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!
