'StaticResource' object has no attribute 'add_route'

[kamikaze]

when router has a static resource in routes... then this code fails:

https://github.com/aio-libs/aiohttp-cors/blob/master/aiohttp_cors/urldispatcher_router_adapter.py#L341

with:
AttributeError: 'StaticResource' object has no attribute 'add_route'

[kamikaze]

actually trying to get aiohttp_swagger json file being exposed with CORS headers...

def setup_routes(app):
    app.router.add_routes(routes)
    setup_swagger(app, api_base_url='/api/v2', swagger_url='/api/v2/doc')
    cors = aiohttp_cors.setup(app, defaults={
        "*": aiohttp_cors.ResourceOptions(
            allow_credentials=True,
            expose_headers="*",
            allow_headers="*",
        )
    })

    for route in list(app.router.routes()):
        cors.add(route)

in #130 author switched to cors.add(route) which is already in my example

Made this as a workaround. Isn't it a bug?

def setup_routes(app):
    app.router.add_routes(routes)
    setup_swagger(app, api_base_url='/api/v2', swagger_url='/api/v2/doc')

    cors = aiohttp_cors.setup(app, defaults={
        "*": aiohttp_cors.ResourceOptions(
            allow_credentials=True,
            expose_headers="*",
            allow_headers="*",
        )
    })

    for route in list(app.router.routes()):
        if not isinstance(route.resource, StaticResource): # <<< WORKAROUND
            cors.add(route)

Discussed on gitter already but I copy the answer for future readers:
Replace iteration over routes with resources:

    for resource in list(app.router.resources()):
            cors.add(resource)
