Merou is an application to allow users to create and manage memberships to their own groups.

Note: We recently renamed the project to avoid a namespace conflict, but it isn't reflected in the codebase yet.

Standard Python package installation instructions apply. You will need development headers for MySQL and Python 2 available.

On Debian-based systems:

apt-get install libmysqlclient-dev libpython2.7-dev
pip install -e git+https://github.com/dropbox/merou#egg=grouper

Next you need to configure grouper to find a SQL-style backing database and stand up processes to serve the read-write web UI and read-only programmatic API. There's an sample configuration file, suitable for local development and testing, in config/dev.yaml.

Grouper runs behind a reverse proxy that handles authentication and so expects a valid, authenticated, user account. I've included a test proxy for running on development instances.

Creating a development instance:

export PYTHONPATH=$(pwd)
export GROUPER_SETTINGS=$(pwd)/config/dev.yaml

# Setup the database.
bin/grouper-ctl sync_db

## You can either run all the various servers and the reverse-proxy
## via a helper script:
tools/run-dev --user $USER@example.com

## Or separately:
# Run the development reverse proxy
bin/grouper-ctl -vv user_proxy $USER@example.com

# Run the frontend server
bin/grouper-fe -vv

# Run the graph/api server
bin/grouper-api -vv

In order to bootstrap your new Grouper environment, you will want to create a user for yourself and add it to the grouper-administrators group.

export PYTHONPATH=$(pwd)
export GROUPER_SETTINGS=$(pwd)/config/dev.yaml

bin/grouper-ctl -vv\
    user create $USER@example.com

# Give the user administrative access to the Grouper instance
bin/grouper-ctl -vv \
    group add_member --owner grouper-administrators $USER@example.com

Some tests require a recent (>= 2.31) version of chromedriver, which can be installed via apt or Homebrew:

apt install chromium-chromedriver

Once chromedriver is installed, the tests can be run using pytest:

pip install -r requirements.txt
pip install -r requirements-dev.txt
py.test tests
