Wagtail 6.2 release notes¶

Content metrics¶

The page editor’s Checks panel now displays two content metrics: word count, and reading time. They are calculated based on the contents of the page preview, with a new mechanism to extract content from the previewed page for processing within the page editor. The Checks panel has also been redesigned to accommodate a wider breadth of types of checks, and interactive checks, in future releases.

This feature was developed by Albina Starykova and sponsored by The Motley Fool.

Concurrent editing notifications¶

When multiple users concurrently work on the same content, Wagtail now displays notifications to inform them of potential editing conflicts. When a user saves their work, other users are informed and presented with options: they can refresh the page to view the latest changes, or proceed with their own changes, overwriting the other user’s work.

Concurrent editing notifications are available for pages, and snippets. Specific messaging about conflicting versions is only available for pages and snippets with support for saving revisions. To configure how often notifications are updated, use WAGTAIL_EDITING_SESSION_PING_INTERVAL.

This feature was implemented by Matt Westcott and Sage Abdullah.

Alt text accessibility check¶

The built-in accessibility checker now enforces a new alt-text-quality rule, which tests alt text for the presence of known bad patterns such as file extensions and underscores. This rule is enabled by default, but can be disabled if necessary.

This feature was implemented by Albina Starykova, with support from the Wagtail accessibility team.

Universal listings designs for report views¶

All built-in and custom report views now use the Universal Listings visual design and filtering features introduced in all other listings in the admin interface over past releases. Thank you to Sage Abdullah for implementing this feature and continuing the rollout of the new designs.

Compact StreamField representation for migrations¶

StreamField definitions within migrations are now represented in a more compact form, where blocks that appear in multiple places within a StreamField structure are only defined once. For complex and deeply-nested StreamFields, this considerably reduces the size of migration files, and the memory consumption when loading them. This feature was developed by Matt Westcott.

Specifying a dict of distribution IDs for CloudFront cache invalidation is deprecated¶

Previous versions allowed passing a dict for DISTRIBUTION_ID within the WAGTAILFRONTENDCACHE configuration for a CloudFront backend, to allow specifying different distribution IDs for different hostnames. This is now deprecated; instead, multiple distribution IDs should be defined as multiple backends, with a HOSTNAMES parameter to define the hostnames associated with each one. For example, a configuration such as:

WAGTAILFRONTENDCACHE = {
    'cloudfront': {
        'BACKEND': 'wagtail.contrib.frontend_cache.backends.CloudfrontBackend',
        'DISTRIBUTION_ID': {
            'www.wagtail.org': 'your-distribution-id',
            'www.madewithwagtail.org': 'other-distribution-id',
        },
    },
}

should now be rewritten as:

WAGTAILFRONTENDCACHE = {
    'mainsite': {
        'BACKEND': 'wagtail.contrib.frontend_cache.backends.CloudfrontBackend',
        'DISTRIBUTION_ID': 'your-distribution-id',
        'HOSTNAMES': ['www.wagtail.org'],
    },
    'madewithwagtail': {
        'BACKEND': 'wagtail.contrib.frontend_cache.backends.CloudfrontBackend',
        'DISTRIBUTION_ID': 'other-distribution-id',
        'HOSTNAMES': ['www.madewithwagtail.org'],
    },
}

Changes to permissions registration for models with ModelViewSet and SnippetViewSet¶

Models registered with a ModelViewSet will now automatically have their Permission objects registered in the Groups administration area. Previously, you need to use the register_permissions hook to register them.

If you have a model registered with a ModelViewSet and you registered the model’s permissions using the register_permissions hook, you can now safely remove the hook.

If the viewset has inspect_view_enabled set to True, all permissions for the model are registered. Otherwise, the “view” permission is excluded from the registration.

To customize which permissions get registered for the model, you can override the get_permissions_to_register() method.

This behavior now applies to snippets as well. Previously, the “view” permission for snippets is always registered regardless of inspect_view_enabled. If you wish to register the “view” permission, you can enable the inspect view:

class FooViewSet(SnippetViewSet):
    ...
    inspect_view_enabled = True

Alternatively, if you wish to register the “view” permission without enabling the inspect view (i.e. the previous behavior), you can override get_permissions_to_register like the following:

from django.contrib.auth.models import Permission
from django.contrib.contenttypes.models import ContentType

class FooViewSet(SnippetViewSet):
    def get_permissions_to_register(self):
        content_type = ContentType.objects.get_for_model(self.model)
        return Permission.objects.filter(content_type=content_type)

Deprecation of WAGTAIL_USER_EDIT_FORM, WAGTAIL_USER_CREATION_FORM, and WAGTAIL_USER_CUSTOM_FIELDS settings¶

This release introduces a customizable UserViewSet class, which can be used to customize various aspects of Wagtail’s admin views for managing users, including the form classes for creating and editing users. As a result, the WAGTAIL_USER_EDIT_FORM, WAGTAIL_USER_CREATION_FORM, and WAGTAIL_USER_CUSTOM_FIELDS settings have been deprecated in favor of customizing the form classes via UserViewSet.get_form_class().

