The generator contains a function
field_from_path
that accepts a root type and a path. This was originally written before I supported fragments, so assumed that the root type would always be an object (as it is for query, mutation & subscription roots). For fragments though the root type can also be an interface or a union type.This partially fixes the problem so that we support interfaces. I didn't add support for unions because unions don't specifically have fields (except
__typename
) and I can't remember how this stuff works well enough to fix it for unions right now.Suspect there might be other problems related to this in there, but that's a problem for another day.
Fixes #993
