Is it possible to join model types in Django into one object?

Question

For example I have two model objects, Person and Address. Address has a reference to a Person id. What would a query look like that pulls them out together as one object, or is that not possible to do with Django?

Answer 1

I'm not exactly sure what you're trying to ask, but I'll give it a shot.

I'm gonna assume that your models look something like:

class Person(models.Model)
    first_name = models.CharField()
    last_name = models.CharField()

class Address(models.Model)
    person = models.ForeignKey(Person)
    street = models.CharField()
    city = models.CharField()
    state = models.CharField()

Now, get an address:

address = Address.objects.get(id=address_id)

Then you can reference the person like so:

address.person.first_name

Answer 2

Have a read of the Django docs on related objects. Going from a Person to related Addresses is equivalent to going from a Blog to its related Entries in the examples.

If you have a person, you can do person.address_set.all() to get all addresses for that person.

If each person has only one address, use a OneToOneField, and then you can use person.address to get the address.
