Schemas generated by generators.py exclude urlpatterns with same root node and action

• [] I have included a failing test as a pull request. (If you are unable to do so we can still accept the issue.)

Steps to reproduce

• Use DRF with coreAPI and pyyaml support
• Include multiple list-action type URLpatterns in urls.py, e.g.

urlpatterns = [
    url(r"^api/status/", views.status, name="aggregated_status"),  # aggregated status of page and system
    url(r"^api/status/page/", views.status_page, name="status_page"),  # page status only
]

• Generate a schema ./manage.py generateschema --format=openapi
• NOTE: problem only occurs with formats openapi and openapi-json. With corejson there is no issue.

Expected behavior

• Schema including all paths

info:
  description: Get statuses yay
  title: Status API
  version: ''
openapi: 3.0.0
paths:
  /api/status/:
    get:
      description: Aggregated system and page status
      operationId: status_list
      tags:
      - status
  /api/status/page/:
    get:
      description: Page status
      operationId: status_page_list
      tags:
      - status
servers:
- url: ''

Actual behavior

• Only top-level pattern is included (i.e. /api/status/)

info:
  description: Get statuses yay
  title: Status API
  version: ''
openapi: 3.0.0
paths:
  /api/status/:
    get:
      description: Aggregated system and page status
      operationId: status_list
      tags:
      - status
servers:
- url: ''

Code

I believe the culprit to be here:

renderers.py::_BaseOpenAPIRenderer

    def get_paths(self, document):
        paths = {}

        tag = None
        for name, link in document.links.items():
            path = urlparse.urlparse(link.url).path
            method = link.action.lower()
            paths.setdefault(path, {})
            paths[path][method] = self.get_operation(link, name, tag=tag)

        for tag, section in document.data.items():
            for name, link in section.links.items():
                path = urlparse.urlparse(link.url).path
                method = link.action.lower()
                paths.setdefault(path, {})
                paths[path][method] = self.get_operation(link, name, tag=tag)

        return paths
