some suggestions from available tickets could be sorted out and another approach could be simpler new API for relationFields/ReverseRelation/ForwardRelation/RemoteRelation etc

| In order to fix these design limitations and inconsistancies, the proposed | ||
| solution is to refactor Fields/RelationFields to new simpler API and | ||
| incorporate virtualField type based refctors of RelationFields. |

yes you r right. I have to adjust the dep based on master
|
I wonder if it is worth taking into account what something like django-polymorphic needs? (I'm not myself qualified to say what that might be). |
|
i think django-polymorphic should be improved by the changes if done correctly |
This is a very early WIP draft. I am still working on figuring out some issues and proper approaches.
I will share it on mailing list soon after I think it's ready for initial review. Any improvement suggestions are highly welcome.
