#UDJ

UDJ is a social music player. It allows many people to control a single music player democratically. Checkout the UDJ homepage for more information. This is the official UDJ server. For details on the API for interacting with this server checkout the UDJ-0.6 REST API. You can also checkout the source for any of our several clients:

• Desktop Client
• Android Client
• iOS Client
• Web Client
• Windows Phone Client

The udj server requires several python packages. They can be found in requirements.txt and installed with the command

pip install -r requirements.txt

It is suggested that before executing the above command you first setup a virtual environment in which to work. This will greatly help in preventing and conflicts you may have between any currently installed python packages and the ones required by UDJ. For more information about virtual environment, please visit the virtualenv homepage.

Also note that UDJ uses geodjango so you'll need to have a spatial database. For more information on setting up a spatial database and getting it working with geodjango, please view the geodjango documentation. We recommend setting up a PostGIS database, however UDJ should work in theory with other spatial databases supported by geodjango.

In order to run the test server, there are several key variables that you must provide to the settings.py file. This can easily be done by creating a file called settings_local.py. The settings.py file will load this file and use any variables put in it. A skeleton of what a typical settings_local.py looks like can be found in settings_local.skel. Once you have all your settings configured, you can populate your database with test data by executing

python manage.py loaddata udj/fixtures/test_fixture.json

This populates the database with dummy data and creates an admin user with the username admin and the password udj.

Once you have everything setup, you can run the server by running the following command:

python manage.py runserver

1. First install virtualenv, postgres, postgis, and python-dev.

sudo apt-get install python-virtualenv postgresql-9.1-postgis postgresql-server-dev-9.1 python-dev

2. Next clone the Server Repository. For example:

clone https://github.com/klnusbaum/UDJ-Server.git

3. Move into the server directory:

cd UDJ-Server

4. Create the Virtual Environment that we're going to user:

virtualenv --distribute venv

5. Activate the Virtual Environment:

source venv/bin/activate

6. Install the necessary python packages:

pip install -r requirements.txt
pip install psycopg2==2.4.5

7. Login as the postgres User:

sudo su - postgres

8. Setup PostGIS by running the following commands:

POSTGIS_SQL_PATH=`pg_config --sharedir`/contrib/postgis-1.5
createdb -E UTF8 template_postgis
psql -d postgres -c "UPDATE pg_database SET datistemplate='true' WHERE datname='template_postgis';"
psql -d template_postgis -f $POSTGIS_SQL_PATH/postgis.sql
psql -d template_postgis -f $POSTGIS_SQL_PATH/spatial_ref_sys.sql
psql -d template_postgis -c "GRANT ALL ON geometry_columns TO PUBLIC;"
psql -d template_postgis -c "GRANT ALL ON geography_columns TO PUBLIC;"
psql -d template_postgis -c "GRANT ALL ON spatial_ref_sys TO PUBLIC;"

9. Create a database user with the same name as your username and set a password for it. For example, if you were currently logged in as the user steve you'd run:

createuser --createdb steve
psql
alter user steve with password 'django';

10. Exit the postgres user

exit

11. Create the UDJ database from the postgis template:

createdb -T template_postgis UDJ

12. Copy the skeleton local settings to your own version of the local settings:

cd udjserver
cp settings_local.skel settings_local.py

13. Open up settings_local in your favorite text editor. You'll need to:

• Change the SECRET_KEY to any 50 random characters
• Set the database ENGINE to django.contrib.gis.db.backends.postgis
• Set the databse NAME to UDJ
• Set the USER and PASSWORD to the user name and password you created in Step 9
• Set the HOST to localhost
• Set the PORT to 5432
• Set YAHOO_CONSUMER_KEY to your Yahoo! BOSS API Consumer Key
• Set YAHOO_CONSUMER_SECRET to your Yahoo! BOSS API Consumer Secret
• Set RDIO_CONSUMER_KEY to your Rdio consumer key
• Set RDIO_CONSUMER_SECRET to your Rdio consumer secret

14. Sync the database:

./manage.py syncdb

15. Migrate the database:

./manage.py migrate UDJ

16. Finally, you can run the server with:

./manage.py runserver
