Django web application for Princeton Prosody Archive version 3.x.
Code and architecture documentation for the current release available at https://princeton-cdh.github.io/ppa-django/.
This repo 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.
Python 3.9 / Django 4.0 / Node 16.15 / Postgresql 13 / Solr 8
Development instructions¶
Initial setup and installation:
recommended: create and activate a python 3.6 virtual environment, perhaps with
virtualenvorvenvUse pip to install required python dependencies:
pip install -r requirements.txt pip install -r dev-requirements.txt
Copy sample local settings and configure for your environment:
cp ppa/local_settings.py.sample ppa/local_settings.py
Create a database, configure in local settings in the DATABASES dictionary, change SECRET_KEY, and run migrations:
python manage.py migrate
Create a new Solr configset from the files in
solr_confcp -r solr_conf /path/to/solr/server/solr/configsets/ppa chown solr:solr -R /path/to/solr/server/solr/configsets/ppa
and configure SOLR_CONNECTIONS in local settings with your preferred core/collection name and the configset name you created.
See developer notes for setup instructions for using docker with solr:8.4 image.
Bulk import (provisional): requires a local copy of HathiTrust data as pairtree provided by rsync. Configure the path in localsettings.py and then run:
python manage.py hathi_import
Then index the imported content into Solr:
python manage.py index -i work python manage.py index_pages
Frontend development setup:
This project uses the Fomantic UI library in addition to custom styles and javascript. You need to compile static assets before running the server.
To build all styles and js for production, including fomantic UI:
npm install npm run build
Alternatively, you can rebuild just the custom files or fomantic independently. This is useful if you make small changes and need to recompile once:
npm run build:qa # just the custom files, with sourcemaps
npm run build:prod # just the custom files, no sourcemaps
npm run build:semantic # just fomantic UI
Finally, you can run a development server with hot reload if you’ll be changing either set of assets frequently. These two processes are separate as well:
npm run dev # serve just the custom files from memory, with hot reload
npm run dev:semantic # serve just fomantic UI files and recompile on changes
If running this application on MariaDB/MySQL, you must make sure that time zone definitions are installed. On most flavors of Linux/MacOS, you may use the following command, which will prompt for the database server’s root password:
mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root mysql -p
If this command does not work, make sure you have the command line utilities for MariaDB/MySQL installed and consult the documentation for your OS for timezone info. Windows users will need to install a copy of the zoneinfo files.
See MariaDB’s info on the utility for more information.
Tests¶
Python 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 development requirements:
pip install -r dev-requirements.txt
Run tests using py.test. Note that this currently requires the top level project directory be included in your python path. You can accomplish this either by calling pytest via python:
python -m pytest
Or, if you wish to use the pytest command directly, simply add the
top-level project directory to your python path environment variable:
setenv PYTHONPATH . # csh
export PYTHONPATH=. # bash
Make sure you configure a test solr connection and set up an empty Solr core using the same instructions as for the development core.
Note that python unit tests access a test server over HTTP, and therefore expect static files to be compiled – see “Frontend development setup” above for how to do this.
In a CI context, we instead use a webpack-stats.json file that mocks the
existence of the static files so they aren’t required. This file is located in
the ci/ directory and needs to be updated if new entrypoints are configured
in webpack.config.js.
Javascript unit tests are written with Jasmine
and run using Karma. To run
them, you can use an npm command:
npm test
Automated accessibility testing is also possible using pa11y
and pa11y-ci. To run accessibility tests,
start the server with python manage.py runserver and then use npm:
npm run pa11y
The accessibility tests are configured to read options from the .pa11yci.json
file and look for a sitemap at localhost:8000/sitemap.xml to use to crawl the
site. Additional URLs to test can be added to the urls property of the
.pa11yci.json file.
Setup pre-commit hooks¶
If you plan to contribute to this repository, please run the following command:
pre-commit install
This will add a pre-commit hook to automatically style and clean python code with black and ruff.
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 following command:
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
Documentation¶
Documentation is generated using sphinx To generate documentation them, first install development requirements:
pip install -r dev-requirements.txt
Then build documentation using the customized make file in the docs
directory:
cd sphinx-docs
make html
To check documentation coverage, run:
make html -b coverage
This will create a file under _build/coverage/python.txt listing any
python classes or methods that are not documented. Note that sphinx can only
report on code coverage for files that are included in the documentation. If a
new python file is created but not included in the sphinx documentation, it
will be omitted.
Documentation will be built and published with GitHub Pages by a GitHub Actions
workflow triggered on push to main.
The same GitHub Actions workflow will build documentation and checked documentation coverage on pull requests.
