Cannot complete Flask-Migration

Question

I\'ve setup a local Postgres DB with SQLAlchemy and cannot commit my first entry. I keep on getting this error...

ProgrammingError: (ProgrammingError) relation          


        

Answer 1

Assuming that you have checked that the database exists using psql or pgAdmin, this error usually means exactly what it says. That can be due to either:

• not connecting to the correct database instance (check your db url: host/port and db name)
• not correctly configuring SQLAlchemy (see: SQLAlchemy create_all() does not create tables)
