Routing

plateforme.core.api.routing

This module provides routing mechanisms for the Plateforme API, extending FastAPI and Starlette features. It includes the standard route decorators for the API route configurations, and a router to organize and manage API endpoints.

APIMethod module-attribute

APIMethod = Literal[
    "DELETE",
    "GET",
    "HEAD",
    "OPTIONS",
    "PATCH",
    "POST",
    "PUT",
    "TRACE",
]

A literal type for the API HTTP methods.

APIMode module-attribute

APIMode = Literal['request', 'websocket']

A literal type for the API modes.

route module-attribute

The standard decorator for routing operations.

APIBaseRoute

Bases: Protocol

An API base route protocol.

path instance-attribute

path: str

The path for the operation. If not provided, it is automatically generated from the endpoint name.

path_regex instance-attribute

path_regex: Pattern[str]

The path regex for the operation with format /(?P<username>[^/]+)

path_format instance-attribute

path_format: str

The path format for the operation with format /{username}

param_convertors instance-attribute

param_convertors: dict[str, Convertor[Any]]

The path parameter convertors for the operation with format {"username": StringConvertor()}

endpoint instance-attribute

endpoint: Callable[..., Any]

The method endpoint for the path operation.

dependencies instance-attribute

dependencies: list[DependsInfo]

A list of dependencies to be applied to the path operation (using Depends function). Defaults to None.

name instance-attribute

name: str

The name of the path operation. It is used internally to identify the path operation.

operation_id instance-attribute

operation_id: str | None

The operation ID to be used for the path operation. By default, it is generated automatically. If you provide a custom operation ID, you need to make sure it is unique for the whole API. You can customize the operation ID generation with the parameter generate_unique_id_function. Defaults to None.

generate_unique_id_function instance-attribute

generate_unique_id_function: Union[
    APIBaseRouteIdentifier,
    DefaultPlaceholder[APIBaseRouteIdentifier],
]

A function that generates a unique ID for a given route. Defaults to generate_unique_id.

unique_id instance-attribute

unique_id: str

The unique ID for the path operation inferred from the operation ID or the given generate_unique_id_function function.

APIEndpoint

Bases: Protocol, Generic[_P, _R]

An API endpoint protocol.

APIRouter

APIRouter(**kwargs: Unpack[APIRouterConfigDict])

Bases: APIRouter

An API router to group path operations.

It is used to group path operations, for example to structure an app in multiple files. It would then be included in an APIManager class (i.e. a subclass of the FastAPI application), or in another APIRouter class (ultimately included in a manager).

Examples:

>>> from plateforme.api import APIManager, APIRouter
... manager = APIManager()
... router = APIRouter()
>>> @router.get("/users/", tags=["users"])
... async def read_users():
...     return [{"username": "Rick"}, {"username": "Morty"}]
>>> manager.include_router(router)
Note

This class is used internally within the framework and should not be used directly except for advanced use cases.

Initialize an API router.

Parameters:

Name Type Description Default

            The type to use for the response.

            It could be any valid Pydantic *field* type. So, it doesn't have to
            be a Pydantic model, it could be other things, like a `list`, `dict`,
            etc.

            It will be used for:

            * Documentation: the generated OpenAPI (and the UI at `/docs`) will
                show it as the response (JSON Schema).

                corresponding JSON.
            * Filtering: the JSON sent to the client will only contain the data
                (fields) defined in the `response_model`. If you returned an object
                that contains an attribute `password` but the `response_model` does
                not include that field, the JSON sent to the client would not have

            It could be any valid Pydantic *field* type. So, it doesn't have to
            be a Pydantic model, it could be other things, like a `list`, `dict`,
            etc.

            It will be used for:

            * Documentation: the generated OpenAPI (and the UI at `/docs`) will
                show it as the response (JSON Schema).
            * Serialization: you could return an arbitrary object and the
                `response_model` would be used to serialize that object into the
                corresponding JSON.
            * Filtering: the JSON sent to the client will only contain the data
                (fields) defined in the `response_model`. If you returned an object
                that contains an attribute `password` but the `response_model` does
                not include that field, the JSON sent to the client would not have
                that `password`.
            * Validation: whatever you return will be serialized with the
                `response_model`, converting any data as necessary to generate the
                corresponding JSON. But if the data in the object returned is not
                valid, that would mean a violation of the contract with the client,
                so it's an error from the API developer. So, FastAPI will raise an
                error and return a 500 error code (Internal Server Error).

            It could be any valid Pydantic *field* type. So, it doesn't have to
            be a Pydantic model, it could be other things, like a `list`, `dict`,
            etc.

            It will be used for:

            * Documentation: the generated OpenAPI (and the UI at `/docs`) will
                show it as the response (JSON Schema).
            * Serialization: you could return an arbitrary object and the
                `response_model` would be used to serialize that object into the
                corresponding JSON.
            * Filtering: the JSON sent to the client will only contain the data
                (fields) defined in the `response_model`. If you returned an object
                that contains an attribute `password` but the `response_model` does
                not include that field, the JSON sent to the client would not have
                that `password`.
            * Validation: whatever you return will be serialized with the
                `response_model`, converting any data as necessary to generate the
                corresponding JSON. But if the data in the object returned is not
                valid, that would mean a violation of the contract with the client,
                so it's an error from the API developer. So, FastAPI will raise an
                error and return a 500 error code (Internal Server Error).

