Wagtail 2.10 release notes¶

Moderation workflow¶

This release introduces a configurable moderation workflow system to replace the single-step “submit for moderation” feature. Workflows can be set up on specific subsections of the page tree and consist of any number of tasks to be completed by designated user groups. To support this, numerous UI improvements have been made to Wagtail’s page editor, including a new log viewer to track page history.

For further details, see our How-to: Configure workflows for moderation and Adding new Task types.

This feature was developed by Jacob Topp-Mugglestone, Karl Hobley, Matt Westcott and Dan Braghis, and sponsored by The Motley Fool.

Django 3.1 support¶

This release adds support for Django 3.1. Compatibility fixes were contributed by Matt Westcott and Karl Hobley.

Search query expressions¶

Search queries can now be constructed as structured expressions in the manner of the Django ORM’s Q() values, allowing for complex queries that combine individual terms, phrases and boosting. A helper function parse_query_string is provided to convert “natural” queries containing quoted phrases into these expressions. For complete documentation, see Complex search queries. This feature was developed by Karl Hobley and sponsored by The Motley Fool.

Redirect importing¶

Redirects can now be imported from an uploaded CSV, TSV, XLS or XLSX file. This feature was developed by Martin Sandström.

Removed support for Python 3.5¶

Python 3.5 is no longer supported as of this release; please upgrade to Python 3.6 or above before upgrading Wagtail.

Move to new configurable moderation system (workflow)¶

A new workflow system has been introduced for moderation. Task types are defined as models in code, and instances - tasks - are created in the Wagtail Admin, then chained together to form workflows: sequences of moderation stages through which a page must pass prior to publication.

Key points:

• Prior to 2.10, moderation in Wagtail was performed on a per-revision basis: once submitted, the moderator would approve or reject the submitted revision only, which would not include subsequent changes. Moderation is now performed per page, with moderators always seeing the latest revision.

• PageRevision.submitted_for_moderation will return True for revisions passing through the old moderation system, but not for the new system

• Pages undergoing moderation in the old system will not have their moderation halted, and can still be approved/rejected. As a result, you may see two sets of moderation dashboard panels until there are no longer any pages in moderation in the old system

• No pages can be submitted for moderation in the old system: “Submit for moderation” now submits to the new Workflow system

• You no longer need the publish permission to perform moderation actions on a page - actions available to each user are now configured per task. With the built in GroupApprovalTask, anybody in a specific set of groups can approve or reject the task.

• A data migration is provided to recreate your existing publish-permission based moderation workflow in the new system. If you have made no permissions changes, this should simply create a task approvable by anybody in the Moderators group, and assign a workflow with this task to the root page, creating a standard workflow for the entire page tree. However, if you have a complex nested set of publish page permissions, the created set of workflows will be more complex as well - you may wish to inspect the created workflows and tasks in the new Settings/Workflows admin area and potentially simplify them. See our How-to: Configure workflows for moderation for the administrator guide.

<div class="rich-text"> wrappers removed from rich text¶

In previous releases, rich text values were enclosed in a <div class="rich-text"> element when rendered; this element has now been removed. To restore the old behaviour, see Legacy richtext.

Prepopulating data for site history report¶

This release introduces logging of user actions, viewable through the “Site history” report. To pre-populate these logs with data from page revision history, run the management command: ./manage.py create_log_entries_from_revisions.

clean_name field added to form builder form field models¶

A clean_name field has been added to form field models that extend AbstractForm. This is used as the name attribute of the HTML form field, and the dictionary key that the submitted form data is stored under. Storing this on the model (rather than calculating it on-the-fly as was done previously) ensures that if the algorithm for generating the clean name changes in future, the existing data will not become inaccessible. A future version of Wagtail will drop the unidecode library currently used for this.

For forms created through the Wagtail admin interface, no action is required, as the new field will be populated on server startup. However, any process that creates form pages through direct insertion on the database (such as loading from fixtures) should now be updated to populate clean_name.

New next_url keyword argument on register_page_listing_buttons and register_page_listing_more_buttons hooks¶

Functions registered through the hooks register_page_listing_buttons and register_page_listing_more_buttons now accept an additional keyword argument next_url. A hook function currently written as:

@hooks.register('register_page_listing_buttons')
def page_listing_more_buttons(page, page_perms, is_parent=False):
    yield wagtailadmin_widgets.Button(
        'My button', '/goes/to/a/url/', priority=60
    )

should now become:

@hooks.register('register_page_listing_buttons')
def page_listing_more_buttons(page, page_perms, is_parent=False, next_url=None):
    yield wagtailadmin_widgets.Button(
        'My button', '/goes/to/a/url/', priority=60
    )

The next_url argument specifies a URL to redirect back to after the action is complete, and can be passed as a query parameter to the linked URL, if the view supports it.
