Various common Django-related routines.

Project description

This library consists of various Django-related routines that extend or modify the behaviour of the framework:

  • lots of abstract models to use
  • a user activity log app storing users’ IP addresses and user agents (useful for hunting down multi-accounts)
  • a simple score app
  • a tags app which is unlike other popular tagging applications for Django in the fact that it supports tagging by users and localized tags
  • extensions for settings.py (current directory resolution, namespace package support, settings profile support)
  • Choices: an enum implementation for Django forms and models (with predefined classes for languages, countries, etc.)
  • typical filters, template tags, models, form fields, etc.

Complete documentation for the package can be found here:

http://packages.python.org/lck.django/

The latest version can be installed via PyPI:

$ pip install lck.django

or:

$ easy_install lck.django

The source code repository and issue tracker are maintained on GitHub.

This package bundles some royalty free static images that are useful in almost every Django project:

For the curious, lck stands for LangaCore Kit. LangaCore is a one man software development shop of mine.

Note: lck.common requires Python 2.7 because all of its code is using the so-called four futures (absolute_imports, division, print_function and unicode_literals). One of the virtues in the creation of this library is to make the code beautiful. These switches give a useful transitional state between the old Python 2.x and the new Python 3.x. You should use them as well.

Note: Since 0.5.0 lck.django requires Django 1.3 because it makes my monkey-patching efforts much easier. Moreover, 1.3 nicely deprecates behaviour which I consider ugly.

Change Log

0.6.3

  • fixed an embarassing bug with the human-readable timediff filter

0.6.2

  • MACAddressField normalization bug fixed

0.6.1

  • buttonable Django admin with ModelAdmin
  • “Edit separately” links for ForeignKey fields supported in ModelAdmin
  • compressing PyLibMCCache backend in lck.django.cache_backends
  • backlinks support in activitylog
  • images crushed and optimized
  • use Pillow instead of PIL

0.6.0

Oh boy, lots of changes!

  • TimeTrackable just got a lot smarter. Includes cache_version attribute automatically updated on significant changes to the object. modified gets updated only when there are actual changes to the object. dirty_fields property shows changed attributes from last save (works also for objects composed from multiple models, including abstract ones).

    Inspired by David Cramer and Simon Willison at EuroPython 2011.

  • The dogpile-safe lck.django.cache now supports custom invalidators which enables invalidation not only by time but also by e.g. model changes (think TimeTrackable.cache_version).

  • Settings profile support now requires a modified manage.py script in the Django project. This is forced by the unfortunate design of how Django loads settings.

  • Activity logging moved to its own app, lck.activitylog, which now also tracks IPs and user agents of logged-in visitors (useful in hunting multi-accounts).

  • Introduced a SavePrioritized abstract model which adds priorities to saves on models. Various parts of the application can specify which priority they use. If they update an attribute which was first saved by something with higher priority, the update is silently ignored.

  • Introduced a concurrency-aware variant of the popular Model.objects.get_or_create (unsurprisingly called concurrent_get_or_create)

  • Introduced a commit_on_success variant that supports nesting (unsurprisingly called nested_commit_on_success)

  • Introduced BasicAuthMiddleware for simplistic private URL protecting.

  • EditorTrackable is now safe in terms of foreign key cascading (content authored or modified by a user won’t get deleted after this user is removed from the DB). Plus some nice admin refinements.

  • Now TimingMiddleware doesn’t break other middlewares using process_view() and is generally smarter.

  • Added X-Slo header in responses for TimingMiddleware.

  • render() now calculates and emits ETags based on the rendering output.

  • typical_handler() can now redirect_on_success.

  • Links from the BBCode filter now open in a new window and have rel="nofollow" set.

  • Introduced a {%settings KEY%} templatetag.

  • Introduced a {%git_version%} templatetag which returns a short string useful to present as an app version. This is based on the latest commit in the Git repository where the Django project lies in.

  • The cycle_filter template filter now supports explicit counter settings and incrementation.

  • Introduced template filters converting to and from Base64.

  • Introduced JQuery UI and JQueryMobile integrated radio widgets.

  • Improved documentation.

  • More complete translations.

0.5.8

  • Simplistic TimingMiddleware introduced.
  • Profiles based on BaseProfile now return self for get_profile().
  • Trophy icons added.
  • Console tag library introduced with the {%color%} tag.
  • Allow rendering non-request contexts.
  • Choices.ToNames decorator introduced.
  • Pre-importing in manage.py shell works also for models with a custom``app_model``.

0.5.7

  • EditorTrackable introduced
  • Choices can be rendered in grouped form. Currently requires adding '--keyword=Group:2 ' to xgettext invocations in django/core/managemenet/commands/makemessages.py. Cleaning that up is planned for 0.6.0.
  • typical_handler works now with forms w/o a save() method
  • upperfirst filter introduced: ups only the first character
  • Square thumbnails for wide images now work properly
  • moved contents of helpers to common (enables i18n and cleans up the API), the helpers module is therefore deprecated
  • some i18n updates

0.5.6

  • in the thumbnail filter, support for automatic cropping to square introduced
  • minor translation updates

0.5.5

  • group members inherit shifted attributes

0.5.4

  • minor updates to PolishDateWidget

0.5.3

  • AvatarSupport abstract model for custom avatars. GravatarSupport can be used as fallback or independently.
  • typical_handler now properly supports file uploads
  • bugfixes: objects without any score don’t cause exceptions anymore
  • leftovers from namespace changes cleaned up

0.5.2

  • monkey patches of core Django annotated and regrouped for easier management in the future (yup, more to come)
  • a stats calculator
  • minor bugfixes

0.5.1

  • tags now support models with custom managers
  • for Named and Titled models a read-only name_urlencoded and title_urlencoded properties were introduced. Useful as arguments in template tags.
  • support for setting additional attributes on choices using an unholy << operator overload
  • in tags, support for getting objects marked with specific stems

0.5.0

  • migrated to the lck namespace from langacore.kit
  • migrated licensing from GPL 3 to MIT
  • bumped the trove from alpha status to beta, the code is in production for over a year now

Ancient history

  • No proper change log was kept before 0.5.0
