This is a side-by-side JHipster 7 blue print showing how to put human-readable foreign key field in place of UUIDs into the user interface where entities have relationships with other entities.
This code was generated using the JHipster blueprint "generator-jhipster-multiple-human-readable-foreign-key-fields". The JDL can be modified and the @customAnnotation("DISPLAY_IN_GUI_RELATIONSHIP_LINK") can be used with any fields of an entity which would make it easier to identify that entity when displayed (as part of a relationship).
