Access other columns in a custom type

[Hussein Samadi]

Hi everyone.

I'm creating a new SQLA custom type using TypeDecorator base class. Is it possible to have access to the value of other fields in "process_result_value" method? Generally, is it possible to create a custom type that have access to other column's data in the de-serialization process?

Thank you

not at all, you would need to approach your problem at a different level.

Thank you
