SQLAlchemy JSON as blob/text

Question

I\'m storing JSON down as blob/text in a column using MySQL. Is there a simple way to convert this into a dict using python/SQLAlchemy?

Answer 1

This is what I came up with based on the two answers above.

import json

class JsonType(types.TypeDecorator):    

    impl = types.Unicode

    def process_bind_param(self, value, dialect):
        if value :
            return unicode(json.dumps(value))
        else:
            return {}

    def process_result_value(self, value, dialect):
        if value:
            return json.loads(value)
        else:
            return {}
