pyramid_apispec

pyramid_apispec allows you to create an OpenAPI specification file using apispec and an online OpenAPI explorer using the Swagger UI project for your Pyramid application and its marshmallow schemas.

Installation

pip install pyramid_apispec

Basic usage

Check out the demo folder and minimal application example by running:

pip install -e .[demo]
python demo/app.py

You can then visit your API explorer page at http://0.0.0.0:6543/api-explorer.

Examples

Hinting a route and its view:

@view_config(route_name='foo_route', renderer='json')
def foo_view():
    """A greeting endpoint.

    ---
    x-extension: value
    get:
        description: some description
        responses:
            200:
                description: response for 200 code
                schema:
                    $ref: #/definitions/BarBodySchema
    """
    return 'hi'

Rendering the spec as JSON response:

from pyramid_apispec.helpers import add_pyramid_paths

@view_config(route_name='openapi_spec', renderer='json')
def api_spec(request):
    spec = APISpec(
        title='Some API',
        version='1.0.0',
        plugins=[
            'apispec.ext.marshmallow'
        ],
    )
    # using marshmallow plugin here
    spec.definition('SomeFooBody', schema=MarshmallowSomeFooBodySchema)

    # inspect the `foo_route` and generate operations from docstring
    add_pyramid_paths(spec, 'foo_route', request=request)

    # inspection supports filtering via pyramid add_view predicate arguments
    add_pyramid_paths(
        spec, 'bar_route', request=request, request_method='post')
    return spec.to_dict()

Adding the API explorer view

To complement the specification file generation, this package can also provide an API explorer for your application's API via the Swagger UI project:

config.include('pyramid_apispec.views')
config.pyramid_apispec_add_explorer(
    spec_route_name='openapi_spec')

By default you need to pass the route name of the view that serves the OpenAPI specification in your application. If needed you can specify a Pyramid permission or custom callable (script_generator argument) to override the default JavaScript configuration of Swagger UI.

The default URL for the explorer is /api-explorer. This setting is controlled via the explorer_route_path argument.
