That made difference, i think i got it working. I made a little
example for study purposes. From test part you see i can fetch
meaningful information with Country, CountryLanguage and Language
objects. Country has many CountryLanguages (having Language object and
is_primary field),
Next design problem for me is version table. I have Document model
with DocumentVersion model, but i dont know how to:
- get the latest version of document
- set creator and updator, automatic behavior for this
- update version number
- fetch thru Document(s) and DocumentVersion(s)
Lets see the

I just started experimenting with .4 last night, and I'm really
jazzed. The tutorials have been helpful, but I'm struggling to figure
out how to bridge the gap between the tutorial fragments and a real-
world application.
So far, I've got a little idea working, and I'm hoping to get some

It is a decorator I use on mapped classes constructors. It allows me

Ok, I've figured out the problem but not really sure what the proper
solution is.
Basically, I have Thing objects that can have attributes associated
with them. I have other classes that are subclasses of the Thing
object. These classes can provide more specific functionality based
on the type

So, the code I posted is a much simplified version of what I'm trying
to accomplish only used to illustrate the error I was getting. What I
actually want to do is select the appropriate class based on any
