[Schevo-devel] Schema questions

[Tom Locke]

Hi,

This wheel is really gonna squeak! If there's docs for this stuff, I 
apologise - please point me at them.

What does this mean:

  matrix = f.entity(('Matrix', CASCADE))

Something to do with cascaded deletes?

-----------

What does allow_create = False do on an enitity field decl?

----------

I've got a Person and a PhoneNumber, where the PhoneNumber references a 
Person.

Is there a more concise way to get the phone numbers for a person than:

    p.sys.links("PhoneNumber", "person")

(p is a Person)

----------

In the identity schema, I see methods defined like x_methodname, and 
accessed as obj.x.methodname right? Can you explain what that's all 
about. It means the method automatically runs in its own transaction?

---

Does schevo have nested transactions?

Thanks

Tom
