昨天在Flask 初始化數(shù)據(jù)的時(shí)候，想使用命令的Flask命令添加自己想要的命令進(jìn)行初始化數(shù)據(jù)庫(kù)操作，卻怎么都無(wú)法在flask命令添加自己的自定義命令，網(wǎng)上搜索的很多辦法，最后自己看了N多文章才找到方法，下面總結(jié)一下：

1、編寫(xiě)自己的啟動(dòng)flask app的 .py文件
2、運(yùn)行，啟動(dòng)flask app
3、把自己的flask app加入到環(huán)境變量中

export FLASK_APP=你自己?jiǎn)?dòng)flask app 的py文件的絕對(duì)路徑

4、命令行執(zhí)行

flask --help
Usage: flask [OPTIONS] COMMAND [ARGS]...

  A general utility script for Flask applications.

  Provides commands from Flask, extensions, and the application. Loads the
  application defined in the FLASK_APP environment variable, or from a
  wsgi.py file. Setting the FLASK_ENV environment variable to 'development'
  will enable debug mode.

    $ export FLASK_APP=hello.py
    $ export FLASK_ENV=development
    $ flask run

Options:
  --version  Show the flask version
  --help     Show this message and exit.

Commands:
  init    Initialize Albumy.
  initdb  Initialize the database.
  routes  Show the routes for the app.
  run     Runs a development server.
  shell   Runs a shell in the app context.

就會(huì)發(fā)現(xiàn) Commands 出現(xiàn)了自己添加的自定義命令
