class cowbird.api.generic.RemoveSlashNotFoundViewFactory(notfound_view: Callable[[pyramid.request.Request], cowbird.typedefs.AnyResponseType] | None = None)

Bases: object

Utility that will try to resolve a path without appended slash if one was provided.

__call__(request: pyramid.request.Request) → cowbird.typedefs.AnyResponseType

cowbird.api.generic.internal_server_error(request: pyramid.request.Request) → pyramid.httpexceptions.HTTPException

Overrides default HTTP.

cowbird.api.generic.not_found_or_method_not_allowed(request: pyramid.request.Request) → pyramid.httpexceptions.HTTPException

Overrides the default HTTPNotFound [404] by appropriate HTTPMethodNotAllowed [405] when applicable.

Not found response can correspond to underlying process operation not finding a required item, or a completely unknown route (path did not match any existing API definition). Method not allowed is more specific to the case where the path matches an existing API route, but the specific request method (GET, POST, etc.) is not allowed on this path.

Without this fix, both situations return [404] regardless.

cowbird.api.generic.guess_target_format(request: pyramid.request.Request) → Tuple[str, bool]

Guess the best applicable response Content-Type header according to request Accept header and format query, or defaulting to CONTENT_TYPE_JSON.

Returns:

tuple of matched MIME-type and where it was found (True: header, False: query)

cowbird.api.generic.validate_accept_header_tween(handler: Callable[[pyramid.request.Request], pyramid.response.Response], registry: pyramid.registry.Registry) → Callable[[pyramid.request.Request], pyramid.response.Response]

Tween that validates that the specified request Accept header or format query (if any) is supported by the application and for the given context.

Raises:

HTTPNotAcceptable – if desired Content-Type is not supported.

cowbird.api.generic.apply_response_format_tween(handler: Callable[[pyramid.request.Request], pyramid.httpexceptions.HTTPException], registry: pyramid.registry.Registry) → Callable[[pyramid.request.Request], pyramid.response.Response]

Tween that obtains the request Accept header or format query (if any) to generate the response with the desired Content-Type.

The target Content-Type is expected to have been validated by validate_accept_header_tween() beforehand to handle not-acceptable errors.

The tween also ensures that additional request metadata extracted from get_request_info() is applied to the response body if not already provided by a previous operation.

cowbird.api.generic.get_exception_info(response: pyramid.httpexceptions.HTTPException | pyramid.request.Request | pyramid.response.Response, content: cowbird.typedefs.JSON | None = None, exception_details: bool = False) → cowbird.typedefs.JSON

Obtains additional exception content details about the response according to available information.

cowbird.api.generic.get_request_info(request: pyramid.request.Request | pyramid.httpexceptions.HTTPException, default_message: str | None = None, exception_details: bool = False) → cowbird.typedefs.JSON

Obtains additional content details about the request according to available information.
