Correct implementation of an interface

[Poolshark (Flo Ragossnig)]

So if I understand correctly my problem is a follow up of the original thread.

Hi @spinelsun, We added support to repeat the field names in implementing type and interface given that they are of same type and have same nullable condition. If field in interface have some directive then field in implementing type will inherit that directive.

And having same field name in multiple implementing interfaces is not allowed except ID type.This fix is currently avaliable in master branch and will also be avaliable in 20.11 release.

So field repetition is allowed but it causes different implementations to a case where we omit the fields. And this should simply NOT be the case! However the interpretation of Dgraph’s “valid GraphQL" schema is, the representation of it should not change with the way we write out the schema.

So either Dgraph should always automatically generate the predicates for the missing type

• Dog.name
• Cat.name and
• Ant.name

or there is only one predicate, Animal.name for all the types which implement the interface - even when repeating the fields.
