posts = PostsModel.find_by_id_list(id_list=post_id_list)
I'm just wondering, if there is an easy way to get the post object from the
query instead of doing the above.

Hi there,
I really have no idea how to do this via sqlalchemy. I have 2 tables:
class NodesModel(db.Model):
__tablename__ = 'nodes'
id = db.Column(db.BigInteger, primary_key=True)
topic = db.Column(db.String(20), nullable=False)
pn = relationship("PNModel", backref="nodes")
Hi All,
I have a question which I think I know the answer to but I'd like to
confirm.
I have a table/model that when I return the objects or list of objects, I
want all the columns (15 of them) to be returned except 2. Is there a way
to do that? Currently, I'm doing this (as per documentation)

the same thing?
2. Why do we not use the foreign_keys method to link all the tables
instead of backref in the parent table?
Thanks.

I've also tried using

Hi there,
I'm been puzzling over this and still can't find answer.
I have 2 tables:
Nodes:

project_uuid = db.Column(UUID(as_uuid=True),
db.ForeignKey('projects.uuid'))

As told by Jonathan, I’m trying to create a separate package for the models.
Can anyone point me in the right direction to create the models as a module. I
can’t seem to think how to do it because of the different ways you can connect
to the database and there is the unit test to do. I just
Thanks Jonathan. Exactly what I wanted to know.

Hi there,
I'm just wondering what is the best way to do this. I'm not asking about
micro-services, just a general API coding practice.
Currently, I have a number of APIs (separate code base) and each has their
own model (e.g. users) and the endpoints create don't need anymore tables
(models)
