Project description
Overview
django-simple-events lets you bind your models to events. This events have the following configuration options:
beginning
time
frecuency: single time, daily, weekly, montly, yearly
interval: times between frecuencies
repetitions
end
The event occurrences are stored in the DB when an event gets saved. If you don’t specify a maximum repetitions number or the end datetime, the event occurrences are updated periodically with the update_occurrences command.
Instalation
Add events to your INSTALLED_APPS:
INSTALLED_APPS = ( ... 'events', ... )
Set EVENTS_MAX_FUTURE_OCCURRENCES to indicate the maximum of future occurrences to recolect in the DB if an event is endless
EVENTS_MAX_FUTURE_OCCURRENCES = 50
You can also set EVENTS_MAX_PAST_OCCURRENCES
Usage
In the following examples we are going to relate Study objects to events.
Models
If you want to access from Study the events, it’s recommendable to add a generic relation
from django.db import models from django.contrib.contenttypes import generic from events.models import Event class Study(models.Model): ... events = generic.GenericRelation(Event) ...
API
Get the events related to a Study:
study = Study.objects.get(pk=1) study.events.all()
Add an event to a Study:
from events.models import Event from datetime import date, time study = Study.objects.get(pk=1) event = Event(date.today(), time.now()) event.related_object = study event.save() study.events.get(pk=event.pk)
Play with the occurrences of an event:
from events.models import Event event = Event.objects.get(pk=1) #get all the occurrences as an iter of datetimes event.get_occurrences() #get all of past occurrences as a list of datetimes event.get_past_occurrences() #get the last 20 past occurrences as a list of datetimes event.get_past_occurrences(20) #get the next 20 future occurrences as a list of datetimes event.get_future_occurrences(20) #update the Occurrence objects of an event event.update_occurrences(event.get_occurrences) #get the Occurrence objects of an event event.occurrence_set.all() #get all the Study objects that have occurrences in the future from datetime import datetime Study.objects.filter(events__occurrence__datetime__gt=datetime.now())
Admin
If, when you are editing a Study in admin, you want to also edit the related events, you are easilly done:
from django.contrib import admin from events.admin import EventInline class StudyAdmin(admin.ModelAdmin): ... inlines = EventInline, ... admin.site.register(Study, StudyAdmin)
Forms
You can also use the event form:
from events.forms import EventForm
