parse_blob override in 2.19.01

[DenesL]

Hi all

a while back in this post https://groups.google.com/d/msg/web2py/v6bB7PHa7f8/aZjaIby1fTgJ this was said:

web2py uses b64encode/decode to store/retrieve data in blobs. Legacy tables probably do not do it.

You need you make your own custom adapter to override a method. For example for PostgreSQL:

from gluon.dal import ADAPTERS, UseDatabaseStoredFile,PostgreSQLAdapter
class MyPostgresAdapter(PostgreSQLAdapter):
     drivers = ('psycopg2',)
     def parse_blob(self, value, field_type): return value

ADAPTERS['mypostgres'] = MyPostgresAdapter

db = DAL('mypostgres://.....')

Is this still possible with web2py 2.19.01?

Thanks,

Denes
