   Where?! I do not see this in the code!

   Isn't Col(default=my_value) what you want?

   Again, I do not understand (probably a difference in terms). Let me try
to guess what you mean.

class MyTable(SQLObject):
   name = StringCol(length=255)

row = MyTable() # error - the call lacks required column "name"

   Is it what you mean? If I guessed it right, if_empty in validators would
not help you - the error is triggered in SQLObject._create(), no validators
have been triggered yet.
