Hello,
With the following custom type:
class JSONEncodedDict(types.TypeDecorator):
""" Represents an immutable structure as a JSON-encoded string. """
impl = types.TEXT
def process_bind_param(self, value, dialect):
return json.dumps(value) if value is not None else None
def process_result_value(self, value, dialect):
return json.loads(value) if value is not None else None
is there a method to override to automatically transform instances of
this class when they're used in a SQL expression (for example an
myquery.order_by(col), where col is an instance of JSONEncodedDict)?
Thank you!
Julien
