Bynder is a Digital Asset Management System (DAMS) and platform that allows organisations to manage their digital assets, which includes the images and documents used in Wagtail content.

The data flow is one way: Bynder assets are always treated as the source of truth, and Wagtail uses read-only API access to create copies of assets and keep them up-to-date.

How it works

The main points of integration are Wagtail's image and document chooser views, which are patched by this app to show an asset selection UI for Bynder instead of a list of Wagtail images or documents.

When an asset is selected, Wagtail silently downloads the file and related metadata, and saves it as an Image or Document object, allowing it to be used in a typical way. The ID of the selected asset (as well as a few other bits of data) are saved on the object when this happens, helping Wagtail to recognise when it already has a copy of an asset, and to help keep them up-to-date with changes made in Bynder.

Currently, changes are synced from Bynder back to Wagtail via a few well-optimised management commands, intended to be run regularly (via a cron job):

• python manage.py update_stale_images
• python manage.py update_stale_documents
• python manage.py update_stale_videos

By default, these commands only fetch data for assets updated within the last 24 hours. However, you can use the minutes, hours or days options to narrow or widen this timespan. For example:

To sync images updated within the last 30 minutes only:

$ python manage.py update_stale_images --minutes=30

To sync images updated within the last three hours only:

$ python manage.py update_stale_images --hours=3

To sync images updated within the last three days:

$ python manage.py update_stale_images --days=3

Installation

In your project's Django settings, add the app your INSTALLED_APPS list (at the end is fine):

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

Then add the following to the MIDDLEWARE list (at the end is fine):

MIDDLEWARE = [
  #...
  "wagtail_bynder.middleware.PatchWagtailURLsMiddleware",
]

Import the abstract BynderSyncedImage model and have your project's custom image model definition subclass it instead of wagtail.images.models.AbstractImage. For example

# yourproject/images/models.py
from wagtail_bynder.models import BynderSyncedImage


class CustomImage(BynderSyncedImage):
    pass

Import the abstract BynderSyncedDocument model and have your project's custom document model definition subclass it instead of wagtail.documents.models.AbstractDocument. For example:

# yourproject/documents/models.py
from wagtail_bynder.models import BynderSyncedDocument


class CustomDocument(BynderSyncedDocument):
    pass

Finally, run Django's makemigrations and migrate commands to apply any model field changes to your project

$ python manage.py makemigrations
$ python manage.py migrate

Optional: To use videos from Bynder

To use videos from Bynder in content across the site, this app includes a specialised model to help store relevant data for videos, plus blocks and chooser widgets to help use them in your project. However, because not all projects use video, and project-specific requirements around video usage can be a little more custom, the model is abstract - you need to subclass it in order to use the functionality.

First, ensure you have wagtail.snippets in your project's INSTALLED_APPS:

INSTALLED_APPS = [
  # ...
  "wagtail.users",
  "wagtail.admin",
  "wagtail.documents",
  "wagtail.images",
  "wagtail.snippets",
  "wagtail",
   # ...
]

Next, import the abstract BynderSyncedVideo model and subclass it within your project to create a concrete model. For example:

# yourproject/videos/models.py
from wagtail_bynder.models import BynderSyncedVideo


class Video(BynderSyncedVideo):
    pass

Then, in your project's Django settings, add a BYNDER_VIDEO_MODEL item to establish your custom model as the 'official' video model. The value should be a string in the format "app_label.Model". For example:

BYNDER_VIDEO_MODEL = "videos.Video"

Finally, run Django's makemigrations and migrate commands to create and apply the model changes in your project.

$ python manage.py makemigrations
$ python manage.py migrate

Configuration

You can use the following settings to configure the integration:

BYNDER_DOMAIN

Example: "your-org.bynder.com"

Default: None

The Bynder instance you want the environment to use.

BYNDER_API_TOKEN

Example: "60ae04f68460cfed1b289c4c1db4c9b273b238dx2030c51298dcad245b5ff1f8"

Default: None

An API token for the back end to use when talking to the Bynder API. NOTE: This could be more permissive than BYNDER_COMPACTVIEW_API_TOKEN, so should be kept separate to avoid surfacing to Wagtail users.

BYNDER_COMPACTVIEW_API_TOKEN

Example: "64ae04f71460cfed1b289c4c1db4c9b273b238dx2030c51298dcad245b5ff1f8"

Default: None

An API token for Bynder's JavaScript 'compact view' to use. The value is injected into the admin_base.html template for Wagtail for the JavaScript to pick up, exposing it to Wagtail users. Because of this, it should be different to BYNDER_API_TOKEN and only needs to have basic read permissions.

BYNDER_IMAGE_SOURCE_THUMBNAIL_NAME

Example: "WagtailSource"

Default: "webimage"

The name of the automatically generated derivative that should be downloaded and used as the file value for the representative Wagtail image (as it appears in thumbnails in the API representation).

WARNING: It's important to get this right, because if the specified derivative is NOT present in the response for an image for any reason, the ORIGINAL will be downloaded - which will lead to slow chooser response times and higher memory usage when generating renditions.

BYNDER_VIDEO_MODEL

Example: "video.Video"

Default: None

BYNDER_VIDEO_PRIMARY_DERIVATIVE_NAME

Default: "Web-Primary"

BYNDER_VIDEO_FALLBACK_DERIVATIVE_NAME

Default: "Web-Fallback"

BYNDER_VIDEO_POSTER_IMAGE_DERIVATIVE_NAME

Default: "webimage"

BYNDER_SYNC_EXISTING_IMAGES_ON_CHOOSE

Example: True

Default: False

When True, local copies of images will be refreshed from the Bynder API representation whenever they are selected in the chooser interface. This slows down the chooser experience slightly, but can be useful for seeing up-to-date data in environments that might not be using the management commands or other means to keep images up-to-date with their Bynder counterparts.

BYNDER_SYNC_EXISTING_DOCUMENTS_ON_CHOOSE

Example: True

Default: False

As BYNDER_SYNC_EXISTING_IMAGES_ON_CHOOSE, but for documents.

BYNDER_SYNC_EXISTING_VIDEOS_ON_CHOOSE

Example: True

Default: False

As BYNDER_SYNC_EXISTING_IMAGES_ON_CHOOSE, but for videos.

BYNDER_DISABLE_WAGTAIL_EDITING_FOR_ASSETS

Example: True

Default: False

When True, hitting Wagtail's built-in edit view for an image or document will result in a redirect to the asset detail view in the Bynder interface.

The default is value is False, because it can be useful to use the Wagtail representation to check that file, metadata and focal points are being accurately reflected.
