I've discovered if I use an object (found by session.query) as the value
for the relationship field, I get the issue of having objects being added

But if I insert, for the relationship, the id of the register in database

Hi.
I'm dealing with a weid situation:
My 'session' is loaded with objects, and when I commit all the objects are

It's a problem to me because I'm creating a lot of objects and return it as

You're experiencing exactly what Michael pointed you to.
Person has a relationship+backref to SourceDatabase though
`Person.source_database`. When you create a `John` and assign the existing
source_database, sqlalchemy is implicitly adding the Person so that the

Ok. Here's a code as an example of my situation:
First, the file ormdb.py:
db =
create_engine('mysql+mysqlconnector://root:password@localhost/debug',paramstyle='format')

Seems that sqlalchemy is executing add() method in background...

Hello,
I have a very simple data model with a one to many relationship - a thread
could have many identifiers that link to it:
class Thread(Base):
__tablename__ = 'threads'
id = Column(Integer, primary_key=True)
link = Column(String(length=512, collation=UTF8),
