Yeah, new api is great,
eg:
loader_fn = self.lazy_loader_map.get(relation_attribute.prop.lazy,
'selectinload')
self.opts.append(loader_fn(relation_attribute.and_(*relation_filter).options(*related.opts))
or with_loader_criteria and events you mentioned.
Thanks again. Have a nice weekend.
great, glad you were able to work that out that's a lot of new API to learn

Thank you very much,
It helped me a lot, UserDefinedOption and do_orm_execute, I missed it in
the documentation
P.S. Thank you for sqlalchemy, it's really helpful and thanks to nested
options it's really fun to use.

this is true, the parameters can't be known to be passed along to a secondary
query. the approach here would require that you make careful use of custom
user options and events in order to make it work. the general event hook you
would use is documented at
Sorry, once again :)
class X(Base):
id: int = Column('x_id', Integer, primary_key=True, autoincrement=True)
a_id: int = Column('a_id', Integer, ForeignKey('a.a_id'))
a = relationship(A)
s = select(A).where(A.id == 1)
s = s.options(joinedload(A.b_filtered_rel))
or
s =
Hello Mike,
Thank you very much for your response.
I ended up with that, but i wanna ask you about this solution.
class A(Base):
id: int = Column('a_id', Integer, primary_key=True, autoincrement=True)
#descr
class B(Base):
id: int = Column('b_id', Integer, primary_key=True,
yes, you would use bindparam("some_name") in conjunction with the "and_()"
feature, like options(selectinload(MyClass.foo.and_(MyClass.name ==
bindparam("some_name"

Hello,
is it possible in sqlalchemy arguments from db.execute(query, args) to be
passed to query emitted by selectinload?
Thanks,
