TemplateDoesNotExist in Heroku using Django Rest Framework

Question

我安装了 djangorestframework 来在 Heroku 中打开一个休息服务。

当我在本地环境中打开网站时，我收到以下消息：

TemplateDoesNotExist at /
rest_framework/api.html
Request Method:     GET
Request URL:    http://192.168.56.102:8000/
Django Version:     1.9.2

我该怎么办？这可能与 settings.py 文件有关。

我的是官方的，对数据库进行了移动（在本例中为空）并添加了一个轨道项目。

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

如何获取此目录？

Answer 1

您尚未将"rest_framework"添加到INSTALLED_APPS设置中，如安装文档中所述。

没有它，Django 将不会在 DRF 目录中查找相关模板。
