Drupal 7 field instances source from database.

If the Drupal 7 Title module is enabled, the fields it provides are not migrated. The values of those fields will be migrated to the base fields they were replacing.

Available configuration keys:

  • entity_type: (optional) The entity type (machine name) to filter field instances retrieved from the source. If omitted, all field instances are retrieved.
  • bundle: (optional) The bundle machine name to filter field instances retrieved from the source. It should be used in combination with entity_type property and will be ignored otherwise.

Examples:


source:
  plugin: d7_field_instance
  entity_type: node

In this example field instances of node entity type are retrieved from the source database.


source:
  plugin: d7_field_instance
  entity_type: node
  bundle: page

In this example field instances of page content type are retrieved from the source database.

For additional configuration keys, refer to the parent classes.
