Re: [Sqlalchemy-users] Strange Problem with missing values

[Michael Bayer]

well from a dependency point of view these two dumps are identical, so its not a bad dependency sort (whew). In the bad version, you have two separate instances of a Timesheet object (those numbers in the parenthesis are the Python id() of the object).  Id make a random guess that one of them is missing the data it needs. You might want to try to track down which one of those is which, see why theres two getting created.   if your program is simple enough, you might be able to put a module level variable "THIS" which the first Timesheet sets itself to, or if its not None raises an exception.  that way the second Timesheet will raise an exception and you can see a stack trace where its being created.
