I am working on my localization stuff and run into a problem when I want
to add an relationship to a class.
I based my code on
http://www.sqlalchemy.org/trac/wiki/UsageRecipes/Views , but maybe I
messed something up.
The following works:
r1 = session.query(db.Region_LV).get(175)
print
For a deferred() itself, we don't have an option that does this.Though this
is an unusual request. If you definitely want the deferreds to load, what's
the issue having them render inline into the original query ?The advantage
to subqueryload is primarily in that it loads multiple

The following gives CircularDependencyError
where I think there isn't, but you know I don't know that much the internals
of SQLAlchemy and maybe (and it is a strong possibility) I'm wrong. I've
ripped of the classes causing the error (copy/paste will re-produce the
error).

I forgot to say thank you, I've solved it as you suggested and created a

What is the right way to use .order_by() to order by the values returned
by a model object property? My model object is like this:
class Project(DeclarativeBase):
__tablename__ = 'project'
id = Column(Integer, primary_key=True)
...
@property
def remainderDue(self):
You'd use a hybrid for this case, and due to the usage of float() you'd
probably want to produce a separate @expression that doesn't rely on a Python
function.
Docs and examples for hybrid are at
http://www.sqlalchemy.org/docs/orm/extensions/hybrid.html
Separate @expression:
Still getting the hang of SQLAlchemy terminology.
I didn't mean a simple deferred() column, but a deferred column_property()
which defines a scalar select(). Like in the example here

.
