一、windows下迁移access到mysql

            Windows下 Access 数据 迁移到 Mysql(5.5)数据库

1. 具体做法
    1. 在access的表中选择,文件->导出->保存类型->excel->填写文件名

       - Navicat for mysql的表中,导入向导->excel类型-》选中刚才的文件->下一步->。。。->对应目标栏位和源栏位->开始即可

       前提是:两个表的字段数据类型一致。主键会比较麻烦,可以先转化后改动主键
    2. ODBC方式连接mysql数据库 ,ODBC 做到access与mysql实时同步更新
    
    比较1和2,1是手动导入的方式,自主性强,但是相互之间不会实时更新,2更优!但是需要注意外键的关系
    
    
    
2. Access若存在外键关系
    1. 在access中制作表格时如何设置外键 
        手动建立两表一对多参照完整性(关系可以设定参照完整性,这样你在其中一个表中更改或删除记录时,将同步到另一个表)
            注:注意设置外键前一方表的关联字段必须是主键或建有唯一索引
    2. 
        
    
3. 直接mysql上存access导入过来的表,django能执行吗?   pymysql    orm   反向生成表
    
    - 将accss的表不用刻意去命名
    - python manage.py inspectdb > models.py 反向生成models.py
    - 替换models.py文件
    - python manage.py migrate
    - 正常ORM调用
    
    迁移过程问题分析:
        - 建表乱码问题
            去除带中文字段、手动添加外键等关系
        - 先正向生成models文件
        - 在将之前已经建立好关系的表直接粘贴到本数据库中
        - Python manage.py inspectdb > models.py
        - 再正向生成migrate时会报重复的错(already exists)
        - 直接 python manage.py migrate myapp --fake
        - 在已有的表上再加入外键
            - Dbtestcase
            - App01ProjFunc
        
    
4. 外键关系手动添加。。。。。  能使用吗

二、 index页面

    index.html设计
1. https://icons8.com/icons/set/find   icon图标
2.  71.0.3578.98
3. jquery.flexisel.js 是一款响应式旋转木马插件,
它可以拥有幻灯片播放,图片展示,文章展示等等,
我们今天手动把这个插件集成到wordpress中。本站
提供了DEMO下载。

4. jqgrid
5. 台架预约项目需要手动创建数据表 server_calenda 才能启用
6. gritter 
    边框提示插件
6. Ubuntu_16_04
    - D:\Documents\Virtual Machines\Ubuntu_16_04
7. 云服务器的使用
    https://mp.weixin.qq.com/s/-9pqpz5FKTgPUi_1iRYnMQ
    
table 数据表格文档 - layui.table

redis 
    - 若用户多,session服务器     
    - 对于经常访问的如首页,则用缓存服务器

to-do:
    1.设计后台管理页面
    2.做好incredidb反向生成的表,并建立外键关系正常查询
        - 考虑建表的优化
    3.虚拟机安装redis、mysql,正常使用
    4.在线浏览asp页面轮播PPT显示

    5.HTML里面Textarea换行总结
             <script>
                     //换行转回车
                     var haha=document.getElementById("SendTextArea").value;
                     haha=haha.replace('<br />','/n');
                     document.getElementById("SendTextArea").value=haha;
             </script>

三、自动化selenium爬

from selenium import webdriver

options = webdriver.ChromeOptions()

prefs = {'profile.default_content_settings.popups': 0,  # 设置为 0 禁止弹出窗口
         'download.default_directory': 'D:\\chrome_downdir'}  # 设置下载路径
options.add_experimental_option('prefs', prefs)

driver = webdriver.Chrome(chrome_options=options)
baidu = driver.get('http://www.baidu.com/')
length = len(driver.find_elements_by_tag_name("a"))
print(length)
import time

f = open('news.log', mode='a+')
links = driver.find_elements_by_tag_name("a")
for i in range(0,length):
    link = links[i]
    if not (len(link.get_attribute("href"))<33):
        f.write(str(i) +':'+link.get_attribute("href")+"\n")
        print('1111111111111')
        link.click()
        time.sleep(3)
        print('222222222222')
driver.back()

四、页面中加入查阅PPT的功能

 <div class="pdf">
    <iframe id="pdf_page" name="pdf_page" style="width:1400px;height:800px">
    </iframe>
 </div>
  <script>
    <%if Request.QueryString("id")= "17113005" then%>  
        $(document).ready(function () {
            var url = "images/media/11111.pdf";//这里就可以做url动态切换--主要是使用iframe
            $("#pdf_page").attr("src", url);
            $(".pdf").media();
        });
   
    <%elseif Request.QueryString("id")= "17113004" then%>  
        $(document).ready(function () {
            var url = "images/media/2222.pdf";//这里就可以做url动态切换--主要是使用iframe
            $("#pdf_page").attr("src", url);
            $(".pdf").media();
        });
    <%end if%>
  </script>
