I'm writing a package for Pyramid which has a base AuthUser

ability to extend the AuthUserProfile so that the Mako templates can

Currently, it

The issue I'm running into currently is that in the model
uid was the logged in user's id. I didn't grasp the bindparam/
eagerload dependency and almost had that solution working. That wiki
page clarified it.
As always, thank you for the quick response.

I'm trying to pass a value to a relation at runtime rather than
instantiation time. I've got the callable working with a fixed value,
but, in reading the docs over the last few days , I'm either not
finding the proper incantation or the right terms in the documentation
to figure out what I'm
By forcing my join, it appears that I can get it to do what I wanted.
After thinking a bit about the ORM, doing what I wanted 'magically'
would have been quite a feat.

I've tried to pull out as much cruft and redesign to get the bare
minimum model to make it easier to use the collection_class.
What I'm trying to do:
page.template.blocks[0].elements[0]
as
page.template['content'].elements[0]
Right now, I get:
page.template.blocks[0].name = 'content'
Renamed the association_proxy now that I understand how it works and
what I was doing wrong. I ended up with
model/cms.py:
class Template(Base):
__tablename__ = 'm_template'
id = Column(mysql.BIGINT(20, unsigned=True), primary_key=True,
autoincrement=True)
name =
meta.Session.query(Job).order_by(Job.min_level).order_by(Job.descr).filter(Job.tier==1).outerjoin((User_job_progress,
User_job_progress.job_id==Job.job_id)).filter(User_job_progress.fb_uid==1)
results in a query of:
FROM xxx_jobs LEFT OUTER JOIN xxx_user_job_progress ON
Just not having a lot of luck here. :)
meta.Session.query(Job).order_by(Job.min_level).order_by(Job.descr).filter(Job.tier==1).outerjoin((User_job_progress,
and_(User_job_progress.job_id==Job.job_id,
User_job_progress.fb_uid==1))).all()
results in:
SELECT xxx_jobs.job_id AS xxx_jobs_job_id,
% for job,progress in tmpl_context.jobs:
error on my part after the outerjoin.
Thanks for the pointers in the right direction.

I have 4 tables: users, jobs, job_items, job_progress
class User(Base):
__tablename__ = 'xxx_users'
fb_uid = Column(mysql.MSBigInteger(20, unsigned=True),

class Job(Base):

job_id = Column(mysql.MSBigInteger(20, unsigned = True),
That's what I thought about 10 minutes after posting. I thought there
might be a trick in the DeclarativeBase declaration that I missed.
Thanks for the quick reply.

I've run into a minor stumbling block.
My metadata table is set up as a relationship rather than
Base.metadata. Since I needed to expose sorttree which would attached
