Customizing group edit/create views

The views for managing groups within the app are collected into a 'viewset' class, which acts as a single point of reference for all shared components of those views, such as forms. By subclassing the viewset, it is possible to override those components and customize the behavior of the group management interface.

Custom edit/create forms

This example shows how to customize forms on the 'edit group' and 'create group' views in the Wagtail admin.

Let's say you need to connect Active Directory groups with Django groups. We create a model for Active Directory groups as follows:

# myapp/models.py
from django.contrib.auth.models import Group
from django.db import models


class ADGroup(models.Model):
    guid = models.CharField(verbose_name="GUID", max_length=64, db_index=True, unique=True)
    name = models.CharField(verbose_name="Group", max_length=255)
    domain = models.CharField(verbose_name="Domain", max_length=255, db_index=True)
    description = models.TextField(verbose_name="Description", blank=True, null=True)
    roles = models.ManyToManyField(Group, verbose_name="Role", related_name="adgroups", blank=True)

class Meta:
    verbose_name = "AD group"
    verbose_name_plural = "AD groups"

However, there is no role field on the Wagtail group 'edit' or 'create' view. To add it, inherit from wagtail.users.forms.GroupForm and add a new field:

# myapp/forms.py
from django import forms

from wagtail.users.forms import GroupForm as WagtailGroupForm

from .models import ADGroup


class GroupForm(WagtailGroupForm):
    adgroups = forms.ModelMultipleChoiceField(
        label="AD groups",
        required=False,
        queryset=ADGroup.objects.order_by("name"),
    )

    class Meta(WagtailGroupForm.Meta):
        fields = WagtailGroupForm.Meta.fields + ("adgroups",)

    def __init__(self, initial=None, instance=None, **kwargs):
        if instance is not None:
            if initial is None:
                initial = {}
            initial["adgroups"] = instance.adgroups.all()
        super().__init__(initial=initial, instance=instance, **kwargs)

    def save(self, commit=True):
        instance = super().save()
        instance.adgroups.set(self.cleaned_data["adgroups"])
        return instance

Now add your custom form into the group viewset by inheriting the default Wagtail GroupViewSet class and overriding the get_form_class method.

# myapp/viewsets.py
from wagtail.users.views.groups import GroupViewSet as WagtailGroupViewSet

from .forms import GroupForm


class GroupViewSet(WagtailGroupViewSet):
    def get_form_class(self, for_update=False):
        return GroupForm

Add the field to the group 'edit'/'create' templates:

{% extends "wagtailusers/groups/edit.html" %}
{% load wagtailusers_tags wagtailadmin_tags i18n %}

{% block extra_fields %}
    <li>{% include "wagtailadmin/shared/field.html" with field=form.adgroups %}</li>
{% endblock extra_fields %}

Finally, we configure the wagtail.users application to use the custom viewset, by setting up a custom AppConfig class. Within your project folder (which will be the package containing the top-level settings and urls modules), create apps.py (if it does not exist already) and add:

# myproject/apps.py
from wagtail.users.apps import WagtailUsersAppConfig


class CustomUsersAppConfig(WagtailUsersAppConfig):
    group_viewset = "myapp.viewsets.GroupViewSet"

Replace wagtail.users in settings.INSTALLED_APPS with the path to CustomUsersAppConfig.

INSTALLED_APPS = [
    ...,
    "myproject.apps.CustomUsersAppConfig",
    # "wagtail.users",
    ...,
]

The GroupViewSet class is a subclass of {class}~wagtail.admin.viewsets.model.ModelViewSet and thus it supports most of the customizations available for ModelViewSet.

The user forms and views can be customized in a similar way - see [](custom_userviewset).

(customizing_group_views_permissions_order)=

Customizing the group editor permissions ordering

The order in which object types appear in the group editor's "Object permissions" and "Other permissions" sections can be configured by registering that order in one or more AppConfig definitions. The order value is typically an integer between 0 and 999, although this is not enforced.

from django.apps import AppConfig


class MyProjectAdminAppConfig(AppConfig):
    name = "myproject_admin"
    verbose_name = "My Project Admin"

    def ready(self):
        from wagtail.users.permission_order import register

        register("gadgets.SprocketType", order=150)
        register("gadgets.ChainType", order=151)
        register("site_settings.Settings", order=160)

A model class can also be passed to register().

Any object types that are not explicitly given an order will be sorted in alphabetical order by app_label and model, and listed after all of the object types with a configured order.
