用户操作相关models设计：

课程咨询/课程评论/消息数量提醒/用户和课程之间的关系

operation/models.py

UserFavorite.fav_type的对应关系

把新建的app注册到settings.py中，并执行数据库migrationsh和migrate操作。

新建apps目录，并将courses/operation/users/organization四个app加入到目录下。

修改settings.py如下：

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.insert(0, os.path.join(BASE_DIR, 'apps'))
