使用Django Rest Framework的Heroku中的TemplateDoesNotExist

Question

我安装了用于在Heroku中打开休息服务的djangorestframework。

当我在本地环境中，我有以下消息打开网站：

TemplateDoesNotExist at/

rest_framework/api.html 

Request Method:  GET 
Request URL: http://192.168.56.102:8000/ 
Django Version:  1.9.2 
Exception Type:  TemplateDoesNotExist 
Exception Value:  

rest_framework/api.html 

Exception Location:  /home/_ws_/rest/gps2/venv/lib/python2.7/site-packages/django/template/loader.py in get_template, line 43

我该怎么办？这可能与settings.py文件有关。

矿山是官方矿山，为数据库提供改造（在本例中为空）并添加轨道项目。

我也有消息：

Template-loader postmortem 

Django tried loading these templates, in this order: 

Using engine django: 

    django.template.loaders.filesystem.Loader: /home/_ws_/rest/gps2/templates/rest_framework/api.html (Source does not exist) 
    django.template.loaders.app_directories.Loader: /home/_ws_/rest/gps2/venv/lib/python2.7/site-packages/django/contrib/admin/templates/rest_framework/api.html (Source does not exist) 
    django.template.loaders.app_directories.Loader: /home/_ws_/rest/gps2/venv/lib/python2.7/site-packages/django/contrib/auth/templates/rest_framework/api.html (Source does not exist) 

---

该文件实际上位于：

/home/_ws_/rest/gps2/venv/lib/python2.7/site-packages/rest_framework/templates/rest_framework/api.html 

我怎样才能得到这个目录？

Answer 1

您还没有将"rest_framework"添加到您的INSTALLED_APPS设置中，如the installation docs中所述。

如果没有这些，Django将不会在DRF目录中查找相关模板。
