I'm using Flask SqlAlchemy. I'm inserting data into a Postgres DB and there is a JSON column type. When there is no data, I return None with the intention that that will set NULL into the column. This is what's suggested

CodePudding user response：

What you describe is the default behavior.

The JSON and JSONB column type can be initialized with the parameter none_as_null set to True. This parameter is by default False.

The documentation for reference.
