Say I have a Content type of Fruit. I have an Entity Reference on the User Profile to Fruit nodes. I want to create a view that shows all Fruit nodes that are NOT referenced by the Entity Reference on the current user profile.
(More details: I can create a view that includes Fruit nodes on the current user profile, by creating a view of Fruit nodes with a Relationship to the Entity Reference on the User Profile. Alternatively, by creating a View of users, filtering by current users, and then using the entity reference to show the data from the Fruit nodes. However, I haven't found a way to create a view of Fruit nodes that are NOT referenced on the current User Profile.
