Eventum is a content management system for an event-driven blog that syncs with Google Calendar.

1. First things first, make sure to install Eventum. To do so, use pip:

   pip install -U eventum

2. Install MongoDB (Ubuntu Linux, OSX).

   On OSX, you may have to run mkdir /data /data/db before you can run mongod without errors.

3. Install SASS gem

   gem install sass

   Otherwise, you will see an intermittent OSError

4. Authorize your application with Google.

   $ python -m eventum.authorize <CLIENT-SECRET-PATH> <CLIENT-CREDENTIALS-PATH>

5. Eventum needs to have several configuration variables set in the Flask config object in order to operate properly. These may be set as key/value pairs in a dictionary called EVENTUM_SETTINGS, or may be set individually with the prefix EVENTUM_.

   • INSTALLED_APP_CLIENT_SECRET_PATH: Path from the root of your project to the installed application client secret JSON file downloaded from Google.
   • INSTALLED_APP_CREDENTIALS_PATH: Path from the root of your project to the installed application credentials JSON file generated by the authorization in the previous step.
   • CLIENT_SECRETS_PATH: Path from the root of your project to the client secret JSON file
   • PRIVATE_CALENDAR_ID: The Google Calendar ID for the private calendar to which unpublished events should be synced.
   • PUBLIC_CALENDAR_ID: The Google Calendar ID for the public calendar to which published events should be synced.
   • UPLOAD_FOLDER: Path from the root of your project to the folder where uploaded images should be stored.
   • DELETE_FOLDER: Path from the root of your project to the folder where uploaded images that are then deleted should be stored.

   Here's an example of what that might look like:

   from flask import Flask
   app = Flask(__name__)
   app.config['EVENTUM_SETTINGS'] = {
       'INSTALLED_APP_CLIENT_SECRET_PATH': 'config/inst_client_secrets.json'
       'INSTALLED_APP_CREDENTIALS_PATH': 'config/inst_credentials.json'
       'CLIENT_SECRETS_PATH': 'config/oauth_client_secrets.json'
       'PRIVATE_CALENDAR_ID': '[email protected]'
       'PUBLIC_CALENDAR_ID': '[email protected]'
       'UPLOAD_FOLDER': 'app/static/img/uploaded'
       'DELETE_FOLDER': 'app/static/img/uploaded/deleted'
   }

6. Initialized the Eventum class, passing in your Flask app:

   from eventum import Eventum
   eventum = Eventum(app)

Eventum can be configured using Flask configuration settings. Configurations can be supplied in a group, by defining key/value pairs in a dictionary called EVENTUM_SETTINGS, or they can be provided individually with the prefix EVENTUM_. Here are all of the Eventum configuration options, with their defaults. Note that CSRF_ENABLED is a Flask configuration and MONGODB_SETTINGS is a Mongoengine configuration:

# We enable Flask CSRF for secure forms.
CSRF_ENABLED = True

# We default to using the MongoDB 'eventum' database in Mongoengine
MONGODB_SETTINGS = {'DB': 'eventum'}

# Path the default profile picture to use in Eventum
EVENTUM_DEFAULT_PROFILE_PICTURE = 'img/default_profile_picture.png'

# Path to the default event image
EVENTUM_DEFAULT_EVENT_IMAGE = 'img/default_event_image.jpg'

# Whether or not Google Auth should be enabled or not.  If it is not enabled,
# you will default to a super-user account that bypasses all Google auth.
EVENTUM_GOOGLE_AUTH_ENABLED = True

# The name of the application log 
EVENTUM_APP_LOG_NAME = 'app.log'

# The name of the Werkzeug log 
EVENTUM_WERKZEUG_LOG_NAME = 'werkzeug.log'

# The maximum size of the Eventum logs 
EVENTUM_LOG_FILE_MAX_SIZE = 256

# The URL at which the Eventum admin interface should be mounted.
EVENTUM_URL_PREFIX = '/admin'

# File extensions that are allowed to be uploaded via the Media tab.
EVENTUM_ALLOWED_UPLOAD_EXTENSIONS = set(['.png', '.jpg', '.jpeg', '.gif'])

# The Eventum base path. If you're not sure what this is, don't mess with it.
EVENTUM_BASEDIR = eventum.__path__[0]

# Eventum static folder
EVENTUM_STATIC_FOLDER = path.join(EVENTUM_BASEDIR, 'static/')

# Eventum  SCSS folder
EVENTUM_SCSS_FOLDER = path.join(EVENTUM_STATIC_FOLDER, 'eventum_scss/')

# Eventum templates folder
EVENTUM_TEMPLATE_FOLDER = path.join(EVENTUM_BASEDIR, 'templates/')

######################
# Must be overridden #
######################

# Path from the root of your project to the installed application client
# secret JSON file downloaded from Google.
EVENTUM_INSTALLED_APP_CLIENT_SECRET_PATH = None

# Path from the root of your project to the installed application credentials 
# JSON file generated by the authorization in the previous step.
EVENTUM_INSTALLED_APP_CREDENTIALS_PATH = None

# Path from the root of your project to the client secret JSON file 
EVENTUM_CLIENT_SECRETS_PATH = None

# The [Google Calendar ID][gcal-id] for the private calendar to which
# unpublished events should be synced.
EVENTUM_PRIVATE_CALENDAR_ID = None

# The [Google Calendar ID][gcal-id] for the public calendar to which published
# events should be synced.
EVENTUM_PUBLIC_CALENDAR_ID = None

# Path from the root of your project to the folder where uploaded images
# should be stored. 
EVENTUM_UPLOAD_FOLDER = None

# Path from the root of your project to the folder where uploaded images that
# are then deleted should be stored.
EVENTUM_DELETE_FOLDER = None

# Will be set elsewhere, do not set directly
EVENTUM_GOOGLE_CLIENT_ID = None

Here's how to run Eventum in a development environment:

mongod &
python setup.py devlelop

It is possible to run Eventum without logging in using Google+ or authenticating with Google Calendar. To do so, set the Flask configuration variable EVENTUM_GOOGLE_AUTH_ENABLED to FALSE:

# Whether or not to enable Google Auth or not.
echo $EVENTUM_GOOGLE_AUTH_ENABLED

Follow the Peter Down's tutorial to get setup, and then you can do several things:

Publish to PyPI Testing:

python setup.py sdist upload -r pypitest

Publish to PyPI Live:

python setup.py sdist upload -r pypi

• Built in Flask
• Flask-Mongoengine and Mongoengine are used to interface with MongoDB
• Authentication is done with Google+ server-side flow
• Forms and validation are done through Flask-WTForms and WTForms
• CSS is generated from SCSS and managed with Flask-Assets
