volunteer-planner.org

Volunteer Planner is a platform to schedule shifts of volunteers. Volunteers register at the platform and choose shifts. The admin of the website can easily add new organizations, places and shifts. The software has a location based hierarchy (country / region / area / city) and has a hierarchy of organizations (organizations, facilities, tasks and workplaces) - it can be used for a variety of purposes.

Status

The project is currently running at https://volunteer-planner.org/.

Work in progress

There are some feature requests to be implemented in the future. The software currently needs a centralized administration of the shifts, but it is one of the main goals of the current development to empower organizations to schedule shifts for their facilities on their own.

If you are interested to join the development team, just make pull requests or come to a meeting in Berlin/Germany: http://www.meetup.com/de/coders4help/

System context

User: The volunteers and administrators just need a (modern) web browser to use the volunteer-planner application.

Developer: Developers need a python development environment (see project setup) and specific versions of external libraries (see /requirements directory, t). Development can be done with a sqlite databases, there is no need to run and configure postgres or mysql.

Server: For production use you need a Python ready web server, for example uWSGI as web server for the Python WSGI with nginx as proxy server visible to the end user (volunteers and administrators). You also need a MySQL or PostgreSQL database.

Project setup for development

0. Prerequisites (Ubuntu 14.04 example)

If your machine is setup to work on Django projects, you might skip this step.

0.1 Installing required OS packages

sudo apt-get install python-dev python-pip git npm

This will install Python libraries and Git.

0.2 Using MySQL locally (optional)

Using MySQL locally for development is optional.

0.2.1 Installing MySQL (optional)

If you are going to use a local MySQL server, additionally install

sudo apt-get install libmysqlclient-dev mysql-client mysql-server

This will install MySQL server, it will ask you to set a root password [ROOT_PASSWORD] for the MySQL server, if you haven't already set up MySQL in the past. Remember the password.

0.2.2 Creating a local MySQL database and user (optional)

Open the MySQL shell

mysql -u root -p

and execute following queries to setup the DB

CREATE DATABASE volunteer_planner;
GRANT ALL PRIVILEGES ON volunteer_planner.* to vp identified by 'volunteer_planner';

Note: For the local environment, the DB username is assumed to be 'vp' and their password is assumed to be 'volunteer_planner'.

1. Fork us on GitHub

Please fork us on GitHub and clone your fork

git clone https://github.com/YOUR_GITHUB_ACCOUNT/volunteer_planner.git

1.1 Creating Pull Requests

Please do Pull Requests against the develop branch.

If you have questions concerning our workflow please read the Development Rules wiki page.

2. Setup your virtual environment

2.1. Create a virtual env

Create an virtualenv (follow the installation guide at virtualenvwrapper to install virtualenvwrapper):

$ mkvirtualenv vp

Note: using vp as your virtualenv's name is a recommendation, not a requirement.

The virtual environment should be enabled afterwards. For starting/continuing working on the project using the virtualenv, activate the virtual env using

$ workon vp

2.2 Installing required python packages

Update pip

pip install -U pip

For a local sqlite DB install

pip install -r /path/to/volunteer_planner.git/requirements/dev.txt

or, if you intend to use MySQL locally, install

pip install -r /path/to/volunteer_planner.git/requirements/dev_mysql.txt

Note: /path/to/volunteer_planner.git means the path of your local clone of the GitHub project. Replace it accordingly with the actual path.

2.3 Setup your virtualenv `postactivate` hook (optional)

This step is optional but recommended.

Every time, a virtualenv is activated with virtualenvwrappers' workon command, a postactivate script is executed. This comes in handy to autmatically setup a projects' environment variables and automate some reoccuring tasks. For more details on virtualenvwrapper hooks, see virtualenvwrapper: Per-User Customization.

You might consider to use this example postactivate script (located at $VIRTUAL_ENV/bin/postactivate)

#!/bin/bash
# This hook is run after this virtualenv is activated.

export DJANGO_SETTINGS_MODULE="volunteer_planner.settings.local"
cd /path/to/volunteer_planner.git/

git fetch --all
git status

Note: You'll need to re-active your virtual environment after each change to it's postactivate hook to take effect. Just run workon vp again, to make sure your current venv session has executed the postactivate hook.

