I am implementing swagger using drf-yasg for django rest framework APIs in my project.
I follow the quick start section of drf-yasg. When I hit /swagger gets AssertionError: duplicate Parameters found. Below is my code and traceback.
urls.py
from drf_yasg.views import get_schema_view
from drf_yasg import openapi
schema_view = get_schema_view(
openapi.Info(
title="Snippets API",
default_version='v1',
description="Test description",
terms_of_service="https://www.google.com/policies/terms/",
contact=openapi.Contact(email="[email protected]"),
license=openapi.License(name="BSD License"),
),
public=True,
permission_classes=(permissions.AllowAny,),
)
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'),
url(r'^redoc/$', schema_view.with_ui('redoc', cache_timeout=0), name='schema-redoc'),
# path('graphql', csrf_exempt(GraphQLObservableUnboxingView.as_view(graphiql=True, schema=schema))),
]
Traceback
