Blender Extensions

Free and open source add-ons and themes for Blender.

Requirements

• Python 3.10
• virtualenv
• libmagic: sudo apt-get install libmagic1 in Debian/Ubuntu, brew install libmagic on OSX.

Development

Setup

Create and activate a virtual environment using your favourite method, e.g.

python3.10 -m venv .venv
source .venv/bin/activate

Install required packages:

pip install -r requirements_dev.txt

Make a copy of example .env:

cp .env.example .env

Initialise submodules included into this repo:

git submodule update --init

Create the database tables and load some basic data to work with using the following commands:

./manage.py migrate
./manage.py loaddata **/fixtures/*.json

It's also possible to generate fake add-on data using the following command:

./manage.py generate_fake_data

Update /etc/hosts to point to extensions.local, e.g.:

127.0.0.1	extensions.local

Run development server

./manage.py runserver 8111

Now http://extensions.local:8111 should be ready to work with and it should be possible to log into http://extensions.local:8111/admin/ with admin/admin.

Blender ID

Blender Extensions, as all other Blender web services, uses Blender ID. Blender Extensions can also receive Blender ID account modifications such as badge updates via a webhook.

For development, Blender ID's code contains a fixture with an OAuth app and a webhook 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_extensions_devserver

N.B.: the webhook view delegates the actual updating of the user profile to a background task, so in order to see the updates locally, start the processing of tasks using the following:

./manage.py process_tasks

Blender ID and staging/production

For staging/production, create an OAuth2 application in Blender ID using Admin › Blender-ID › OAuth2 applications -> Add:

• Redirect URIs: https://extensions.staging.blender.org/oauth/authorized (https://extensions.blender.org for production);
• Client type: "Confidential";
• Authorization grant type: "Authorization code";
• Name: "Blender Extensions Staging" (or "Blender Extensions" for production);

Copy client ID and secret and save them as BID_OAUTH_CLIENT and BID_OAUTH_SECRET into a .env file:

export BID_OAUTH_CLIENT=<CLIENT ID HERE>
export BID_OAUTH_SECRET=<SECRET HERE>

Create a webhook using Admin › Blender-ID API › Webhooks > Add:

• Name: "Blender Extensions Staging" (or "Blender Extensions" for production)";
• URL: https://extensions.staging.blender.org/webhooks/user-modified/ (or https://extensions.blender.org/webhooks/user-modified/ for production);
• App: choose the app created in the previous step;

Copy webhook's secret into the .env file as BID_WEBHOOK_USER_MODIFIED_SECRET:

export BID_WEBHOOK_USER_MODIFIED_SECRET=<WEBHOOK SECRET HERE>

Pre-commit hooks

Make sure to enable pre-commit hooks after installing requirements from requirements_dev.txt:

pre-commit install

This will enable formatting pre-commit checks for Django templates, Python and JS modules.

Testing

To simply run the test suit use

./manage.py test

To run tests and generate a coverage report use

coverage run manage.py test && coverage html

and then open htmlcov/index.html with your favourite browser.

Deploy

See playbooks.
