Re: [SQLObject] pickling an SQLObject?

Just the id is needed.
tried that. seems to work for me:
    def __getstate__(self):
        return self.id
    def __setstate__(self,id):
        a=self.get(id)
        self.__dict__=a.__dict__

Only the id is needed.
I don't like the way the object is copied (transfered should I say?). Do you think there is a smarter solution?
I tried this. seem to work fine

>>> a=Users.get(1)
>>> import cPickle
>>> b=cPickle.dumps(a)
>>> c=cPickle.loads(b)
>>> c
<Users 1 login='asdf' password='asdfasdf' email="'[EMAIL PROTECTED]'" validated=True validationString='0sdr8z6kfj'>
>>> c.password='qwerqwer'
>>> a
<Users 1 login='asdf' password='qwerqwer' email="'[EMAIL PROTECTED]'" validated=True validationString='0sdr8z6kfj'>
>>>

Would it be wise to store only the table and id? (and do an update when 
storing)
During load, the object would be retrieved back from the database.


   The table is already there, in sqlmeta. You need id and a connection. I
am not sure about transactions...
