how to get specific columns in flask-sqlalchemy code example
Example: flask sqlalchemy query specific columns
## You can use the with_entities() method to restrict which columns you'd like to return in the result. (documentation)
result = SomeModel.query.with_entities(SomeModel.col1, SomeModel.col2)
## Depending on your requirements, you may also find deferreds useful. They allow you to return the full object but restrict the columns that come over the wire.
