Flask-SQLalchemy

1.配置：https://flask-sqlalchemy.palletsprojects.com/en/2.x/config/

2.使用命令自動生成model

<input autocomplete="off" type="search" class="ant-select-selection-search-input" role="combobox" aria-haspopup="listbox" aria-owns="rc_select_9_list" aria-autocomplete="list" aria-controls="rc_select_9_list" aria-activedescendant="rc_select_9_list_0" value="" id="rc_select_9">Shell

收 起

<textarea autocorrect="off" autocapitalize="off" spellcheck="false" tabindex="0" style="position: absolute; bottom: -1em; padding: 0px; width: 1000px; height: 1em; min-height: 1em; outline: none;"></textarea>

<pre class="CodeMirror-line-like">xxxxxxxxxx</pre>

1

<pre class=" CodeMirror-line " role="presentation">pip install flask-sqlacodegen</pre>

2

<pre class=" CodeMirror-line " role="presentation">flask-sqlacodegen "mysql+pymysql://用戶名:密碼@host:port/數(shù)據(jù)庫" --tables 表 --outfile "導出地址" --flask</pre>

注意：

Blueprint 并不是一個完整的應用，它不能獨立于應用運行，而必須要注冊到某一個應用中。

注冊的順序是先將藍圖綁定到 api 中，這時 api 既有自身的功能，還有藍圖的功能，這是創(chuàng)建 api，藍圖還需要注冊到 app 中，最后使用 api 進行路由注冊

注冊藍圖和路由的順序不能反，因為藍圖綁定到 api 中了

常用鉤子函數(shù)
