wagtaildraftail 0.6.0

With Pages

First, add a Draftail field to some of your pages. Here is an example:

from wagtaildraftail.fields import DraftailTextField

class MyPage(Page):
    body = DraftailTextField(blank=True)

    panels = [
        FieldPanel('body')
    ]

Then, when displaying those fields, use the richtext filter in the templates.

{% load wagtailcore_tags %}

{% block content %}
    {{ page.body|richtext }}
{% endblock %}

With StreamField

Here is an example using the ready-made block:

from wagtaildraftail.blocks import DraftailTextBlock

class MyStructBlock(StructBlock):
    body = DraftailTextBlock()

Configuration

Both DraftailTextField and DraftailTextBlock accept a string as keyword argument editor for a per field customisation.

Wagtail will look for a WAGTAILADMIN_RICH_TEXT_EDITORS constants in the settings, find the requested editor, load the defined widget and pass the options (if defined) to it.

Each editor defined in WAGTAILADMIN_RICH_TEXT_EDITORS is a dictionary with 2 keys:, WIDGET (mandatory) and OPTIONS (optional).

• WIDGET is a mandatory string set to the widget to use - should always be set to wagtaildraftail.widgets.DraftailTextArea (or a subclass of it) to work with Draft.js content

• OPTIONS is a dictionary which follows the format of Draftail configuration options. - Draftail options which are JavaScript values are hydrated at runtime in client/wagtaildraftail.js

WARNING: The type key for blockTypes, inlineStyles and entityTypes shouldn’t be changed. It is what defines how content is rendered, and is saved as a JSON blob in the database which would make migrations really painful.

WARNING: All the blocks/styles/entities defined in the editor config should have been configured to render properly in the exporter config.

Here is a sample configuration file. This should live in your Django settings.

Creating blocks and inline styles

TODO

Creating entities

An entity basically needs 4 elements:

• a page decorator.

• an editor decorator.

• an editor source.

• an editor strategy.

Decorators define how the content needs to be displayed on the site’s pages, as well as within the editor.

• For the pages, they are defined in Python with draftjs_exporter. Refer to the dedicated documentation on the draftjs_exporter README.

• For the editor, they are defined in JS/React with draftail. Refer to the dedicated documentation on the Draftail README.

Sources define the interface (usually a modal) through which the user will select an entity to insert into the editor.

Strategies allow the editor to identify entities when it is loaded. Strategies are optional as the default one works fine in most cases.

Both sources and strategies are defined in JS/React with draftail. Refer to the dedicated documentation on the Draftail README.

To register decorators, sources or strategies to wagtaildraftail, use the corresponding register function:

window.wagtailDraftail.registerDecorators({ LinkDecorator, ButtonDecorator });
window.wagtailDraftail.registerSources({ LinkSource });
window.wagtailDraftail.registerStrategies({ LinkStrategy });

Note: In order for wagtailDraftail and its register functions to be available in the global window namespace, make sure that wagtaildraftail appears before any other app which will try to register an entity in INSTALED_APPS.

npm run start

There are testing and linting tasks available both in the Makefile (Python) and package.json (JS).

Updating test data

Here are useful commands:

# Create new migrations from changes to the project.
python tests/manage.py makemigrations
# "Reset" the database.
rm db.sqlite3
# Generate fixtures from DB data. Remember to clean them up so they do not overlap with data from migrations.
python tests/manage.py dumpdata > tests/fixtures/test_data.json

Releases

• Make a new branch for the release of the new version.

• Update the CHANGELOG.

• Update the version number in wagtaildraftail/__init__.py and package.json, following semver.

• Make a PR and squash merge it.

• Back on master with the PR merged, use make publish (confirm, and enter your password).

• Finally, go to GitHub and create a release and a tag for the new version.

• Done!
