一、windows下迁移access到mysql
Windows下 Access 数据 迁移到 Mysql(5.5)数据库 . 具体做法
. 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
. 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 . Access若存在外键关系
. 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
. . 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 . 外键关系手动添加。。。。。 能使用吗
二、 index页面
index.html设计
. https://icons8.com/icons/set/find icon图标
. 71.0.3578.98
. 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。
- http://www.511yj.com/wordpress-flexisel-js.html
. jqgrid
. 台架预约项目需要手动创建数据表 server_calenda 才能启用
. gritter
边框提示插件
. Ubuntu_16_04
- D:\Documents\Virtual Machines\Ubuntu_16_04
. 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
JWT
https://www.jianshu.com/p/576dbf44b2ae
第一部分我们称它为头部（header),第二部分我们称其为载荷
（payload, 类似于飞机上承载的物品)，第三部分是签证（signature).
gritter
像logo一样的广告显示
to-do:
.设计后台管理页面
.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
.虚拟机安装redis、mysql，正常使用
.在线浏览asp页面轮播PPT显示
- jquery给未来元素添加style的属性 https://zhidao.baidu.com/question/431431850462605412.html

.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': , # 设置为 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(,length):
link = links[i]
if not (len(link.get_attribute("href"))<):
f.write(str(i) +':'+link.get_attribute("href")+"\n")
print('')
link.click()
time.sleep()
print('')
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")= "" 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")= "" 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>
