        if form.is_valid():
            # 处理表单数据

            # 连接数据库
            conn = pymysql.connect(host='192.168.2.101', port=3306, user='mgs', password='abc123!Test',
                                   db='mgsdb', charset='utf8mb4')
            # 创建游标对象
            cursor = conn.cursor()
            # 执行SQL查询和更新操作
            account_id = form.cleaned_data['account_id']
            branch_name = form.cleaned_data['branch_name']
            account_balance = form.cleaned_data['account_balance']
            cursor.execute("INSERT INTO mgs_account (account_id, branch_name, account_balance ) VALUES (%s, %s, %s)", (account_id, branch_name, account_balance ))
            # 提交更改
            conn.commit()
            # 关闭游标和连接
            cursor.close()
            # 返回响应
            return render(request, 'success.html', {'name': account_id})
    else:
        form = MyForm()
    return render(request, 'my_form.html', {'form': form})

 form = MyForm(request.POST) # Convert the form sent from the web page to the set format
