   'django.contrib.staticfiles',  # required for serving swagger ui's css/js files
   'drf_yasg',
   ...
]

In urls.py:

...
from rest_framework import permissions
from drf_yasg.views import get_schema_view

schema_view = get_schema_view(
   openapi.Info(

urlpatterns = [
   url(r'^swagger(?P<format>\.json|\.yaml)$', schema_view.without_ui(cache_timeout=0), name='schema-json'),
   url(r'^swagger/$', schema_view.with_ui('swagger', cache_timeout=0), name='schema-swagger-ui'),
