小编mer*_*iii的帖子

我在 pythonanywhere 上发布的 Flask 应用程序有问题。这是一个仪表板，如果我单击帖子的标题，它应该会显示帖子的详细信息。我想在删除之前添加确认消息。我怎样才能做到？现在我尝试使用 javascript，但它不起作用。下面是我的代码。

应用程序

import MySQLdb as mysql
con = mysql.connect("host", "username", "password", "database")
con.ping(True)

@app.route('/deleteschool/<int:School_Id>')
def deleteschool(School_Id):
try:
    if session.get('user'):
        #con = mysql.connect()
        cursor = con.cursor()
        query_string = "DELETE FROM school WHERE School_Id = '{School_Id}'".format(School_Id=School_Id)
        cursor.execute(query_string)
        #cursor.execute("DELETE from school where School_Id=%s", (School_Id))
        delete=cursor.fetchall()
        if len(delete) is 0:

            con.commit()
            return redirect('/getSchoolList')
        else:
            return redirect('/error')


    else:
        return redirect('/error')
except Exception as e:

    return redirect('/error')
