Django REST Framework Swagger 2.0

Question

Having a hard time configuring Swagger UI Here are the very explanatory docs: https://django-rest-swagger.readthedocs.io/en/latest/

YAML docstrings are deprecated. Does somebody know how to configure Swagger UI from within the python code? or what file should I change to group api endpoints, to add comments to each endpoint, to add query parameter fields in Swagger UI?

Answer 1

This is how I managed to do it:

base urls.py

urlpatterns = [
...
url(r'^api/', include('api.urls', namespace='api')),
url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework')),
...
]

api.urls.py

urlpatterns = [
url(r'^$', schema_view, name='swagger'),
url(r'^article/(?P<pk>[0-9]+)/$', 
    ArticleDetailApiView.as_view(actions={'get': 'get_article_by_id'}), 
    name='article_detail_id'),
url(r'^article/(?P<name>.+)/(?P<pk>[0-9]+)/$', 
    ArticleDetailApiView.as_view(actions={'get': 'get_article'}), 
    name='article_detail'),
]

api.views.py. In MyOpenAPIRenderer I update the data dict to add description, query fields and to update type or required features.

class MyOpenAPIRenderer(OpenAPIRenderer):
    def add_customizations(self, data):
        super(MyOpenAPIRenderer, self).add_customizations(data)
        data['paths']['/article/{name}/{pk}/']['get'].update(
            {'description': 'Some **description**',
             'parameters': [{'description': 'Add some description',
                             'in': 'path',
                             'name': 'pk',
                             'required': True,
                             'type': 'integer'},
                            {'description': 'Add some description',
                             'in': 'path',
                             'name': 'name',
                             'required': True,
                             'type': 'string'},
                            {'description': 'Add some description',
                             'in': 'query',
                             'name': 'a_query_param',
                             'required': True,
                             'type': 'boolean'},
                            ]
             })
        # data['paths']['/article/{pk}/']['get'].update({...})
        data['basePath'] = '/api'  

@api_view()
@renderer_classes([MyOpenAPIRenderer, SwaggerUIRenderer])
def schema_view(request):
    generator = SchemaGenerator(title='A title', urlconf='api.urls')
    schema = generator.get_schema(request=request)
    return Response(schema)


class ArticleDetailApiView(ViewSet):

    @detail_route(renderer_classes=(StaticHTMLRenderer,))
    def get_article_by_id(self, request, pk):
        pass

    @detail_route(renderer_classes=(StaticHTMLRenderer,))
    def get_article(self, request, name, pk):
        pass

update for django-rest-swagger (2.0.7): replace only add_customizations with get_customizations.

views.py

class MyOpenAPIRenderer(OpenAPIRenderer):
    def get_customizations(self):
        data = super(MyOpenAPIRenderer, self).get_customizations()
        data['paths'] = custom_data['paths']
        data['info'] = custom_data['info']
        data['basePath'] = custom_data['basePath']
        return data

You can read the swagger specification to create custom data.
