wagtailmedia

A module for Wagtail that provides functionality similar to wagtail.documents module, but for audio and video files.

Install

Install using pip:

pip install wagtailmedia

wagtailmedia is compatible with Wagtail 2.15 and above. Check out older releases for compatibility with older versions of Wagtail.

Settings

In your settings file, add wagtailmedia to INSTALLED_APPS:

INSTALLED_APPS = [
    # ...
    "wagtailmedia",
    # ...
]

All wagtailmedia settings are defined in a single WAGTAILMEDIA dictionary in your settings file:

# settings.py

WAGTAILMEDIA = {
    "MEDIA_MODEL": "",  # string, dotted-notation. Defaults to "wagtailmedia.Media"
    "MEDIA_FORM_BASE": "",  # string, dotted-notation. Defaults to an empty string
    "AUDIO_EXTENSIONS": [],  # list of extensions
    "VIDEO_EXTENSIONS": [],  # list of extensions
}

AUDIO_EXTENSIONS defaults to "aac", "aiff", "flac", "m4a", "m4b", "mp3", "ogg" and "wav". VIDEO_EXTENSIONS defaults to "avi", "h264", "m4v", "mkv", "mov", "mp4", "mpeg", "mpg", "ogv" and "webm".

URL configuration

Your project needs to be set up to serve user-uploaded files from MEDIA_ROOT. Your Django project may already have this in place, but if not, add the following snippet to urls.py:

from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    # ... the rest of your URLconf goes here ...
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

Note that this only works in development mode (DEBUG = True); in production, you will need to configure your web server to serve files from MEDIA_ROOT. For further details, see the Django documentation: Serving files uploaded by a user during development and Deploying static files.

With this configuration in place, you are ready to run ./manage.py migrate to create the database tables used by wagtailmedia.

wagtailmedia loads additional assets for the chooser panel interface. Run ./manage.py collectstatic after the migrations step to collect all the required assets.

Custom Media model

The Media model can be customised. To do this, you need to add a new model to your project that inherits from wagtailmedia.models.AbstractMedia.

Then set the MEDIA_MODEL attribute in the WAGTAILMEDIA settings dictionary to point to it:

# settings.py
WAGTAILMEDIA = {
    "MEDIA_MODEL": "my_app.CustomMedia",
    # ...
}

You can customize the model form used with your Media model using the MEDIA_FORM_BASE setting. It should be the dotted path to the form and will be used as the base form passed to modelform_factory() when constructing the media form.

# settings.py

WAGTAILMEDIA = {
    "MEDIA_FORM_BASE": "my_app.forms.CustomMediaForm",
    # ...
}

Hooks

construct_media_chooser_queryset

Called when rendering the media chooser view, to allow the media listing QuerySet to be customised. The callable passed into the hook will receive the current media QuerySet and the request object, and must return a Media QuerySet (either the original one, or a new one).

from wagtail.core import hooks


@hooks.register("construct_media_chooser_queryset")
def show_my_uploaded_media_only(media, request):
    # Only show uploaded media
    media = media.filter(uploaded_by_user=request.user)

    return media

How to use

As a regular Django field

You can use Media as a regular Django field. Here’s an example:

from django.db import models

from wagtail.wagtailcore.models import Page
from wagtail.wagtailcore.fields import RichTextField
from wagtail.wagtailadmin.edit_handlers import FieldPanel

from wagtailmedia.edit_handlers import MediaChooserPanel


class BlogPageWithMedia(Page):
    author = models.CharField(max_length=255)
    date = models.DateField("Post date")
    body = RichTextField(blank=False)
    featured_media = models.ForeignKey(
        "wagtailmedia.Media",
        null=True,
        blank=True,
        on_delete=models.SET_NULL,
        related_name="+",
    )

    content_panels = Page.content_panels + [
        FieldPanel("author"),
        FieldPanel("date"),
        FieldPanel("body"),
        MediaChooserPanel("featured_media"),
    ]

The MediaChooserPanel accepts the media_type keyword argument (kwarg) to limit the types of media that can be chosen or uploaded. At the moment only "audio" (MediaChooserPanel(media_type="audio")) and "video" (MediaChooserPanel(media_type="audio")) are supported, and any other type will make the chooser behave as if it did not get any kwarg.

Name clash with Wagtail

Do not name the field media. When rendering the admin UI, Wagtail uses a media property for its fields’ CSS & JS assets loading. Using media as a field name breaks the admin UI (#54).

In StreamField

You can use Media in StreamField. To do this, you need to add a new block class that inherits from wagtailmedia.blocks.AbstractMediaChooserBlock and implement your own render_basic method.

Here is an example:

from django.db import models
from django.forms.utils import flatatt
from django.utils.html import format_html, format_html_join

from wagtail.wagtailcore.models import Page
from wagtail.wagtailcore.fields import StreamField
from wagtail.wagtailcore import blocks
from wagtail.wagtailadmin.edit_handlers import FieldPanel, StreamFieldPanel

from wagtailmedia.blocks import AbstractMediaChooserBlock


class TestMediaBlock(AbstractMediaChooserBlock):
    def render_basic(self, value, context=None):
        if not value:
            return ""

        if value.type == "video":
            player_code = """
            <div>
                <video width="320" height="240" controls>
                    {0}
                    Your browser does not support the video tag.
                </video>
            </div>
            """
        else:
            player_code = """
            <div>
                <audio controls>
                    {0}
                    Your browser does not support the audio element.
                </audio>
            </div>
            """

        return format_html(
            player_code,
            format_html_join(
                "\n", "<source{0}>", [[flatatt(s)] for s in value.sources]
            ),
        )


class BlogPage(Page):
    author = models.CharField(max_length=255)
    date = models.DateField("Post date")
    body = StreamField(
        [
            ("heading", blocks.CharBlock(classname="full title", icon="title")),
            ("paragraph", blocks.RichTextBlock(icon="pilcrow")),
            ("media", TestMediaBlock(icon="media")),
        ]
    )

    content_panels = Page.content_panels + [
        FieldPanel("author"),
        FieldPanel("date"),
        StreamFieldPanel("body"),
    ]

You can also use audio or video-specific choosers:

# ...
from wagtailmedia.blocks import AudioChooserBlock, VideoChooserBlock


class BlogPage(Page):
    # ...

    body = StreamField(
        [
            # ... other block definitions
            ("audio", AudioChooserBlock(icon="media")),
            ("video", VideoChooserBlock(icon="media")),
        ]
    )
