# flask\_script插件的使用 作用就是通過命令行來操作flask 新建一個python文件 名字manage.py來存放配置 簡單測試 ``` <pre class="calibre13">``` <span class="token2">from</span> flask_script <span class="token2">import</span> Manager #導入app <span class="token2">from</span> app <span class="token2">import</span> app manage <span class="token">=</span> <span class="token3">Manager</span><span class="token1">(</span>app<span class="token1">)</span> #寫命令 #首先設置裝飾器 @manage<span class="token1">.</span>command def <span class="token3">runserver</span><span class="token1">(</span><span class="token1">)</span><span class="token1">:</span> <span class="token3">print</span><span class="token1">(</span><span class="token4">'服務器已經啟動'</span><span class="token1">)</span> <span class="token2">if</span> __name__ <span class="token">==</span> <span class="token4">'__main__'</span><span class="token1">:</span> manage<span class="token1">.</span><span class="token3">run</span><span class="token1">(</span><span class="token1">)</span> ``` ``` 在虛擬環境命令行輸入 python [manage.py](http://manage.py) runserver 即可激活函數runserver 與數據庫相關的命令重新創建一個文件db\_script.py不是作為主文件 是讓manage.py引用 ``` <pre class="calibre13">``` <span class="token2">from</span> flask_script <span class="token2">import</span> Manager DBManager <span class="token">=</span> <span class="token3">Manager</span><span class="token1">(</span><span class="token1">)</span>#因為是為了讓manage<span class="token1">.</span>py引用不是作為主app 所以可以不用引入app #開始寫命令 @DBManager<span class="token1">.</span>command def <span class="token3">init</span><span class="token1">(</span><span class="token1">)</span><span class="token1">:</span> <span class="token3">print</span><span class="token1">(</span><span class="token4">'數據庫初始化'</span><span class="token1">)</span> @DBManager<span class="token1">.</span>command def <span class="token3">migrate</span><span class="token1">(</span><span class="token1">)</span><span class="token1">:</span> <span class="token3">print</span><span class="token1">(</span><span class="token4">'數據庫遷移'</span><span class="token1">)</span> ``` ``` 在manage.py進行加載 ``` <pre class="calibre14">``` <span class="token2">from</span> flask_script <span class="token2">import</span> Manager #導入app <span class="token2">from</span> app <span class="token2">import</span> app <span class="token2">from</span> db_script <span class="token2">import</span> DBManager manager <span class="token">=</span> <span class="token3">Manager</span><span class="token1">(</span>app<span class="token1">)</span> #寫命令 #首先設置裝飾器 @manager<span class="token1">.</span>command def <span class="token3">runserver</span><span class="token1">(</span><span class="token1">)</span><span class="token1">:</span> <span class="token3">print</span><span class="token1">(</span><span class="token4">'服務器已經啟動'</span><span class="token1">)</span> manager<span class="token1">.</span><span class="token3">add_command</span><span class="token1">(</span><span class="token4">'db'</span><span class="token1">,</span>DBManager<span class="token1">)</span> <span class="token2">if</span> __name__ <span class="token">==</span> <span class="token4">'__main__'</span><span class="token1">:</span> manager<span class="token1">.</span><span class="token3">run</span><span class="token1">(</span><span class="token1">)</span> <span><span class="token4">``</span></span>` ``` ```
