Question

我一般来说对Python＆Flask还是相当陌生，但是我遇到了一个复选框无法解决的问题。数据库字段是一个整数（SQLite）。创建记录时，它可以使用1或0。但是，当我尝试使用WTForms编辑记录时，无法获得反映数据库中内容的复选框-1或0（选中或未选中）。下面有问题的字段是manager，dept_head和admin。不确定我缺少什么？任何建议将不胜感激。

道歉，但我想确保我没有遗漏任何东西。

型号

class User(UserMixin, db.Model):

__tablename__ = 'users'

id              = db.Column(db.Integer, primary_key=True)
firstname       = db.Column(db.String(128), nullable=False)
lastname        = db.Column(db.String(128), nullable=False)
email           = db.Column(db.String(128), nullable=False)
password_hash   = db.Column(db.String(128), nullable=True)
locationid      = db.Column(db.Integer, db.ForeignKey('locations.id'), nullable=True)
location        = db.relationship('Location', backref='users')
departmentid    = db.Column(db.Integer, db.ForeignKey('departments.id'), nullable=True)
department      = db.relationship('Department', backref='users')
job_title       = db.Column(db.String(128), nullable=True)
mobile_phone    = db.Column(db.String(16), nullable=False)
manager         = db.Column(db.Integer, nullable=False, default=0)
dept_head       = db.Column(db.Integer, nullable=False, default=0)
admin           = db.Column(db.Integer, nullable=False, default=0)
date_created    = db.Column(db.DateTime, default=db.func.current_timestamp())
date_updated    = db.Column(db.DateTime, default=db.func.current_timestamp(), onupdate=db.func.current_timestamp())
date_deleted    = db.Column(db.DateTime)

    self.locationid.choices = [(l.id, l.name) for l in Location.query.all()]
    self.departmentid.choices = [(d.id, d.name) for d in Department.query.all()]
