Hi all,
I have been using sqlalchemy for my projects, recently I came across a
situation where my id(BigInteger) has over flown, I use postgres,
I know in postgres I can reset my autoincrement using this query: 'ALTER
SEQUENCE tablename_id_seq RESTART WITH 1',
is there anything like this in
One more doubt is, is there a way to filter on the full json
something like this:
in your example only:
print(Session.query(Student).filter(Student.data_test
=={'foo':'bar'}).first())

Hi,
I tried using direct plain JSON:
my model
class Student(db.Model):
__tablename__= 'students'
id=db.Column(db.Integer, primary_key=True,autoincrement=True)
name=db.Column(db.String(200))
roll_no=db.Column(db.Integer)
data_test=db.Column(db.JSON)
I tried this:
*a =
Hi Mike,
as you said I tried this:
*from sqlalchemy.dialects import postgresql class Student(db.Model): #
...data_test=db.Column(postgresql.JSON) *
and I tried querying like this:
*a = Student.query.filter(Student.data_test["foo"].astext =="bar").first()*
tried this as well:
*a =
Hi,
I am using flask-sqlalchemy in my project, but I am not able to understand
how to query(filter_by) on a json column

'postgresql://postgres:postgres@localhost:5432/test_db'

Thanks Mike for suggestions, was able to solve both the issues with slight
changes in the db models
added lazy='dynamic' on both sides where back_populates is being used

Yes Mike will do that, mostly its marshmallow model schema which is
creating the object, as I am using Flask + marshmallow for APIs,
apart from that I have another issue, which i am not able to uderstand:
I have a many-to-many relationship between 2 models, same as posted above,
still ill put
A package object is getting created, and its inserting it into database,
have to debug why is it inserting into db
Somehow i got it working, added: db.session.rollback(), before append
statement
Dont know whether its the right approach
Thanks
