我有用户表:
class User(db.Model):
__tablename__ = "users"
UserID = db.Column(db.Integer, primary_key=True, autoincrement=True)
FirstName = db.Column(db.String(255), nullable=False)
# relationships
Emails = db.relationship('Email', backref='user', lazy='dynamic')
使用电子邮件表:
class Email(db.Model):
__tablename__ = "user_emails"
Email = db.Column(db.String(255), unique=True, primary_key=True, nullable=False)
UserID = db.Column(db.Integer, db.ForeignKey('users.UserID'), nullable=False)
如何根据电子邮件过滤或查找用户?
我在下面试过,但它不起作用:
DBModel.query.filter(DBModel.Emails.any(Email=searchInput))
DBModel.query.filter_by(Emails=searchInput).first()
答案 0 :(得分:0)
我用这个来解决:
DBModel.query.join(DBModel.Emails).filter_by(Email=id).first()
