collects the latest version of the code and assets.

Media and Static Files configuration

By default, we use Django's default static files configuration. However, in case of deployment to platforms that do not support serving static files, it is possible to configure S3 compatible storage for media, and enable WhiteNoise to serve static assets.

This can be done by adding declaring the following env variables:

AWS_STORAGE_BUCKET_NAME=''
AWS_S3_REGION_NAME=''
AWS_S3_ENDPOINT_URL=''
AWS_ACCESS_KEY_ID=''
AWS_SECRET_ACCESS_KEY=''

MEDIA_ROOT='media'
MEDIA_URL='${AWS_S3_ENDPOINT_URL}/'
STORAGE_DEFAULT='storages.backends.s3.S3Storage'

USE_WHITENOISE=True

Custom Looks

Use the HAS_OVERRIDES_APP=True setting to register an optional 'overrides' app which whill override templates and static (useful to fully customize the look of the website).
