wagtail-shortcode 1.0.3

Draftail Shortcode Entity, adds link-like shortcodes to Draftail.

Wagtail shortcode

Wagtail shortcode adds a custom Draftail enitity to provide a custom linktype ("shortcode"), giving you the ability to assign values in a similar way to normal links as well as decide how they should be rendered on the page.

Installation

• python -m pip install wagtail-shortcode
• ...

Add 'wagtail_shortcode' to INSTALLED_APPS.

Register a LinkHandler, to control how the new linktype renders on the front-end (|richtext filter).

LinkHandlers must be registered within a wagtail_hooks.py file under an app directory and use an identifier matching SHORTCODE_ANCHOR_TARGET_IDENTIFIER, for example:

# ./utils_app/wwgtail_hooks.py
from django.utils.html import escape
from wagtail import hooks
from wagtail.rich_text import LinkHandler
from wagtail_shortcode.handlers import SHORTCODE_ANCHOR_TARGET_IDENTIFIER


class CustomShortcodeLinkHandler(LinkHandler):
    identifier = SHORTCODE_ANCHOR_TARGET_IDENTIFIER

    @classmethod
    def expand_db_attributes(cls, attrs):
        href = attrs["shortcode"]
        # Do something clever
        return '<a href="%s">' % escape(href)


@hooks.register("register_rich_text_features")
def register_shortcode_link(features):
    features.register_link_type(CustomShortcodeLinkHandler)

Add shortcode to the features argument of any rich text field where you have overridden the default feature list:

class Header(models.Model):
    content = RichTextField(
        features=["shortcode", "h2", "h3", "bold", "italic", "link"]
    )

Configuration

Updating the window prompt's help-text

When adding shortcode within the editor, a window prompt will appear, the text within this prompt can be customised by providing a value for SHORTCODE_HELP_TEXT within your project's settings file. This can be helpful as to inform editors of the expected behaviour of your custom LinkHandler.

SHORTCODE_HELP_TEXT="Enter a shortcode value"

The window.prompt function is a JavaScript method which supports basic text formatting using special characters, as such a newline character can be included using \n if needed.
