一个 django 项目，下面有两个 app，这两个 app 会分别调用两个 html，但这个两个 html 名字相同。应该如何配置？

例如：

文件结构是这样的：
(django_18)chale@chale-pc:~/learning/mayday/mayday$ tree
.
(django_18)chale@chale-pc:~/learning/mayday/mayday$ tree
.
├── apptest
│   ├── admin.py
│   ├── __init__.py
│   ├── models.py
│   ├── templates
│   ├── tests.py
│   └── views.py
├── db.sqlite3
├── main
│   ├── admin.py
│   ├── __init__.py
│   ├── migrations
│   │   ├── 0001_initial.py
│   │   └── __init__.py
│   ├── models.py
│   ├── templates
│   ├── tests.py
│   └── views.py
├── manage.py
└── mayday
├── __init__.py
├── settings.py
├── urls.py
└── wsgi.py



log 是这样的：
Django tried loading these templates, in this order:
Using loader django.template.loaders.filesystem.Loader:
Using loader django.template.loaders.app_directories.Loader:
/home/chale/.virtualenvs/django_18/local/lib/python2.7/site-packages/django/contrib/admin/templates/index.html (File does not exist)
/home/chale/.virtualenvs/django_18/local/lib/python2.7/site-packages/django/contrib/auth/templates/index.html (File does not exist)
/home/chale/learning/mayday/mayday/main/templates/index.html (File does not exist)
/home/chale/learning/mayday/mayday/apptest/templates/index.html (File does not exist)


本人菜鸟，大神轻喷。
