I have the following abstract base class 

class DefaultInfo(models.Model):
  created_by = models.ForeignKey(User)
  modified_by = models.FroreignKey(User)

  class Meta:
    abstract = True

and a bunch of models using this class as their base.

When creating a graph I want to exclude the ForeignKey fields from DefaultInfo, otherwise the graph becomes really unreadable due to the relations to the User object. Note that there are some models that add an extra relation to the User model, so completely ignoring the User model isn't an option.

To get a more readable graph I've made a trivial change in

Disabling all relations defined in abstract fields sounds a bit rude. Is there a recommended way to ignore specific relations?
