问题
I need to create a User class that allows for both record-level security as well as vertex properties, but OUser already extends OIdentity.
I'm also wondering if there's a way to get rid of the automatically generated admin user, as it seems redundant that I can connect to my database using the root user defined in the orientdb-server-config.xml, and I don't need that user (at least right now).
回答1:
You can let OIdentity to extend V:
alter class OIdentity superclass V
So now OUser and ORole are Vertices.
About "admin" you could also drop it if you always use the server's root user (That is God)
