[SQLObject] date time column default now()

[Brian R. <br...@se...>]

I need help using SQLObject. I am trying to override a column attribute 
without actually sending an argument.

Is there a way I can get a time stamp functionality out of my date time 
column default?

...
from mx.DateTime import *
class table(SQLObject):
	timestamp = DateTimeCol(default=now())
...

The problem I am having is that the stamp fills in at the time when the 
object was initialized, not when a new row is added.  This is the 
expected behavior.

I was thinking the fix was adding something like:

...
	def _set_timestamp(self):
		return now()
...

but, I get: "_set_timestamp() takes exactly 1 argument (2 given)"


After removing the default, I also tried:

...
    def _set_timestamp(self):
       self._SO_set_timestamp(now())
...

but, I get: "did not get expected keyword argument 'timestamp'"

I see in the manual where I can pass a value to these and then do 
something with this value. However, I would much rather not pass 
anything and get a time stamp in each row, once when created and maybe 
in a separate field once when updated. Any help, much appreciated.
