Question

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

当我在本地环境中打开网站时，我收到以下消息：

TemplateDoesNotExist at /

我该怎么办？这可能与settings.py文件有关。

Mine是官方版本，具有数据库的mofification（在此示例中为空）并添加了track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"添加到您的INSTALLED_APPS设置中，如the installation docs中所述。

如果没有它，Django将不会在DRF目录中查找相关模板。

使用Django Rest Framework在Heroku中使用TemplateDoesNotExist
