Raised when trying to access the related manager of a foreign key pointing from a normal model to a translated model using the standard manager instead of one returned by
hvad.utils.get_translation_aware_manager(). Used to give developers an easier to understand exception than a
django.core.exceptions.FieldError. This exception is raised by the
hvad.utils.SmartGetFieldByNamewhich gets patched onto the options (meta) of translated models.
