Contributing

Contributions are always welcome and appreciated! Here are some ways you can contribute.

Issues

You can and should open an issue for any of the following reasons:

you found a bug; steps for reproducing, or a pull request with a failing test case will be greatly appreciated
you wanted to do something but did not find a way to do it after reading the documentation
you believe the current way of doing something is more complicated or less elegant than it can be
a related feature that you want is missing from the package

Please always check for existing issues before opening a new issue.

Pull requests

You want to contribute some code? Great! Here are a few steps to get you started:

Fork the repository on GitHub
Clone your fork and create a branch for the code you want to add

Create a new virtualenv and install the package in development mode

$ python -m venv venv
$ source venv/bin/activate
(venv) $ python -m pip install -U pip setuptools
(venv) $ pip install -U -e '.[validation]'
(venv) $ pip install -U -r requirements/dev.txt

Make your changes and check them against the test project

(venv) $ cd testproj
(venv) $ python manage.py migrate
(venv) $ python manage.py runserver
(venv) $ firefox localhost:8000/swagger/

Update the tests if necessary

You can find them in the tests directory.

If your change modifies the expected schema output, you should regenerate the reference schema at tests/reference.yaml:
```
(venv) $ python testproj/manage.py generate_swagger tests/reference.yaml --overwrite --user admin --url http://test.local:8002/
```
After checking the git diff to verify that no unexpected changes appeared, you should commit the new reference.yaml together with your changes.

Run tests. The project is setup to use tox and pytest for testing

# install test dependencies
(venv) $ pip install -U -r requirements/test.txt
# run tests in the current environment, faster than tox
(venv) $ pytest -n auto --cov
# (optional) sort imports with isort and check flake8 linting
(venv) $ isort --apply
(venv) $ flake8 src/drf_yasg testproj tests setup.py
# (optional) run tests for other python versions in separate environments
(venv) $ tox

Update documentation

If the change modifies behavior or adds new features, you should update the documentation and README.rst accordingly. Documentation is written in reStructuredText and built using Sphinx. You can find the sources in the docs directory.

To build and check the docs, run
```
(venv) $ tox -e docs
```
Push your branch and submit a pull request to the master branch on GitHub

Incomplete/Work In Progress pull requests are encouraged, because they allow you to get feedback and help more easily.
Your code must pass all the required CI jobs before it is merged

As of now, this consists of running on the supported Python, Django, DRF version matrix (see README), and building the docs successfully.
