Re: How to store a key to a something that can be either a person or an organization?

You can use Generic Key: https://docs.djangoproject.com/en/1.11/ref/contrib/contenttypes/

Hello,

Two real examples that I've faced:

    class MeteorologicalStation(models.Model):
        ...
        owner = models.ForeignKey(to a person or organization)


    class Document(models.Model):
        ...
        authors = models.ManyToManyKey(to persons or organizations)

What I do is I create a superclass that I call Lentity (short for "legal
entity", despite the fact that it could refer to a group of people and is not
necessary legal) and the two subclasses Person and Organization, with
multi-table inheritance.

But since I guess that this is a relatively common problem, I was wondering
about what other people are doing.

Thanks!

Antonis
