SECRET_KEY = ''

LTI_KEY = ''  # Consumer Key
LTI_SECRET = ''  # Shared Secret

LTI_TOOL_ID = ''  # A unique ID for the tool

SQLALCHEMY_DATABASE_URI = ''  # URI for database. (e.g. 'mysql://root:root@localhost/quiz_extensions')

GOOGLE_ANALYTICS = ''  # The Google Analytics ID to use.

REDIS_URL = ''  # URL for the redis server (e.g. 'redis://localhost:6379')

Create a virtual environment

virtualenv env

Run the server

flask run --with-threads

Ensure Redis is running. If not, start it with

redis-server --daemonize yes

Production Installation

This is for an Ubuntu 16.xx install but should work for other Debian/ubuntu based installs using Apache and mod_wsgi.

sudo apt-get update
sudo apt-get install libapache2-mod-wsgi python-dev apache2 python-setuptools python-pip python-virtualenv libxml2-dev libxslt1-dev zlib1g-dev

sudo a2enmod wsgi
sudo service apache2 restart

cd /var/www/

sudo git clone git@github.com:ucfopen/quiz-extensions.git

cd quiz-extensions/

sudo virtualenv env
source env/bin/activate

sudo env/bin/pip install -r requirements.txt

sudo nano /etc/apache2/sites-available/000-default.conf

Put this inside 000-default.conf after VirtualHost *:80 And before the ending </VirtualHost>:

#QUIZ EXTENSION CODE
Alias quiz-ext/static /var/www/quiz-extensions/static
<Directory /var/www/quiz-extensions/static>
    Require all granted
</Directory>

<Directory /var/www/quiz-extensions>
    <Files wsgi.py>
        Require all granted
    </Files>
</Directory>

WSGIDaemonProcess quiz-ext
WSGIProcessGroup quiz-ext
WSGIScriptAlias /quiz-ext /var/www/quiz-extensions/wsgi.py

Then:

sudo service apache2 reload

sudo cp config.py.template config.py

sudo nano config.py

Edit your config.py and change the variables to match your server:

DEBUG = False  # Leave False on production

API_URL = ''  # Canvas API URL (e.g. 'http://example.com/api/v1/')
API_KEY = ''  # Canvas API Key

# The default number of objects the Canvas API will return per page (usually 10)
DEFAULT_PER_PAGE = 10
# The maximum amount of objects the Canvas API will return per page (usually 100)
MAX_PER_PAGE = 100

# A secret key used by Flask for signing. KEEP THIS SECRET! (e.g. 'Ro0ibrkb4Z4bZmz1f5g1+/16K19GH/pa')
SECRET_KEY = ''

LTI_KEY = ''  # Consumer Key
LTI_SECRET = ''  # Shared Secret

LTI_TOOL_ID = ''  # A unique ID for the tool
LTI_DOMAIN = ''  # Domain hosting the LTI

SQLALCHEMY_DATABASE_URI = ''  # URI for database. (e.g. 'mysql://root:root@localhost/quiz_extensions')

Finally:

sudo service apache2 reload
