Extending Pagination classes

[david-welch]

I am wondering if extending the Pagination classes is supported. For instance, would it be possible to extend CursorPagination to add 'previous' cursor as well as link headers. I haven't found a way to do this that doesn't break OpenAPI schema generation. I can create a Page class from BaseModel but the schema is empty. Alternatively, I tried to adapt the current implementation of CursorPagination like:

@dataclass
class Page(Generic[T]):
    data: List[T]
    total: int
    previous_cursor: str = None
    next_cursor: str = None
    next: str = None  # noqa: A003
    previous: str = None
    headers: dict = None

But this throws an exception ImproperlyConfiguredException(f"cannot generate OpenAPI schema for generic type {field_type}").
