一百三十三：CMS系统之版块管理一

把模型创建到公共的models里面

class BoardModel(db.Model):
    __tablename__ = 'board'
    id = db.Column(db.Integer, primary_key=True, autoincrement=True)
    name = db.Column(db.String(20), nullable=False, comment='板块名')
    create_time = db.Column(db.DateTime, default=datetime.now)

manager中导入

执行数据库迁移

python manager.py db migrate
python manager.py db upgrade

form

class AddBoardForm(BaseForm):
    """ 添加板块 """
    name = StringField(validators=[InputRequired(message='请输入板块名称')])

class UpdateBoardForm(AddBoardForm):
    """ 修改板块 """
    board_id = IntegerField(validators=[InputRequired(message='请输入板块id')])
