field

问题 I am pretty new to python and sqlalchemy and would like to ask for an advice. What would be the best way to force uppercase values in a SqlAlchemy field when the record is inserted/updated? Should I use events for that? Here I am using flask-sqlalchemy version, but I believe it is something similar to SQLAlchemy. from flask.ext.sqlalchemy import SQLAlchemy db = SQLAlchemy() class Item(db.Model): # I need to ensure the code column converts values to uppercase automatically code = db.Column(db

问题 I have this model: class Invoice(models.Model): owner = models.ForeignKey(settings.AUTH_USER_MODEL) data = models.TextField(default=None, blank=True, null=True) number = models.PositiveIntegerField(default=0, null=False) What I need is to auto-increment the field number for each separated user. The rationale is that each user has a list of Invoice , starting from number=1 to number=latest.number+1 . I do known about F() expressions, but can't figure out how to reference the latest/greatest
