This repository uses git-flow conventions; main contains the most recent release, and work in progress will be on the develop branch. Pull requests should be made against develop.
Initial setup and installation:
Recommended: create and activate a python 3.9 virtualenv:
virtualenv cdhweb -p python3.9 source cdhweb/bin/activate
Use pip to install required python dependencies. To install production dependencies only:
pip install -r requirements.txt
To install all development requirements:
pip install -r requirements/dev.txt
Install django-compressor dependencies:
Copy sample local settings and configure for your environment:
cp cdhweb/local_settings.py.sample cdhweb/local_settings.py
You must add a
SECRET_KEY value in your local settings.
- Download licensed fonts and install locally under /sitemedia/fonts/
- Install OpenCV dependencies (if necessary) for wagtail image feature detection
Setup pre-commit hooks
If you plan to contribute to this repository, please run the following command:
This will add a pre-commit hook to automatically style your python code with black.
Because these styling conventions were instituted after multiple releases of
development on this project,
git blame may not reflect the true author
of a given line. In order to see a more accurate
git blame execute the
git blame <FILE> --ignore-revs-file .git-blame-ignore-revs Or configure your git to always ignore styling revision commits: git config blame.ignoreRevsFile .git-blame-ignore-revs
Unit tests are written with py.test but use Django fixture loading and convenience testing methods when that makes things easier. To run them, first install test requirements (these are included in dev):
pip install -r requirements/test.txt
Run tests using py.test:
Visual regression tests are written using the Python bindings for Selenium, and DOM snapshots are uploaded to Percy. They run in CI on pushes or pull requests to the develop branch.
Before visual tests are run, the CI build will execute:
python manage.py create_test_site
Which uses existing pytest fixtures to populate the database with content approximating a real website in order to execute the tests. It will then run:
npm run test:visual
Which starts a Django development server and calls the ci/visual_tests.py script to upload DOM snapshots to Percy for regression analysis.
You can use both of these commands locally if you need to accomplish either of these tasks. You will need to have the dependencies in requirements/test.txt installed, and set PERCY_TOKEN in your shell environment.
Documentation is generated using sphinx To generate documentation, first install development requirements:
pip install -r requirements/dev.txt
Then build the documentation using the customized make file in the docs directory:
cd sphinx-docs make html
When building documentation for a production release, use make docs to update the published documentation on GitHub Pages.
On every commit, GitHub Actions will generate and then publish a database diagram to dbdocs @ princetoncdh/cdh-web. But to generate locally, install and log into dbdocs. Then run:
python manage.py dbml > cdhweb.dbml npx dbdocs build cdhweb.dbml --project cdhweb
