Blender Extensions

Blender Extensions platform, heavily inspired by Mozilla's https://github.com/mozilla/addons-server.

Requirements

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

Development

Extra requirements

• virtualenv

Setup

Checkout Blender Web Assets submodule first:

git submodule update --init --recursive

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

virtualenv .venv -p python
source .venv/bin/activate

Install required packages:

pip install -r requirements_dev.txt

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

Run development server

./manage.py runserver 8111

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

127.0.0.1	extensions.local

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://staging.extensions.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://staging.extensions.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.

Feature Flags

At the moment there are the following feature flags:

• is_alpha
• is_beta

To create them run

./manage.py waffle_switch --create is_alpha on

./manage.py waffle_switch --create is_beta off

They can optionally be setup on the deployment platform to set the release stage of the site. These settings will be removed once the site is officially launched.
