I've an application that's been happily running for a few years, that does this:
class Person(Model):
# everyone's a Person
class Researcher(Model):
# a Researcher is Person who publishes research
person = models.OneToOneField(Person)
class Publication(Model):
author = models.ForeignKey(Researcher)
But this is no longer enough: now I also need to distinguish between
Researchers who are research students and members of staff. Those who are
students will need new fields such as "thesis_title" and "supervisors".
But, I will *still* need the Researcher class independently of the new
ResearchStudent and ResearchStaff classes, because it's needed for
Publication.author.
So now it might look something like this:
class Person(Model):
# everyone's a Person
class Researcher(Model):
# a Researcher is Person who publishes research
person = models.OneToOneField(Person)
class ResearchStaff(Model):
researcher = models.OneToOneField(Researcher)
class ResearchStudent(Model):
researcher = models.OneToOneField(Researcher)
supervisors = models.ManyToManyField(ResearchStaff)
class Publication(Model):
author = models.ForeignKey(Researcher)
How manageable is this going to be? Is there a better way of doing what I need
to do, perhaps through inheritance?
Thanks,
Daniele
