The "local flavor" add-ons
|
|
==========================
|
|
|
|
Historically, Django has shipped with ``django.contrib.localflavor`` --
|
|
assorted pieces of code that are useful for particular countries or cultures.
|
|
This code is now distributed separately from Django, for easier maintenance
|
|
and to trim the size of Django's codebase.
|
|
|
|
The new localflavor package is named ``django-localflavor``, with a main
|
|
module called ``localflavor`` and many subpackages using an
|
|
`ISO 3166 country code`_. For example: ``localflavor.us`` is the
|
|
localflavor package for the U.S.A.
|
|
|
|
Most of these ``localflavor`` add-ons are country-specific fields for the
|
|
:doc:`forms </topics/forms/index>` framework -- for example, a
|
|
``USStateField`` that knows how to validate U.S. state abbreviations and a
|
|
``FISocialSecurityNumber`` that knows how to validate Finnish social security
|
|
numbers.
|
|
|
|
To use one of these localized components, just import the relevant subpackage.
|
|
For example, here's how you can create a form with a field representing a
|
|
French telephone number::
|
|
|
|
from django import forms
|
|
from localflavor.fr.forms import FRPhoneNumberField
|
|
|
|
class MyForm(forms.Form):
|
|
my_french_phone_no = FRPhoneNumberField()
|
|
|
|
For documentation on a given country's localflavor helpers, see its README
|
|
file.

|
Internationalization of localflavors
|
|
====================================
|
|
|
|
To activate translations for the ``localflavor`` application, you must include
|
|
the application's name in the :setting:`INSTALLED_APPS` setting, so the
|
|
internationalization system can find the catalog, as explained in
|
|
:ref:`how-django-discovers-translations`.

How to migrate
|
|
==============
|
|
|
|
If you've used the old ``django.contrib.localflavor`` package or one of the
|
|
temporary ``django-localflavor-*`` releases, follow these two easy steps to
|
|
update your code:
|
|
|
|
1. Install the third-party ``django-localflavor`` package from PyPI.
|
|
|
|
2. Change your app's import statements to reference the new package.
|
|
|
|
For example, change this::
|
|
|
|
from django.contrib.localflavor.fr.forms import FRPhoneNumberField
|
|
|
|
...to this::
|
|
|
|
from localflavor.fr.forms import FRPhoneNumberField
|
|
|
|
The code in the new package is the same (it was copied directly from Django),
|
|
so you don't have to worry about backwards compatibility in terms of
|
|
functionality. Only the imports have changed.
|
|
|
|

Deprecation policy
|
|
==================
|
|
|
|
In Django 1.5, importing from ``django.contrib.localflavor`` will result in a
|
|
``DeprecationWarning``. This means your code will still work, but you should
|
|
change it as soon as possible.
|
|
|
|
In Django 1.6, importing from ``django.contrib.localflavor`` will no longer
|
|
work.
