Installing

Installing the package from pypi:

pip install drf-yasg2

Given the numerous methods to manually customize the generated schema, it makes sense to validate the result to ensure it still conforms to OpenAPI 2.0. To this end, validation is provided at the generation point using Python Swagger libraries, and can be activated by passing validators=['ssv'] to get_schema_view; if the generated schema is not valid, a SwaggerValidationError is raised by the handling codec.

To provide the built-in validation mechanisms you can install the extra requirements:

pip install drf-yasg2[validation]

Usage

Checkout the live demo!

Add the package to INSTALLED_APPS:

   INSTALLED_APPS = [
      ...
      'drf_yasg2',
      ...
   ]

Add the endpoints to urlpatterns:

   from django.urls import path, re_path
   from rest_framework import permissions
   from drf_yasg2.views import get_schema_view
   from drf_yasg2 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="[e-mail]"),
         license=openapi.License(name="BSD License"),
      ),
      public=True,
      permission_classes=(permissions.AllowAny,),
   )

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

This exposes 4 endpoints:

• A JSON view of your API specification at /swagger.json
• A YAML view of your API specification at /swagger.yaml
• A swagger-ui view of your API specification at /swagger/
• A ReDoc view of your API specification at /redoc/
