In a previous article we explained the syntax used to write Drupal migrations. When migrating into content entities, these define several properties that can be included in the process section to populate their values. For example, when importing nodes you can specify the title, publication status, creation date, etc. In the case of users, you can set the username, password, timezone, etc. Finding out which properties are available for an entity might require some Drupal development knowledge. To make the process easier, in today’s article we are presenting a reference of properties available in content entities provided by Drupal core and some contributed modules.

For each entity we will present: the module that provides it, the class that defines it, and the available properties. For each property we will list its name, field type, a description, and a note if the field allows unlimited values (i.e. it has an unlimited cardinality). The list of properties available for a content entity depend on many factors. For example, if the entity is revisionable (e.g. revision_default), translatable (e.g. langcode), or both (e.g. revision_translation_affected). The modules that are enabled on the site can also affect the available properties. For instance, if the “Workspaces” module is installed, it will add a workspace property to many content entities. This reference assumes that Drupal was installed using the standard installation profile and all modules that provide content entities are enabled.

It is worth noting that entity properties are divided in two categories: base field definitions and field storage configurations. Base field configurations will always be available for the entity. On the other hand, the presence of field storage configurations will depend on various factors. For one, they can only be added to fieldable entities. Attaching the fields to the entity can be done manually by the user, by a module, or by an installation profile. Again, this reference assumes that Drupal was installed using the standard installation profile. Among other things, it adds a user_picture image field to the user entity and body, comment, field_image, and field_tags fields to the node entity. For entities that can have multiple bundles, not all properties provided by the field storage configurations will be available in all bundles. For example, with the standard installation profile all content types will have a body field associated with it, but only the article content type has the field_image, and field_tags fields. If subfields are available for the field type, you can migrate into them.

Available properties for other content entities

This reference includes all core content entities and some provided by contributed modules. The next article will include a reference for Drupal Commerce content entities. That being said, it would be impractical to cover all contributed modules. To get a list of yourself for other content entities, load the entity_type.manager service and call its getFieldStorageDefinitions() method passing the machine name of the entity as a parameter. Although this reference only covers content entities, the same process can be used for configuration entities.

What did you learn in today’s article? Did you know that there were so many entity properties in Drupal core? Were you aware that the list of available properties depend on factors like if the entity is fieldable, translatable, and revisionable? Did you know how to find properties for content entities from contributed modules? Please share your answers in the comments. Also, we would be grateful if you shared this article with your friends and colleagues.
