[SQLObject] Validators and Pickle Columns

[Tom C. <su...@ic...>]

Hi all,

I would like to use a validator with a PickleCol like this:

---------------- cut ---------------------------------------------------------
from formencode import validators

class PTValidator(validators.FancyValidator):

    def validate_python(self, value, state):
        # Do validation on value here before storing it in the db
        print "value:", value


class PT(SQLObject):
    pickled = PickleCol(validator=PTValidator)

---------------- cut ---------------------------------------------------------

The problem is that (it seems) value is already pickled by the time it is 
passed to the PTValidator.validate_pyton() method.

Can anyone give me some example/advise on how to use validators on a pickle 
column and being able to **validate** the value being stored only, but still 
leaving SQLObject to deal with the pickling/unpickling?


Thanks,
 Tom
