I apologize for the previous message being a bit rude. Python is a strongly typed language so the empty string is pretty different from None. null=True means you can leave a value to None blank=True means the user can leave a form field empty If you assign your charfield an empty string then it is not empty any longer. Might be easier to figure if you were using numbers were None might say you have no result and 0 that you have a result which is 0.
