Wagtail Parler 🧀 🐦

Brings "omelette du fromage" 🧀 from parler into wagtail 🐦 for your custom models (via modeladmin or wagtail snippets)

Wagtail Parler helps you to use django-parler inside wagtail to translate your customs models. It works for wagtail-modeladmin (which is now deprectaed) and also the new official way: wagtail's snippets.

Tests, QA, consistency and compatibility

This app is tested to runs with:

• Django 4.2, 5.0, 5.2
• Wagtail 5.0, 5.1, 5.2, 6.0, 6.1, 6.2, 7.0
• Parler 2.3 (probably older ones to, it's just not tested)
• Python 3.9, 3.11

To ensure code quality and consistency:

• Formatted with black
• Validated with flake8.
• Static types checked with mypy
• Tests coverage checked with coverage (100% tested)
• Tests runned in local via tox and on github via github actions workflow
• versionned with semver logic

Why

There is already an internationalisation support in wagtail via their own language features called wagtail-localize. This app also support wagtail modeladmin. But the approach of wagtail-localize could be unconvenient as translations are stored in the same table than "main instances", resulting specific queryset and managers to manage your models.
For app's like treebeard, it can break the logic of your tree.

For those reasons, you could prefer to use django-parler as translations approach. Wagtail Parler is fit to you: it will allow you to use django-parler to translate your own models and still have a usefull wagtail interface to manage translations (via official wagtail's snippet admin but also with the old wagtail-modeladmin)

Installation

Install the package via pip. We consider you already have django-parler and wagtail installed.

pip install wagtail-parler

Then, in settings.py, add wagtail_parler to the installed apps.

# settings.py

INSTALLED_APPS = [
    # "wagtail.users" # for wagtail >= 7
    # …
    "wagtail_parler",
    # …
]

ATTENTION! Since wagtail 7, you need also to add wagtail.users in the installed app if not already done!

Basic Usage

You just have to add ParlerSnippetAdminMixin to your SnippetViewSet (or ParlerModelAdminMixin to your ModelAdmin), et voilà, you are ready to eat omelette du fromage.

from wagtail.snippets.views.snippets import SnippetViewSet
from wagtail.snippets.models import register_snippet
from wagtail_parler.handlers import ParlerSnippetAdminMixin
from .models import Food


class FoodAdmin(ParlerSnippetAdminMixin, SnippetViewSet):
    model = Food

register_snippet(FoodAdmin)

# or for an usage with wagtail-modeladmin:

from wagtail_modeladmin.options import ModelAdmin, modeladmin_register
from wagtail_parler.handlers import ParlerModelAdminMixin
from .models import Food

class FoodAdmin(ParlerModelAdminMixin, ModelAdmin):
    model = Food

modeladmin_register(FoodAdmin)

Maître Wagtail, sur un arbre perché,
Tenait en son bec une omelette du fromage.
Maître Webu, à l'envie de parler,
Lui tint à peu près ce langage :
Et bonjour, Monsieur Wagtail.
Que de beaux commits ! quelle merveille !
Sans mentir, si votre codage
Se rapporte à votre plumage,
Vous êtes le Phénix des hôtes de ces dépots. …
