第三百七十七节，Django+Xadmin打造上线标准的在线教育平台—apps目录建立，以及数据表生成
apps目录建立
我们创建一个apps目录，将所有的app放到apps目录里去，这样方便管理，也使目录更清楚，不管有多少app都统一到apps目录里去
设置python可以识别apps目录路径
注意：我们在创建app后，python会自动到paa文件夹中找到相应的文件运行，当我们移动app到apps文件夹后，python程序将无法找到相应的文件了，
当我们移动app到apps文件夹后，此时我们需要两步解决
第一步，解决PyCharm无法识别paa文件的方法，在PyCharm将apps设置成python可识别路径，在apps文件夹鼠标右键-标记目录为-Sources Root
第二步，在settings.py设置文件，将apps目录设置成python可识别目录，

数据表生成
生成表需要在PyCharm的终端输入命令，先输入 makemigrations 然后在输入 migrate 来生成表