If you use the aforementioned settings, you can migrate your code by making the following changes.

class User(AbstractUser):
    country = models.CharField(verbose_name='country', max_length=255)
    status = models.ForeignKey(MembershipStatus, on_delete=models.SET_NULL, null=True, default=1)

class CustomUserEditForm(UserEditForm):
    status = forms.ModelChoiceField(queryset=MembershipStatus.objects, required=True, label=_("Status"))


class CustomUserCreationForm(UserCreationForm):
    status = forms.ModelChoiceField(queryset=MembershipStatus.objects, required=True, label=_("Status"))

WAGTAIL_USER_EDIT_FORM = "myapp.forms.CustomUserEditForm"
WAGTAIL_USER_CREATION_FORM = "myapp.forms.CustomUserCreationForm"
WAGTAIL_USER_CUSTOM_FIELDS = ["country", "status"]

class CustomUserEditForm(UserEditForm):
    status = forms.ModelChoiceField(queryset=MembershipStatus.objects, required=True, label=_("Status"))

    # Use ModelForm's automatic form fields generation for the model's `country` field,
    # but use an explicit custom form field for `status`.
    # This replaces the `WAGTAIL_USER_CUSTOM_FIELDS` setting.
    class Meta(UserEditForm.Meta):
        fields = UserEditForm.Meta.fields | {"country", "status"}

class CustomUserCreationForm(UserCreationForm):
    status = forms.ModelChoiceField(queryset=MembershipStatus.objects, required=True, label=_("Status"))

    # Use ModelForm's automatic form fields generation for the model's `country` field,
    # but use an explicit custom form field for `status`.
    # This replaces the `WAGTAIL_USER_CUSTOM_FIELDS` setting.
    class Meta(UserCreationForm.Meta):
        fields = UserEditForm.Meta.fields | {"country", "status"}

# myapp/viewsets.py
from wagtail.users.views.users import UserViewSet as WagtailUserViewSet

from .forms import CustomUserCreationForm, CustomUserEditForm


class UserViewSet(WagtailUserViewSet):
    # This replaces the WAGTAIL_USER_EDIT_FORM and WAGTAIL_USER_CREATION_FORM settings
    def get_form_class(self, for_update=False):
        if for_update:
            return CustomUserEditForm
        return CustomUserCreationForm

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


class CustomUsersAppConfig(WagtailUsersAppConfig):
    user_viewset = "myapp.viewsets.UserViewSet"
    # If you have customized the GroupViewSet before
    group_viewset = "myapp.viewsets.GroupViewSet"

INSTALLED_APPS = [
    ...,
    # Make sure you have two separate entries for the custom user model's app
    # and the custom app config for the wagtail.users app
    "myapp",  # an app that contains the custom user model
    "myproject.apps.CustomUsersAppConfig",  # a custom app config for the wagtail.users app
    # "wagtail.users",  # this should be removed in favour of the custom app config
    ...,
]

Changes to report views with the new Universal Listings UI¶

The report views have been reimplemented to use the new Universal Listings UI, which introduces AJAX-based filtering and support for the wagtail.admin.ui.tables framework. As a result, a number of changes have been made to the ReportView and PageReportView classes, as well as their templates.

If you have custom report views as documented in Adding reports, you will need to make the following changes.

 class UnpublishedChangesReportView(PageReportView):
-    title = "Pages with unpublished changes"
+    page_title = "Pages with unpublished changes"

 class UnpublishedChangesReportView(PageReportView):
+    index_url_name = "unpublished_changes_report"
+    index_results_url_name = "unpublished_changes_report_results"

 @hooks.register("register_admin_urls")
 def register_unpublished_changes_report_url():
     return [
         path("reports/unpublished-changes/", UnpublishedChangesReportView.as_view(), name="unpublished_changes_report"),
+        # Add a results-only view to add support for AJAX-based filtering
+        path("reports/unpublished-changes/results/", UnpublishedChangesReportView.as_view(results_only=True), name="unpublished_changes_report_results"),
     ]

 class UnpublishedChangesReportView(PageReportView):
-    template_name = "reports/unpublished_changes_report.html"
+    results_template_name = "reports/unpublished_changes_report_results.html"

 {# <project>/templates/reports/unpublished_changes_report_results.html #}

-{% extends "wagtailadmin/reports/base_page_report.html" %}
+{% extends "wagtailadmin/reports/base_page_report_results.html" %}

-{% block listing %}
+{% block results %}
     {% include "reports/include/_list_unpublished_changes.html" %}
 {% endblock %}
-{% block no_results %}
+{% block no_results_message %}
     <p>No pages with unpublished changes.</p>
 {% endblock %}

class CustomNonPageReportView(ReportView):
    template_name = "reports/custom_non_page_report.html"

{# <project>/templates/reports/custom_non_page_report.html #}
{% extends "wagtailadmin/reports/base_report.html" %}

{% block results %}
    {% if object_list %}
        <table class="listing">
            <!-- Table markup goes here -->
        </table>
    {% else %}
        <p>No results found.</p>
    {% endif %}
{% endblock %}

class CustomNonPageReportView(ReportView):
    results_template_name = "reports/custom_non_page_report_results.html"

{# <project>/templates/reports/custom_non_page_report_results.html #}
{% extends "wagtailadmin/reports/base_report_results.html" %}

{% block results %}
    <table class="listing">
        <!-- Table markup goes here -->
    </table>
{% endblock %}

{% block no_results_message %}
    <p>No results found.</p>
{% endblock %}

Deprecation of window.ActivateWorkflowActionsForDashboard and window.ActivateWorkflowActionsForEditView¶

The undocumented usage of the JavaScript window.ActivateWorkflowActionsForDashboard and window.ActivateWorkflowActionsForEditView functions will be removed in a future release.

These functions are only used by Wagtail to initialize event listeners to workflow action buttons via inline scripts and are never intended to be used in custom code. The inline scripts have been removed in favour of initializing the event listeners directly in the included workflow-action.js script. As a result, the functions no longer need to be globally-accessible.

Any custom workflow actions should be done using the documented approach for customizing the behavior of custom task types, such as by overriding Task.get_actions().