2.3.1 ... settings module for using MySQL

When you prefer to use MySQL locally, you'll probably need to use the settings module volunteer_planner.settings.local_mysql instead of volunteer_planner.settings.local.

2.3.2 Setup your local environment (optional)

Also, if you need to use non-default settings values, setting (exporting) the environment variables in your virtualenvs' postactivate hook is a good place if you're not using an IDE to configure your environment variables.

3. Initialize the database with Django

Activate your env and change dir to your local forks' git repository (if not done yet).

workon vp
cd /path/to/volunteer_planner.git

3.1 Run migrate management command to setup non-existing tables

./manage.py migrate

3.2 Add a superuser

./manage.py createsuperuser

You will be asked for username, email and password (twice). Remember that username and password.

4. Try running the server

./manage.py runserver

Try opening http://localhost:8000/ in your browser.

5. Adding content

To add new organizations and shifts, you have to access the backend at http://localhost:8000/admin. If prompted, login with the username/password of the superuser you created earlier (in case you don't see an error page here).

http://localhost:8000/admin

The Project

Create Dummy Data

Run management command

./manage.py create_dummy_data 5 --flush True

with activated virtualenv to get 5 days of dummy data and delete tables in advance.

The number (5 in the above example) creates 5 days dummy data count from today. If you just use ./manage.py create_dummy_data 5 without --flush it is NOT deleting data before putting new data in.

Running Tests

Feature pull requests should be accompanied by appropriate tests. We have unit and integration tests that are run with py.test, and functional/behave tests that are run with selenium.

To run unit tests, run the following command (with your virtual env activated, see 3.)

$ py.test -v [/path/to/volunteer_planner.git/]

If you want to generate a coverage report as well, run

$ py.test --cov=. --cov-report html --cov-report term-missing --no-cov-on-fail -v

This generates a nice HTML coverage page, to poke around which can be found at /path/to/volunteer_planner.git/htmlcov/index.html.

Note: The directory htmlcov is git-ignored.

To run selenium tests, run

$ behave tests/_behave

Translations

We use Transifex (tx) for managing translations.

General notes

Please read
- Django 1.8: Internationalization and localization
- Django 1.8: Translations
Please avoid internationalized strings / messages containing HTML markup. This makes the site layout depending on the translators and them getting the markup right; it's error prone and hardly maintainable when the page's layout changes.
use trimmed option in blocktrans template tags, if indention is not intended.
Please provide contextual markers on strings to help translators understanding the usage of the strings better. The shorter an internationalized string is, the more abigious it will be and the more important an contextual hint will be.

Workflow

Code your stuff using the ugettext_lazy as _ etc. methods to mark internationalized strings
Update the po files ./manage.py makemessages --no-wrap --no-obsolete -l en The options are intended to make the output more git-friendly.
Push the updated translations to git. Do not intend to translate in the local .po files, any changes here will be overwritten when translations are pulled from tx.
Transifex will automatically update the source strings via github once a day and make them available for translation. 4.1. If necessary, translation managers (meaning VP's Transifex project admins) can update the source language manually using the tx client command tx push -s django.
Translators will then translate on VP's Transifex project
When new translations are available on Transifex tx pull will update the local .po files with translations from TX
./manage.py makemessages --no-wrap --no-obsolete will reformat po files in a more readable single-line message string format
./manage.py compilemessages
Test if it looks good and works as intended
Commit and push the updated translations to git

Your local installation should be translated then. The .mo file created by compilemessages is gitignored, you'll need to (re-)generate it locally every time the .po file changes.

How to use the Transifex client

You first need to make sure that the transiflex client is installed (should be in the requirements/dev.txt file).

pip install transifex-client

For further installation infos and setup read Transifex: Client setup
Then, sign up at https://www.transifex.com, search for the project volunteer-planner.org, and join the respective team.
If you used an Oauth-ish method (Google, Facebook, etc.) to sign up for Transifex, you might need to set a password in your Transifex profile before you can use the client.
Edit your personal transifex configuration file that is stored in your home directory at ~/.transifexrc

[https://www.transifex.com]
username = YOUR_TRANSIFEX_USERNAME
token =
password = YOUR_TRANSIFEX_PASSWORD
hostname = https://www.transifex.com

Make sure not to share this file with anyone, as it contains your credentials! For more information on configuration, see http://docs.transifex.com/client/config/
