I use the following column in my table: email = Column(String(60), unique=True) However, I need the possibility to save empty strings in this column. Namely, I need something like this: email = Column(String(60), unique=True, blank=True) but it doesn't work. Is it possible to implement this within SQLAlchemy? What is correspondent SQL (Postgresql dialect)? -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
