Wagtail pagetranslation

Allows to translate specific pages without replicating all wagtail pages tree structure.

Motivation

There are multiple approaches to localizing content on your Wagtail site. Solutions such as wagtail-localize rely on copying the entire page tree for each language, which can be inefficient. wagtail-modeltranslation requires a specific project structure and patches models on the fly, which can be risky. If all you need is to translate a few fields, this library is for you. Simply add TranslationMixin to the Page model, list the fields you want translated, and you're good to go.

Installation

python -m pip install wagtail-pagetranslation

How to use

Add "wagtail_pagetranslation" to list of applications after all wagtail apps

INSTALLED_APPS = [
    "your_wagtail_app_1",
    "your_wagtail_app_2",
    ...
    "wagtail_pagetranslation",
    ...
]

Set default language for wagtail_pagetranslation app

WAGTAIL_PAGETRANSLATION_DEFAULT_LANGUAGE = "en"

by default settings.LANGUAGES will be used

LANGUAGES = [
    ("en", "English"),
    ("nl", "Dutch"),
    ("uk", "Ukrainian")
]

or you can specify custom list

WAGTAIL_PAGETRANSLATION_LANGUAGES = [
    ("en", "English"),
    ("nl", "Dutch"),
    ("uk", "Ukrainian")
]

To make available translation per page type add TranslationMixin to your custom Page class. Note: mixin should be added before Page class.

from wagtail_pagetranslation.translation import TranslationMixin

class HomePage(TranslationMixin, Page):
    # list of fields that should have translation
    translatable_fields = ["title", ...]

By default URL for translated page is page url + ?lang=<lang_code> This can be change by overriding get_language method:

from wagtail_pagetranslation.translation import TranslationMixin as BaseTranslationMixin

class TranslationMixin(BaseTranslationMixin):
    # list of fields that should have translation
    translatable_fields = ["title", ...]

    def get_language(self, request):
        return request.GET.get("language")
