Django Girls website

Build Status codecov

This repository contains the Django application which powers DjangoGirls.org.

What's in it?

It's a simple CMS that contains 3 main models:

How to create new event?

Simply go to command line and run this command:

python ./manage.py new_event

And then follow the instructions.

How to manage your website?

Event

http://djangogirls.org/admin/core/event/

Here you can change:

EventPageContent

http://djangogirls.org/admin/core/eventpagecontent/

Each website comes with some default content that you can adjust to your needs. Each object is a "block" on the website that you can modify in following ways:

EventPageMenu

http://djangogirls.org/admin/core/eventpagemenu/add/

To manage menu available on the website, you can add objects to EventPageMenu. Available options:

Contributing to Django Girls website

The website is hosted on PythonAnywhere and is available here: http://djangogirls.org/

Please note that we use Python 3 only, so make sure that you use correct version when running commands below.

Setting up a development environment

First, fork and clone the repository:

git clone git@github.com:your-username/djangogirls.git

Step into newly created djangogirls directory:

cd djangogirls

Docker

If you have Docker and Docker compose installed, run docker-compose up

Non Docker

Create a new virtual environment (Python 3.10) if needed. Then, install all the required dependencies.

The dependencies are compiled by pip-tools, which compiles requirements.txt ensuring compatibility between packages.

pip install pip-tools
pip-sync

There is more information on how pip-tools work below in Using pip-tools.

Install the pre-commit hook. It's useful so we automatically format and lint code before committing any changes.

pre-commit install

Start the PostgreSQL database server and enter the psql shell (you need to have PostgreSQL installed):

psql

In the psql shell, create a database and a role with the necessary permissions:

CREATE DATABASE djangogirls;
CREATE ROLE postgres;
GRANT ALL privileges ON DATABASE djangogirls TO postgres;
ALTER ROLE postgres WITH LOGIN;

Exit the psql shell:

\q

Run the migration to create database schema:

./manage.py migrate

Load sample data to the database

./manage.py loaddata sample_db.json

Create a user so you can login to the admin:

./manage.py createsuperuser

Install dependencies for static files:

npm install

Compile CSS and JS files:

gulp watch

Run your local server:

./manage.py runserver

:tada: You're done.

Run the tests

You can run the tests like this:

python -m pytest

Or if you want coverage reports:

python -m pytest --cov

For a coverage report with information about missing lines, run this:

python -m pytest --cov-report term-missing --cov

Static files

We're using a Stylus as our CSS pre-processor. Get styling with Stylus.

This means you shouldn't change any css files, but .styl files. They're in /static/source/css/ directory.

Autocompiling of .styl files to .css:

npx gulp watch

We're also using gulp for our static files builds (see below). To build static files for production, run this:

npx gulp build

For local development:

npx gulp local

Gulp Tasks

Static files are generated and maintained using gulp.js. To use, you'll need Node.js installed. Then, run npm install. You can now use npx gulp (note that it's np**x**), followed by one of the following commands:

Running gulp on its own runs watch by default.

Developing Gulp Tasks

Each gulp task is a single function, which are combined using the series operator so they run as a workflow. Each are commented with what they do and why they're important.

The biggest gotcha is async completion. Each task much signal to gulp when it has finished. The easiest way to do this is using an aysnc function, but if your functionality uses gulp streams (most native gulp functionality does), then you should not use an async function. Instead, return the gulp stream from the function and it will be handled correctly.

// WRONG - uses gulp's streams in an async function; subsequent tasks won't wait for completion correctly:
const copyFiles = async () => {
    return gulp.src(...).pipe(gulp.dest(...))
}

// RIGHT - either returns a gulp stream _or_ uses an `async` function:
const copyFiles = () => {
    return gulp.src(...).pipe(gulp.dest(...))
}
const deleteFiles = async () => {
    await del(...)
}

Hosting on PythonAnywhere

Key bits of config and secrets are stored in environment variables in two places:

Google Apps API integration

We're using Google Apps Admin SDK for creating email accounts in djangogirls.org domain automatically.

Several things were needed to get this working:

  1. Create an app in Developer Console
  2. Create a service account to enable 2 legged oauth (https://developers.google.com/identity/protocols/OAuth2ServiceAccount)
  3. Enable delegation of domain-wide authority for the service account.
  4. Enable Admin SDK for the domain.
  5. Give the service account permission to access admin.directory.users service (https://admin.google.com/AdminHome?chromeless=1#OGX:ManageOauthClients).

Using pip-tools

The packages required by the project are in requirements.in which looks like a regular requirements file. Specific versions of packages can be specified, or left without a version in which case the latest version which is compatible with the other packages will be used.

If you are working on a feature which requires a new package, add it to requirements.in, specifying a version if necessary. It's dependencies will be included in requirements.txt by the compile process.

The only time a dependency of a third party package needs adding to requirements.in is when a version has to be pinned.

By running pip-compile the requirements are compiled into requirements.txt.

Periodically requirements should be updated to ensure that new versions, most importantly security patches, are used. This is done using the -U flag.

Once requirements are compiled, pip-sync will install the requirements, but also remove any packages not required. This helps to ensure you have the packages required, but also that there isn't something installed that's missed from requirements.txt.

For example:

pip-compile -U
pip-sync

Handling environment variables

The requirements.txt installs python-dotenv which provides the option for developers to load environment variables via a single file.

You'll see .environment-example in the project root. This contains environment variables used by the project so that you can create your own copy of this and load it with values relevant to your development environment.

To make use of this feature, create a copy of the example file and call it .environment. This file will be ignored by version control, but loaded by manage.py. So when you run django commands like manage.py runserver during development python-dotenv will load the environment variables from your .environment file so that they are available to the application.

This is an optional feature. If you do not have a .environment file then it won't impact on the application at all.

Before you Open a Pull Request

This project runs a linting check with flake8 whenever a pull request is merged. Before you create a pull request, it's advisable to fix any linting issues locally to avoid errors while merging. In order to have flake8 run in your local machine automatically you can do the following:

1) Run pip install pre-commit to install pre-commit. This package helps setting up git hooks.

2) Run pre-commit install to install the git hook. After this, whenever you run git commit in your local machine, flake8 will run and report any linting errors that it found.

3) If you've already committed your changes before installing pre-commit, you can follow steps 1 and 2 and then run pre-commit run --all-files to run flake8 against all of the files.
