builtins.TypeErrorSQLite时间类型仅接受Python时间对象作为输入

如何解决builtins.TypeErrorSQLite时间类型仅接受Python时间对象作为输入

我尝试使用Flask Login从HTML到sqlite输入时间

这是模特

class Shop(db.Model):
    __tablename__ = 'shop'
    id = db.Column(db.Integer,primary_key=True)
    shop_id = db.Column(db.BigInteger)
    shop_name = db.Column(db.String(50))
    shop_phone = db.Column(db.String(10))
    shop_email = db.Column(db.String(100))
    shop_calendarId = db.Column(db.String)
    shop_address = db.Column(db.String(300))
    shop_provinces = db.Column(db.String(20))
    shop_start_time = db.Column(db.Time)
    shop_end_time = db.Column(db.Time)
    shop_workers = db.Column(db.Integer)
    shop_slots = db.Column(db.Integer)
    shop_step_time = db.Column(db.Integer)
    shop_duration = db.Column(db.Integer)
    shop_web = db.Column(db.String)
    shop_fanpage = db.Column(db.String)
    shop_facebook_mes = db.Column(db.String)
    shop_logo = db.Column(db.String)
    shop_description = db.Column(db.String(300))
    shop_created_date = db.Column(db.Date)
    shop_ended_date = db.Column(db.Date)
    shop_token = db.Column(db.String)
    def __str__(self):
        return "{}".format(self.name)
    def __repr__(self):
        return "{}: {}".format(self.shop_id,self.__str__())

这是获取表格的python代码

@main.route('/dashboard',methods=['POST'])
@login_required
def dashboard_post():
    email = current_user.email
    shop = Shop.query.filter_by(shop_email=email).first()
    shop_workers = request.form.get('shop_workers')
    shop_slots = request.form.get('shop_slots')
    shop_step_time = request.form.get('shop_step_time')
    shop_duration = request.form.get('shop_duration')
    shop_provinces = request.form.get('shop_provinces')
    shop_address = request.form.get('shop_address')
    shop_phone = request.form.get('shop_phone')
    shop_token = request.form.get('shop_token')
    shop_name = request.form.get('shop_name')
    shop_start_time = request.form.get('shop_start_time')
    shop_end_time = request.form.get('shop_end_time')
    shop_web = request.form.get('shop_web')
    shop_fanpage = request.form.get('shop_fanpage')
    shop_facebook_mes = request.form.get('shop_facebook_mes')
    shop_logo = request.form.get('shop_logo')
    shop_description = request.form.get('shop_description')
    if shop_workers != '':
        shop.shop_workers = shop_workers
        db.session.commit()
    if shop_slots != '':
        shop.shop_slots = shop_slots
        db.session.commit()
    if shop_step_time != shop_step_time:
        shop.shop_step_time = shop_step_time
        db.session.commit()
    if shop_duration != '':
        shop.shop_duration = shop_duration
        db.session.commit()
    if shop_provinces !='':
        shop.shop_provinces = shop_provinces
        db.session.commit()
    if shop_phone !='':
        shop.shop_phone = shop_phone
        db.session.commit()
    if shop_address !='':
        shop.shop_address = shop_address
        db.session.commit()
    if shop_name !='':
        shop.shop_name = shop_name
        db.session.commit()
    if shop_address !='':
        shop.shop_address = shop_address
        db.session.commit()
    if shop_start_time !='':
        shop.shop_start_time = shop_start_time
        db.session.commit()
    if shop_end_time !='':
        shop.shop_end_time = shop_end_time
        db.session.commit()
    if shop_web !='':
        shop.shop_web = shop_web
        db.session.commit()
    if shop_fanpage !='':
        shop.shop_fanpage = shop_fanpage
        db.session.commit()
    if shop_facebook_mes !='':
        shop.shop_facebook_mes = shop_facebook_mes
        db.session.commit()
    if shop_logo !='':
        shop.shop_logo = shop_logo
        db.session.commit()
    if shop_description !='':
        shop.shop_description = shop_description
        db.session.commit()

    return redirect(url_for('main.dashboard_redirect'))

这是html代码

<div class="col"><label
                                            class="label-input-group">Giờ mở cửa: {{ shop_start_time }}</label>
                                        <div class=""><input id="shop_start_time" name="shop_start_time" type="Time"
                                                             class="next-input"
                                                             placeholder="{{ shop_start_time }}" step="1"
                                                             value="">
                                        </div>
                                    </div>
                                    <div class="col"><label
                                            class="label-input-group">Giờ đóng cửa: {{ shop_end_time }}</label>
                                        <div class=""><input id="shop_end_time" name="shop_end_time" type="Time"
                                                             class="next-input"
                                                             placeholder="{{ shop_end_time }}" step="1"
                                                             value="">
                                        </div>
                                    </div>

错误如下

sqlalchemy.exc.StatementError: (raised as a result of Query-invoked autoflush; consider using a session.no_autoflush block if this flush is occurring prematurely)
(builtins.TypeError) SQLite Time type only accepts Python time objects as input.
[SQL: UPDATE shop SET shop_start_time=? WHERE shop.id = ?]
[parameters: [{'shop_start_time': '08:00','shop_id_1': 1}]]

有人帮助我，谢谢

解决方法

引发异常是因为您试图将字符串“ 08:00”直接从输入字段传递给对象。

该对象希望您提供time对象，例如用datetime创建的对象。 More about python's time objects.。您可以使用datetime's strptime。如果要自动解析，请查看Flask wtf。

谢谢大家，我更改了代码，它成功了

  if shop_start_time !='':
        shop.shop_start_time = datetime.strptime(shop_start_time,"%H:%M").time()
        db.session.commit()
    if shop_end_time !='':
        shop.shop_end_time = datetime.strptime(shop_end_time,"%H:%M").time()
