Entity Embed Module

Allows any entity to be embedded using a WYSIWYG and text format.

Requirements

• Latest dev release of Drupal 8.x as this module will not work with the last alpha release.

Configuration

• Install and enable the module.
• Enable the entity-embed filter 'Display embedded entities' for the desired text formats from the configuration page: '/admin/config/content/formats'.
• Add <drupal-entity> to the 'Allowed HTML tags'
• To enable the WYSIWYG plugin, move the entity-embed 'E' button into the Active toolbar for the desired text formats from the configuration page: '/admin/config/content/formats'.

Technical details

Users should be embedding entities using the CKEditor WYSIWYG button as described above. This section is more techincal about the HTML markup that is used to embed the actual entity.

Embed by UUID (recommended):

<div data-entity-type="node" data-entity-uuid="07bf3a2e-1941-4a44-9b02-2d1d7a41ec0e" data-view-mode="teaser" />

Embed by ID (not recommended):

<div data-entity-type="node" data-entity-id="1" data-view-mode="teaser" />

Display Plugins

<div data-entity-type="node" data-entity-id="1" data-entity-embed-display="entity_reference:entity_reference_entity_view" data-entity-embed-settings='{"view_mode":"teaser"}' />

A more advanced use for embedding entities uses an entity embed display plugin, provided in the data-entity-embed-display attribute. By default we provide four different display plugins out of the box:

• default: Renders the entity using entity_view().
• entity_reference:formatter_id: Renders the entity using a specific Entity Reference field formatter. For example, entity_reference:entity_reference_label renders the entity using the "Label" formatter.
• file:formatter_id: Renders the entity using a specific File field formatter. This will only work if the entity is a file entity type.
• image:formatter_id: Renders the entity using a specific Image field formatter. This will only work if the entity is a file entity type, and the file is an image.

Configuration for the display plugin can be provided by using a data-entity-embed-settings attribute, which contains a JSON-encoded array value. Note that care must be used to use single quotes around the attribute value since JSON-encoded arrays typically contain double quotes.

The above example renders the entity using the entity_reference_entity_view formatter from the Entity Reference module, using the teaser view mode.
