[sqlalchemy] Infinite recursion trying to deserialize any restriction
Hi everyone! I have a simple one-to-many relation between two classes, and I'm trying to serialize/deserialize an any restriction on them.. My problem is that deserialization fails with maximum recursion depth exceeded. Am I doing something wrong? Here's my testcase: from sqlalchemy import Column, Integer, String, ForeignKey from sqlalchemy.ext import serializer from sqlalchemy.orm import relation from sqlalchemy.ext.declarative import declarative_base # Tables definition Base = declarative_base() class Child(Base): __tablename__ = 'child' id = Column(Integer, primary_key=True) parent_id = Column(Integer, ForeignKey(parent.id)) data = Column(String) class Parent(Base): __tablename__ = 'parent' id = Column(Integer, primary_key=True) children = relation(Child) # Build any restriction r = Parent.children.any(Child.data==x) # Serialize and deserialize it ser = serializer.dumps(r) serializer.loads(ser, Base.metadata) Thanks for your time!

[sqlalchemy] Re: A question about best practices after the Object Relational Tutorial
I have written a descriptor for implementing hashed storage of passwords. I added some documentation and added it to the wiki as a recipe: http://www.sqlalchemy.org/trac/wiki/UsageRecipes/HashProperty It doesn't depend on anything in SQLAlchemy and works with any object persistence framework. It could probably use some better null handling and error reporting, but should be usable as is.

[sqlalchemy] Specifying descending order_by on a backref
I'm using the declarative extension. When I specify a backref on a relation, I see the order_by argument and I'm pointing it to the column object. That works, but I need to sort the backref descendingly, not ascendingly. I don't see an option for that in the Relation()/backref() arguments. What am I missing?

[sqlalchemy] Re: Auto-loading With Relationships
According to Autocode's readme it doesn't support relationships. The major reason that Soup won't work for me is it doesn't support relationships between tables. I'm still going to take a closer look at Autocode. Thanks for the suggestion. -Paul On Feb 17, 4:09 pm, Michael Trier mtr...@gmail.com wrote: Hi, On Tue, Feb 17, 2009 at 2:50 PM, Gp gpm...@gmail.com wrote: We have sets of databases with several hundred tables per database.
