Customising the tabbed interface

As standard, Wagtail organises panels for pages into three tabs: 'Content', 'Promote' and 'Settings'. For snippets Wagtail puts all panels into one page. Depending on the requirements of your site, you may wish to customise this for specific page types or snippets - for example, adding an additional tab for sidebar content. This can be done by specifying an ``edit_handler`` attribute on the page or snippet model. For example:
|
|
|
|
.. code-block:: python
|
|
|
|
from wagtail.wagtailadmin.edit_handlers import TabbedInterface, ObjectList
|
|
|
|
class BlogPage(Page):
|
|
# field definitions omitted
|
|
|
|
content_panels = [
|
|
FieldPanel('title', classname="full title"),
|
|
FieldPanel('date'),
|
|
FieldPanel('body', classname="full"),
|
|
]
|
|
sidebar_content_panels = [
|
|
SnippetChooserPanel('advert'),
|
|
InlinePanel('related_links', label="Related links"),
|
|
]
|
|
|
|
edit_handler = TabbedInterface([
|
|
ObjectList(content_panels, heading='Content'),
|
|
ObjectList(sidebar_content_panels, heading='Sidebar content'),
|
|
ObjectList(Page.promote_panels, heading='Promote'),
|
|
ObjectList(Page.settings_panels, heading='Settings', classname="settings"),
|
|
])

Rich Text (HTML)
|
|
~~~~~~~~~~~~~~~~
|
|
|
|
Wagtail provides a general-purpose WYSIWYG editor for creating rich text content (HTML) and embedding media such as images, video, and documents. To include this in your models, use the :class:`~wagtail.wagtailcore.fields.RichTextField` function when defining a model field:
|
|
|
|
.. code-block:: python
|
|
|
|
from wagtail.wagtailcore.fields import RichTextField
|
|
from wagtail.wagtailadmin.edit_handlers import FieldPanel
|
|
|
|
|
|
class BookPage(Page):
|
|
book_text = RichTextField()
|
|
|
|
content_panels = Page.content_panels + [
|
|
FieldPanel('body', classname="full"),
|
|
]
|
|
|
|
:class:`~wagtail.wagtailcore.fields.RichTextField` inherits from Django's basic ``TextField`` field, so you can pass any field parameters into :class:`~wagtail.wagtailcore.fields.RichTextField` as if using a normal Django field. This field does not need a special panel and can be defined with ``FieldPanel``.
|
|
|
|
However, template output from :class:`~wagtail.wagtailcore.fields.RichTextField` is special and need to be filtered to preserve embedded content. See :ref:`rich-text-filter`.
|
|
|
|
If you're interested in extending the capabilities of the Wagtail WYSIWYG editor (``hallo.js``), See :ref:`extending_wysiwyg`.

Extending the WYSIWYG Editor (``hallo.js``)
|
|
-------------------------------------------
|
|
|
|
To inject JavaScript into the Wagtail page editor, see the :ref:`insert_editor_js <insert_editor_js>` hook. Once you have the hook in place and your ``hallo.js`` plugin loads into the Wagtail page editor, use the following JavaScript to register the plugin with ``hallo.js``.
|
|
|
|
.. code-block:: javascript
|
|
|
|
registerHalloPlugin(name, opts);
|
|
|
|
``hallo.js`` plugin names are prefixed with the ``"IKS."`` namespace, but the ``name`` you pass into ``registerHalloPlugin()`` should be without the prefix. ``opts`` is an object passed into the plugin.
|
|
|
|
For information on developing custom ``hallo.js`` plugins, see the project's page: https://github.com/bergie/hallo

.. _rich_text_image_formats:

|
Image Formats in the Rich Text Editor
|
|
-------------------------------------
|
|
|
|
On loading, Wagtail will search for any app with the file ``image_formats.py`` and execute the contents. This provides a way to customise the formatting options shown to the editor when inserting images in the :class:`~wagtail.wagtailcore.fields.RichTextField` editor.
|
|
|
|
As an example, add a "thumbnail" format:
|
|
|
|
.. code-block:: python
|
|
|
|
# image_formats.py
|
|
from wagtail.wagtailimages.formats import Format, register_image_format
|
|
|
|
register_image_format(Format('thumbnail', 'Thumbnail', 'richtext-image thumbnail', 'max-120x120'))
|
|
|
|
|
|
To begin, import the ``Format`` class, ``register_image_format`` function, and optionally ``unregister_image_format`` function. To register a new ``Format``, call the ``register_image_format`` with the ``Format`` object as the argument. The ``Format`` class takes the following constructor arguments:
|
|
|
|
``name``
|
|
The unique key used to identify the format. To unregister this format, call ``unregister_image_format`` with this string as the only argument.
|
|
|
|
``label``
|
|
The label used in the chooser form when inserting the image into the :class:`~wagtail.wagtailcore.fields.RichTextField`.
|
|
|
|
``classnames``
|
|
The string to assign to the ``class`` attribute of the generated ``<img>`` tag.
|
|
|
|
.. note::
|
|
Any class names you provide must have CSS rules matching them written separately, as part of the front end CSS code. Specifying a ``classnames`` value of ``left`` will only ensure that class is output in the generated markup, it won't cause the image to align itself left.
|
|
|
|
``filter_spec``
|
|
The string specification to create the image rendition. For more, see the :ref:`image_tag`.
|
|
|
|
|
|
To unregister, call ``unregister_image_format`` with the string of the ``name`` of the ``Format`` as the only argument.
