（1）apps/models

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

（2）manage.py

from apps.models import BoardModel

生成数据库表

python manage.py db migrate
 
python manage.py db upgrade

（3）cms/forms.py

class AddBoardsForm(BaseForm):
    name=StringField(validators=[InputRequired(message='请输入版块名称'),Length(2,15,message='长度应在2-15个字符之间')])
 
class UpdateBoardForm(AddBoardsForm):
    board_id=IntegerField(validators=[InputRequired(message='请输入版块名称')])

        event.preventDefault();
        zlalert.alertOneInput({
            'title':'添加板块',
