Why newly created project doesn't display built-in API Django documentation?

Question

I have a problem described in this post I have no idea what is the reason of the problem so I decided to create a new project both in Docker like without it. In both cases I get the same problem. To wit to newly created project I add only to urls.py :

from rest_framework.documentation import include_docs_urls

API_TITLE = 'API title'
API_DESCRIPTION = '...'

urlpatterns = [
    url(r'^docs/', include_docs_urls(title=API_TITLE, description=API_DESCRIPTION))
]

and in Docker requirements.txt I add coreapi . In case of project without Docker I install via virtualenv pip3 install coreapi . That is all what in my opinion I should do in order to get a view like at the top of this site from documentation Obviously at http://localhost:8000/docs/ However in both cases I get

TemplateDoesNotExist at /docs/

rest_framework/docs/index.html

Django tried loading these templates, in this order:

Using engine django:

django.template.loaders.app_directories.Loader: /usr/local/lib/python3.6/site-packages/django/contrib/admin/templates/rest_framework/docs/index.html (Source does not exist)

django.template.loaders.app_directories.Loader: /usr/local/lib/python3.6/site-packages/django/contrib/auth/templates/rest_framework/docs/index.html (Source does not exist)

(in virtualenv there is only different path)

Does anyone have an idea what might be wrong? If more details will be needed I will add it immediately to this post, just let me know.

UPDATE When I add rest_framowork to INSTALLED_APPS I get:

AttributeError at /docs/

UPDATE2 I have in my app on heroku rest_framowork at the top of INSTALLED_APPS however http://myapp.herokuapp.com/docs/ returns:

SOLTUION I used djangorestframework==3.6.2 instead of djangorestframework==3.6.3 in requirements.txt. I have no idea why version 3.6.3 doesn't work.

这可能意味着您没有在settings.py文件中将rest_framework添加到INSTALLED_APPS中。
