This page documents an example of using the Extensible Calendar Pro API with Django as the back end.

The Back End

First, we will set up the back end.

Creating the App with Source Control

Start by making a new Django project and app.

$ django-admin.py startproject cse330calendar
$ cd cse330calendar
$ python manage.py startapp cal

Right now would be a good time to set up your IDE and source control. Create a new Komodo project in the "cse330calendar" directory, and set up a repo on the "cse330calendar" in SourceTree. Make frequent commits after each step of the process.

Initial Configuration

Go into settings.py and configure your database.

Enable the admin panel, which requires editing both settings.py and urls.py. Add the cal application to the admin panel by creating cal/admin.py with the following content:

from django.contrib import admin

# We will create these models in the next step
from cal.models import Cal, Event

admin.site.register(Cal)
admin.site.register(Event)

Finally, add "cal" to the INSTALLED_APPS list in settings.py.

Creating the Models

Set up the models required for the Extensible Calendar. We have already done this work for you. Copy the following code into your cal/models.py file.

from django.db import models

# Extensible wants two models: a "calendar" model and an "event" model.
# The "calendar" model represents a collection of events.  Note that the end
# application supports multiple calendars in the same view, with the events
# in each calendar having a different background color.
# 
# First we will define our calendar model, `Cal`, and then we will define
# our event model, `Event`.

class Cal(models.Model):
	# Title of the calendar
	title = models.CharField(max_length=50)

	# Text description of the calendar
	description = models.CharField(max_length=200)

	 # Color ID (1-32)
	color = models.IntegerField(default=1)

	# Boolean for whether the calendar is hidden by default
	hidden = models.BooleanField(default=False)

class Event(models.Model):
	# Declare a one-to-many relationship with Cal
	cal = models.ForeignKey(Cal)

	# Title of the event
	title = models.CharField(max_length=50)

	# DateTime of event start
	start = models.DateTimeField()

	# DateTime of event end
	end = models.DateTimeField()

	# Additional information that can be associated with an event:
	loc = models.CharField(max_length=50) # Location
	notes = models.CharField(max_length=200) # Notes
	url = models.CharField(max_length=100) # URL
	ad = models.BooleanField(default=False) # Is this an all-day event
	rem = models.CharField(max_length=200) # Reminder
