Wagtail Modeltranslation
========================
This app is built using core features of django-modeltranslation: https://github.com/deschler/django-modeltranslation
It's an alternative approach for i18n support on Wagtail CMS websites.
The wagtail-modeltranslation application is used to translate dynamic content of
existing Wagtail models to an arbitrary number of languages, without having to
change the original model classes. It uses a registration approach (comparable
to Django's admin app) to add translations to existing or new projects and is
fully integrated into the Wagtail admin UI.
The advantage of a registration approach is the ability to add translations to
models on a per-app basis. You can use the same app in different projects,
whether or not they use translations, and without touching the original
model class.

Features
========
- Add translations without changing existing models or views
- Translation fields are stored in the same table (no expensive joins)
- Supports inherited models (abstract and multi-table inheritance)
- Handle more than just text fields
- Wagtail admin integration
- Flexible fallbacks, auto-population and more!
- Default Page model fields has translatable fields by default
- StreamFields are now supported!
Caveats
=======
:code:`wagtail-modeltranslation` patches Wagtail's :code:`Page` model with translation fields
:code:`title_xx`, :code:`slug_xx`, :code:`seo_title_xx`, :code:`search_description_xx` and :code:`url_path_xx` where "xx" represents the language code for each translated language. This
is done without migrations through command :code:`sync_page_translation_fields`. Since :code:`Page` model belongs to
Wagtail it's within the realm of possibility that one day Wagtail may add a conflicting field to :code:`Page` thus interfering with :code:`wagtail-modeltranslation`.
Wagtail's :code:`slugurl` tag does not work across languages. :code:`wagtail-modeltranslation` provides a drop-in replacement named :code:`slugurl_trans` which by default takes the slug parameter in the default language.
Quick start
===========
1. Install :code:`wagtail-modeltranslation`::
pip install wagtail-modeltranslation
2. Add 'wagtail_modeltranslation' to your ``INSTALLED_APPS`` setting like this (before all apps that you want to translate)::
INSTALLED_APPS = (
...
'wagtail_modeltranslation',
'wagtail_modeltranslation.makemigrations',
'wagtail_modeltranslation.migrate',
)
3. Add 'django.middleware.locale.LocaleMiddleware' to ``MIDDLEWARE`` on your ``settings.py``::
MIDDLEWARE = (
...
'django.middleware.locale.LocaleMiddleware', # should be after SessionMiddleware and before CommonMiddleware
)
4. Enable i18n on ``settings.py``::
USE_I18N = True
5. Define available languages on ``settings.py``::
from django.utils.translation import gettext_lazy as _
LANGUAGES = (
('pt', _('Portuguese')),
('es', _('Spanish')),
('fr', _('French')),
)
6. Create ``translation.py`` inside the root folder of the app where the model you want to translate exists::
from .models import Foo
from modeltranslation.translator import TranslationOptions
from modeltranslation.decorators import register
@register(Foo)
class FooTR(TranslationOptions):
fields = (
'body',
)
7. Run :code:`python manage.py makemigrations` followed by :code:`python manage.py migrate` (repeat every time you add a new language or register a new model)
8. Run :code:`python manage.py sync_page_translation_fields` (repeat every time you add a new language)
9. If you're adding :code:`wagtail-modeltranslation` to an existing site run :code:`python manage.py update_translation_fields`

Upgrade considerations (v0.10.8)
================================
- Template tag ``change_lang`` now needs a second parameter, ``page``
Upgrade considerations (v0.8)
=============================
This version includes breaking changes as some key parts of the app have been re-written:
- The most important change is that ``Page`` is now patched with translation fields.
- ``WAGTAILMODELTRANSLATION_ORIGINAL_SLUG_LANGUAGE`` setting has been deprecated.
To upgrade to this version you need to:
- Replace the ``WagtailTranslationOptions`` with ``TranslationOptions`` in all translation.py files
- Run :code:`python manage.py sync_page_translation_fields` at least once to create ``Page``'s translation fields
- Replace any usages of Wagtail's ``{% slugurl ... %}`` for :code:`wagtail-modeltranslation`'s own ``{% slugurl_trans ... %}``
- While optional it's recommended to add ``'wagtail_modeltranslation.makemigrations'`` to your INSTALLED_APPS. This will override Django's ``makemigrations`` command to avoid creating spurious ``Page`` migrations.
Upgrade considerations (v0.6)
=============================
This version has some important changes as there was a refactoring to include django-modeltranslation as a dependency instead of
duplicating their code in our version. This allow us to focus on Wagtail admin integration features as django-modeltranslation is
very well mantained and is very quickly to fix problems with the latest Django versions. This way we also keep all the django-modeltranslation
features (if you want you can also customize django-admin, for example). We also provide a new class to create the translation options classes: **WagtailTranslationOptions**
Most of the changes are related to imports as they change from wagtail-modeltranslation to modeltranslation.
To upgrade to this version you need to:
- Replace the ``TranslationOptions`` with ``WagtailTranslationOptions`` in all translation.py files
- The import of the register decorator is now ``from modeltranslation.decorators import register``
- The import of translator is now ``from modeltranslation.translator import translator``
