django-recurrence is a utility for working with recurring dates in Django.

Functionality

• Recurrence/Rule objects using a subset of rfc2445 (wraps dateutil.rrule) for specifying recurring date/times,
• RecurrenceField for storing recurring datetimes in the database, and
• JavaScript widget.

RecurrenceField provides a Django model field which serializes recurrence information for storage in the database.

For example - say you were storing information about a university course in your app. You could use a model like this:

.. code:: python

import recurrence.fields

class Course(models.Model): title = models.CharField(max_length=200) start = models.TimeField() end = models.TimeField() recurrences = recurrence.fields.RecurrenceField()

You’ll notice that I’m storing my own start and end time. The recurrence field only deals with recurrences not with specific time information. I have an event that starts at 2pm. Its recurrences would be “every Friday”.

Contributions

All contributions are welcome!

It is best to separate proposed changes and PRs into small, distinct patches by type so that they can be merged faster into upstream and released quicker.

One way to organize contributions would be to separate PRs for e.g.

• bugfixes,
• new features,
• code and design improvements,
• documentation improvements, or
• tooling and CI improvements.

Merging contributions requires passing the checks configured with the CI. This includes running tests and linters successfully on the currently officially supported Python and Django versions.

The test automation is run automatically with GitHub Actions, but you can run it locally with the tox command before pushing commits.

1.8.1

• Bad release, do not use.

1.8.0

This release contains two backwards incompatible changes - please read the notes below for details.

• django-recurrence now returns timezone aware datetime objects in most cases #130. If USE_TZ is True (it defaults to off with a stock Django install) then you'll now get timezone aware datetime objects back from django-recurrence. If you have USE_TZ as True, and you don't want this behaviour, you can set RECURRENCE_USE_TZ to False, but please let us know (via GitHub issues) that you wanted to opt out, so we can understand what your use case is.
• RecurrenceField instances without required=False will now require at least one rule or date. This change is intended to bring django-recurrence into line with how custom fields should behave. If you don't want to require at least one rule or date, just set require=False on your field #133.
• Improvements to avoid inline styles #85;
• Handle changes to javascript_catalog in Django 2 #131.

• Django 2.0 compatibility fix for usage of django-recurrence with Django REST framework #126.

1.6.0

• Fixes for Python 3 #105;
• Support for Django 2.0 #109, #110;
• Switch back a couple of instances of DeserializationError to ValidationError #111;
• Switch around how we set dates in the date selector widget to avoid issues with short months #113.

• Add minor style changes to make django-recurrence compatible with Wagtail #100;
• Allow changing the behaviour of generating recurrences on dtstart by default. You can opt in to this by setting include_dtstart=False on your RecurrenceField #93;
• Ensure broken values raise DeserializationError where expected #103.

• Fixed an off-by-one bug in the to_text method for events happening on a regular month each year #30;
• Fixed a bug in the JavaScript widget where the date for monthly events on a fixed date of the month had the description rendered incorrectly if the day selected was more than the number of days in the current calendar month #31;
• Added a French translation #32 - this may be backwards incompatible if have overriden the widget JavaScript such that there is no language_code member of your recurrence object;
• Added a Spanish translation #49;
• Added database migrations - running python manage.py migrate recurrence --fake should be sufficient for this version - nothing has changed about the database schema between 1.1.0 and 1.2.0;
• Fix broken tests for Django 1.4.
