def alias(altAttrName: String): Self

Alias to non-compatible attribute name like type or first-name etc.

Alias to non-compatible attribute name like type or first-name etc.

Molecule then creates an alias to the special name in the schema so that queries will match both the attribute name and the alias.

Concrete fields

lazy val owner: Self

Owner option.

Owner option.

This entity owns the referenced entity/entities.

  • If this entity is deleted, its references are deleted too (and recursively if sub entities have owned entities!)



Specifies that an attribute whose type is :db.type/ref is a component.

Referenced entities become subcomponents of the entity to which the attribute is applied.

When you retract an entity with :db/retractEntity, all subcomponents are also retracted.

When you get the graph of an entity, all its subcomponent entities are fetched recursively.

lazy val index: Self

Index option (defaults to true).

Generated index for this attribute. By default all attributes are set with the indexed option automatically by Molecule, so you don't need to set this.

lazy val uniqueIdentity: Self

Unique identity option.

Attribute value is unique to each entity and "upsert" is enabled.

Attempts to insert a duplicate value for a temporary entity id will cause all attributes associated with that temporary id to be merged with the entity already in the database.
