> Hi Marc,

> if I remember correctly (can't check now), the documentation clearly states that you should avoid using null=True on CharField unless you have a good reason. Your example is a textbook reason why is it recommended - having two distinct states for "empty string" (i.e. "blank" and "null") leads to inconsistencies and confusion.
