PageChooserPanel
|
||||
----------------
|
||||
|
||||
**(In addition to these four, there are also Chooser Panels, detailed below.)**
|
||||
.. class:: PageChooserPanel(field_name, model=None)
|
||||
|
||||
You can explicitly link ``Page``-derived models together using the ``Page`` model and ``PageChooserPanel``.
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
from wagtail.wagtailcore.models import Page
|
||||
from wagtail.wagtailadmin.edit_handlers import PageChooserPanel
|
||||
|
||||
|
||||
class BookPage(Page):
|
||||
publisher = models.ForeignKey(
|
||||
'wagtailcore.Page',
|
||||
null=True,
|
||||
blank=True,
|
||||
on_delete=models.SET_NULL,
|
||||
related_name='+',
|
||||
)
|
||||
|
||||
content_panels = Page.content_panels + [
|
||||
PageChooserPanel('related_page', 'demo.PublisherPage'),
|
||||
]
|
||||
|
||||
``PageChooserPanel`` takes two arguments: a field name and an optional page type. Specifying a page type (in the form of an ``"appname.modelname"`` string) will filter the chooser to display only pages of that type.
|
||||
|
||||
ImageChooserPanel
|
||||
-----------------
|
||||
|
||||
.. class:: ImageChooserPanel(field_name)
|
||||
|
||||
One of the features of Wagtail is a unified image library, which you can access in your models through the ``Image`` model and the ``ImageChooserPanel`` chooser. Here's how:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
from wagtail.wagtailimages.models import Image
|
||||
from wagtail.wagtailimages.edit_handlers import ImageChooserPanel
|
||||
|
||||
|
||||
class BookPage(Page):
|
||||
cover = models.ForeignKey(
|
||||
'wagtailimages.Image',
|
||||
null=True,
|
||||
blank=True,
|
||||
on_delete=models.SET_NULL,
|
||||
related_name='+'
|
||||
)
|
||||
|
||||
content_panels = Page.content_panels + [
|
||||
ImageChooserPanel('cover'),
|
||||
]
|
||||
|
||||
Django's default behavior is to "cascade" deletions through a ForeignKey relationship, which is probably not what you want happening. This is why the ``null``, ``blank``, and ``on_delete`` parameters should be set to allow for an empty field. (See `Django model field reference (on_delete)`_ ). ``ImageChooserPanel`` takes only one argument: the name of the field.
|
||||
|
||||
.. _Django model field reference (on_delete): https://docs.djangoproject.com/en/dev/ref/models/fields/#django.db.models.ForeignKey.on_delete
|
||||
|
||||
Displaying ``Image`` objects in a template requires the use of a template tag. See :ref:`image_tag`.
|
||||
|
||||
DocumentChooserPanel
|
||||
--------------------
|
||||
|
||||
.. class:: DocumentChooserPanel(field_name)
|
||||
|
||||
For files in other formats, Wagtail provides a generic file store through the ``Document`` model:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
from wagtail.wagtaildocs.models import Document
|
||||
from wagtail.wagtaildocs.edit_handlers import DocumentChooserPanel
|
||||
|
||||
|
||||
class BookPage(Page):
|
||||
book_file = models.ForeignKey(
|
||||
'wagtaildocs.Document',
|
||||
null=True,
|
||||
blank=True,
|
||||
on_delete=models.SET_NULL,
|
||||
related_name='+'
|
||||
)
|
||||
|
||||
BookPage.content_panels = Page.content_panels + [
|
||||
DocumentChooserPanel('book_file'),
|
||||
]
|
||||
|
||||
As with images, Wagtail documents should also have the appropriate extra parameters to prevent cascade deletions across a ForeignKey relationship. ``DocumentChooserPanel`` takes only one argument: the name of the field.
|
||||
|
||||
SnippetChooserPanel
|
||||
-------------------
|
||||
|
||||
.. class:: SnippetChooserPanel(field_name, model)
|
||||
|
||||
Snippets are vanilla Django models you create yourself without a Wagtail-provided base class. So using them as a field in a page requires specifying your own ``appname.modelname``. A chooser, ``SnippetChooserPanel``, is provided which takes the field name and snippet class.
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
from wagtail.wagtailsnippets.edit_handlers import SnippetChooserPanel
|
||||
# ...
|
||||
class BookPage(Page):
|
||||
advert = models.ForeignKey(
|
||||
'demo.Advert',
|
||||
null=True,
|
||||
blank=True,
|
||||
on_delete=models.SET_NULL,
|
||||
related_name='+'
|
||||
)
|

content_panels = [
|

SnippetChooserPanel('advert', Advert),

]
