使用flask开发的一个web系统，后台用户管理采用的是点击目录后采用load方式不刷新动态加载
1、如图，点击“兖矿集团”，动态加载出右侧的页面

2、问题
为了实现添加用户表单（adduserform）的表单验证，我使用了wtform，效果如图
图片描述
这个表单的代码：

class AddUserForm(FlaskForm):
    username = StringField('用户名', validators=[DataRequired(message='用户名不能为空')])
    password = StringField('密码', validators=[DataRequired('用户密码不能为空！'), Length(min=4, message='密码位数要大于4位')])
    name = StringField('姓名', validators=[DataRequired('用户姓名不能为空！')])
    sex = SelectField(choices=[(1, '男'), (2, '女')], coerce=int)
    mobile = StringField('手机', validators=[DataRequired('用户手机不能为空！')])
    def validate_mobile(form, field):
        if not field.data.isnumeric():
            raise StopValidation('手机号只能输入数字')
        elif len(str(field.data)) != 11:
            raise StopValidation('手机号位数不正确')
    email = StringField('邮箱', validators=[DataRequired('用户邮箱不能为空！'), Email('邮箱格式错误！')])
    title = StringField('职衔', validators=[DataRequired('用户职衔不能为空！')])
    telephone = StringField('座机', validators=[DataRequired('用户座机不能为空！')])
    address = StringField('地址', validators=[DataRequired('用户地址不能为空！')])
    submit = SubmitField('登录')

adduser视图函数：

@app.route('/system/usermanage/adduser/<gid>/<cid>/<ccid>/<mid>/<ssid>', methods=['POST'])
@login_required
def adduser(gid, cid, ccid, mid, ssid):
    adduserform = general.AddUserForm(request.form)
    info = {}
    info['gid'] = gid
    info['cid'] = cid
    info['ccid'] = ccid
    info['mid'] = mid
    info['ssid'] = ssid
    print(adduserform.validate())
    if request.method == 'POST':
        if adduserform.validate_on_submit():
            formdatas = request.form
            print('formdatas',formdatas)
            password = generate_password_hash(formdatas['password'])
            username = formdatas['username'].strip()
            if general.SQL('''select username from users where username='{0}' '''.format(username)):
                info['type'] = 'warning'
                info['title'] = '错误'
                info['notice'] = '用户名：' + username + ' 已存在！'
                print('用户名：' + username + ' 已存在！')
                return render_template('notice.html', info=info)
                # flash('用户名：' + username + ' 已存在！')
                # errors['flash'] = '用户名：' + username + ' 已存在！'
            else:
                sql = '''insert into users (gid,cid,ccid,mid,ssid,username,password,type,name,sex,email,mobile,telephone,title,address)
                         values ({0},{1},{2},{3},{4},'{5}','{6}',{7},'{8}','{9}','{10}','{11}','{12}','{13}','{14}')'''.format(
                         gid,cid,ccid,mid,ssid,username,password,3,formdatas['name'],formdatas['sex'],formdatas['email'],
                         formdatas['mobile'],formdatas['title'],formdatas['telephone'],formdatas['address'])
                print(sql)
                try:
                    general.SQL(sql)
                    info['type'] = 'success'
                    info['title'] = '添加用户成功'
                    info['notice'] = '用户' + username + ' 已添加！'
                    print('返回失败？')
                    return render_template('notice.html', info=info)
                except Exception as error:
                    print(request.path, error)
                    info['type'] = 'warning'
                    info['title'] = '错误'
                    info['notice'] = '出现错误，请联系管理员！'
                    return render_template('notice.html', info=info)
        else:
            errors = adduserform.get_errors()
            print(errors)
            return jsonify({'status':400, 'errors': errors})
    else:
        pass

为了能在当前页面显示验证的错误信息，在usermanage_ajax.html页面，我使用了ajax，采用post方式提交到adduser视图处理，那么问题来了，本来程序执行到这个地方：

try:
                    general.SQL(sql)
                    info['type'] = 'success'
                    info['title'] = '添加用户成功'
                    info['notice'] = '用户' + username + ' 已添加！'
                    print('返回失败？')
                    return render_template('notice.html', info=info) #执行到这个地方返回了视图
                except Exception as error:
                    print(request.path, error)
                    info['type'] = 'warning'
                    info['title'] = '错误'
                    info['notice'] = '出现错误，请联系管理员！'
                    return render_template('notice.html', info=info)

应该返回结果的，类似下图的效果

但是，实际上却出现如下的错误：

我大概了解是因为从system/usermanage发起的请求，referer指向的是system/usermanage，所以返回到此，但是因为system/usermanage的视图函数我并没有设置POST方法，所以报了这个错误，我想问的是该怎么处理这个？以使他能达到我需要的效果（显示notice.html视图，也就是哪个类似的效果）

3、我试过的方法
如果在usermanage_ajax.html中不采用ajax方式post，而是将url写到form的action里，程序执行到这个地方是不会报错的，但是不采用ajax貌似不能在当前页显示验证的错误消息啊

try:
                    general.SQL(sql)
                    info['type'] = 'success'
                    info['title'] = '添加用户成功'
                    info['notice'] = '用户' + username + ' 已添加！'
                    print('返回失败？')
                    return render_template('notice.html', info=info) #执行到这个地方返回了视图
                except Exception as error:
                    print(request.path, error)
                    info['type'] = 'warning'
                    info['title'] = '错误'
                    info['notice'] = '出现错误，请联系管理员！'
                    return render_template('notice.html', info=info)

4、拜托各位大神帮帮忙，这个问题卡了我3天了，非常感谢。半路出家的程序猿，水平比较渣
总结一下，不要让他出现405错误，能正常返回我的notice视图
5、P.S. 还有一个问题，就是wtforms的验证即使出现了错误，为什么还是能通过提交，难道不是应该停下来等待修正输入吗？
如果是空的，页面不会提交，但是比如邮箱，虽然填了，但是格式不正确，或者手机，位数不正确（我后台已经抓取到了错误），但是页面为什么还是会提交呢？（然后就会显示那个405错误）

ajax提交wtform出现405错误

有一种算法存在返回真，不存在返回假的高性能算法，我忘记是什么了?

duckdb 的 python sdk 读取 csv 的时候，如何指定列的字段类型？

为什么 pypi 的页面上的新版本在通过 pip 获取不到？

请问在一个项目中一般是创建多个ioc容器，还是一个ioc容器？

python这句代码是什么意思？

我写的python单例 init会调用多次如何解决?

使用anaconda.navigator的时候，新建一个python的环境：那么会有推荐的python包。这些包我们默认应该安装还是不必管呢？