            It could be any valid Pydantic *field* type. So, it doesn't have to
            be a Pydantic model, it could be other things, like a `list`, `dict`,
            etc.

            It will be used for:

            * Documentation: the generated OpenAPI (and the UI at `/docs`) will
                show it as the response (JSON Schema).
            * Serialization: you could return an arbitrary object and the
                `response_model` would be used to serialize that object into the
                corresponding JSON.
            * Filtering: the JSON sent to the client will only contain the data
                (fields) defined in the `response_model`. If you returned an object
                that contains an attribute `password` but the `response_model` does
                not include that field, the JSON sent to the client would not have
                that `password`.
            * Validation: whatever you return will be serialized with the
                `response_model`, converting any data as necessary to generate the
                corresponding JSON. But if the data in the object returned is not
                valid, that would mean a violation of the contract with the client,
                so it's an error from the API developer. So, FastAPI will raise an
                error and return a 500 error code (Internal Server Error).

            It could be any valid Pydantic *field* type. So, it doesn't have to
            be a Pydantic model, it could be other things, like a `list`, `dict`,
            etc.

            It will be used for:

            * Documentation: the generated OpenAPI (and the UI at `/docs`) will
                show it as the response (JSON Schema).
            * Serialization: you could return an arbitrary object and the
                `response_model` would be used to serialize that object into the
                corresponding JSON.
            * Filtering: the JSON sent to the client will only contain the data
                (fields) defined in the `response_model`. If you returned an object
                that contains an attribute `password` but the `response_model` does
                not include that field, the JSON sent to the client would not have
                that `password`.
            * Validation: whatever you return will be serialized with the
                `response_model`, converting any data as necessary to generate the
                corresponding JSON. But if the data in the object returned is not
                valid, that would mean a violation of the contract with the client,
                so it's an error from the API developer. So, FastAPI will raise an
                error and return a 500 error code (Internal Server Error).

If you returned an object\n                    that contains an attribute `password` but the `response_model` does\n                    not include that field, the JSON sent to the client would not have\n                    that `password`.\n                * Validation: whatever you return will be serialized with the\n                    `response_model`, converting any data as necessary to generate the\n                    corresponding JSON. But if the data in the object returned is not\n                    valid, that would mean a violation of the contract with the client,\n                    so it's an error from the API developer.

            It could be any valid Pydantic *field* type. So, it doesn't have to
            be a Pydantic model, it could be other things, like a `list`, `dict`,
            etc.

            It will be used for:

            * Documentation: the generated OpenAPI (and the UI at `/docs`) will
                show it as the response (JSON Schema).
            * Serialization: you could return an arbitrary object and the
                `response_model` would be used to serialize that object into the
                corresponding JSON.
            * Filtering: the JSON sent to the client will only contain the data
                (fields) defined in the `response_model`. If you returned an object
                that contains an attribute `password` but the `response_model` does
                not include that field, the JSON sent to the client would not have
                that `password`.
            * Validation: whatever you return will be serialized with the
                `response_model`, converting any data as necessary to generate the
                corresponding JSON. But if the data in the object returned is not
                valid, that would mean a violation of the contract with the client,
                so it's an error from the API developer. So, FastAPI will raise an
                error and return a 500 error code (Internal Server Error).

            be a Pydantic model, it could be other things, like a `list`, `dict`,
            etc.

            It will be used for:

            * Documentation: the generated OpenAPI (and the UI at `/docs`) will
                show it as the response (JSON Schema).
            * Serialization: you could return an arbitrary object and the
                `response_model` would be used to serialize that object into the
                corresponding JSON.
            * Filtering: the JSON sent to the client will only contain the data
                (fields) defined in the `response_model`. If you returned an object
                that contains an attribute `password` but the `response_model` does
                not include that field, the JSON sent to the client would not have
                that `password`.
            * Validation: whatever you return will be serialized with the
                `response_model`, converting any data as necessary to generate the
                corresponding JSON. But if the data in the object returned is not
                valid, that would mean a violation of the contract with the client,
                so it's an error from the API developer. So, FastAPI will raise an
                error and return a 500 error code (Internal Server Error).

            be a Pydantic model, it could be other things, like a `list`, `dict`,
            etc.

            It will be used for:

            * Documentation: the generated OpenAPI (and the UI at `/docs`) will
                show it as the response (JSON Schema).
            * Serialization: you could return an arbitrary object and the
                `response_model` would be used to serialize that object into the
                corresponding JSON.
            * Filtering: the JSON sent to the client will only contain the data
                (fields) defined in the `response_model`. If you returned an object
                that contains an attribute `password` but the `response_model` does
                not include that field, the JSON sent to the client would not have
                that `password`.
            * Validation: whatever you return will be serialized with the
                `response_model`, converting any data as necessary to generate the
                corresponding JSON. But if the data in the object returned is not
                valid, that would mean a violation of the contract with the client,
                so it's an error from the API developer. So, FastAPI will raise an
                error and return a 500 error code (Internal Server Error).
