The error message is quite explanatory:
class FamilyLink(models.Model):
from_legacy = models.ForeignKey(Legacy, related_name = 'familylink_from_legacy')
to_legacy = models.ForeignKey(Legacy, related_name = 'familylink_to_legacy')
By default, if no related_name
attribute is set, the relatedname is set to familylink_set
and since 2 different fields from the same relation, it causes the issues.
