Hi,
As this is my first post I'd like to thank you for your work on this
project.
Originally I posted this following question to pgsql-gui-dev and was
advised to repost here.
I have a question regarding modifying configuration db model for pgadmin4:
When trying to create a new migration file I get an error:
sqlalchemy.exc.NoSuchTableError: user_old
The command used: FLASK_APP=pgAdmin4.py flask db migrate -m "Add data
groups"
The db is initialized with: python setup.py, I also tried:
FLASK_APP=pgAdmin4.py flask db init
When commenting out (just for tests) content of
"web/migrations/versions/35f29b1701bd_.py" I get a similar error but with
"server_old".
So my question is what is the correct procedure to modify configuration db
or how to solve the mentioned issue?
Thanks in advance,

name = db.Column(db.String(128), nullable=False)
__table_args__ = (db.UniqueConstraint('user_id', 'name'),)
