天天生鲜项目学习视频
另外如果需要其他资源，比如视频中的工程文档，欢迎公众号留言
本内容持续更新直至天天生鲜项目完成！
本文主要内容：实现注册基本逻辑
本设计不涉及中间过程，直接上手最后的功能，所以自己对着视频分模块学习，把这个整个模块学习完再导入下面的代码
本文中用到的Django的一些说明书
类试图使用手册

第一章、天天生鲜项目框架搭建
第二章、天天生鲜注册功能实现
第一步
首先将static文件夹下面的register.html复制到templates中，由于CSS文件以及js文件与其不在同一路径，我们需要将头文件做如下改变
# 将头部文件做如下改变 PS:这个注释最好不要复制进去

<<span class="token operator">/</span>head>
</code></pre>
<p>另外，如果前端代码中，存在图片连接，由于图片存放在static中，因此图片也需要做如下改变，只要是图片连接都要做这种改变</p>
<pre><code class="prism language-powershell"><a <span class="token keyword">class</span>=<span class="token string">"reg_logo"</span>><img src=<span class="token string">"{% static 'images/logo02.png' %}"</span>><<span class="token operator">/</span>a>
</code></pre>
<p>最后我们的前端页面register.html中的是这样的，当然中间还存在很多改变，自己看视频，防止敲错，直接复制即可</p>

<p>mysql数据库应用小技巧</p>
<pre><code class="prism language-mysql"># 1、如何删除数据库中某个表中的数据，比如从df_user表中删除id=1的用户
delete from df_user where id=1
# 2、查看df_user表中的全部数据

本节所介绍的查询优化的技巧都是和特定版本相关的，所以对于未来mysql的版本未必适用。
1 优化count查询
对于count这个函数的网上的大部分资料都是错误的或者是理解的都是一知半解的。在做优化之前我们先来看看
真正的count()函数的作用到底是什么。
count()是一个特殊的函数，有两种非常不同的作用，他可以统计某个列值的数量，也可以统计行数。
