I'm trying to filter a JSONB column in flask-sqlalchemy and am having trouble:
class Journal(db.Model):
id = db.Column(db.Integer, primary_key=True)
synonyms = db.Column(JSONB)
j = Journal(synonyms=['red', 'blue'])
db.session.add(j)
db.session.commit()
records = Journal.query.filter(Journal.synonyms.contains('red')).all()
I get the error: sqlalchemy.exc.InternalError: (psycopg2.errors.InFailedSqlTransaction) current transaction is aborted, commands ignored until end of transaction block
Any idea what I am doing wrong?
I figured out the correct query for this. It is:
import json
records = Journal.query.filter(Journal.synonyms.contains(json.dumps('red'))).all()
