A connection to a list of items.

Attributes: page_info: Pagination data for this connection edges: Contains the nodes in this connection

Methods:

• resolve_node

  The identity function for the node.

  This method is used to resolve a node of a different type to the connection’s NodeType .

  By default it returns the node itself, but subclasses can override this to provide a custom implementation.

  Signature:

  def resolve_node(cls, node: Any, info: Info, kwargs: Any = {}) -> NodeType:
    ...

  Parameters:

  1. node:

     The resolved node which should return an instance of this connection’s NodeType .

     Type

     Any

  2. info:

     The strawberry execution info resolve the type name from.

• resolve_connection

  Resolve a connection from nodes.

  Subclasses must define this method to paginate nodes based on first /last /before /after arguments.

  Returns:

  The resolved Connection

  Signature:

  def resolve_connection(
      cls,
      nodes: NodeIterableType[NodeType],
      info: Info,
      before: str | None = None,
      after: str | None = None,
      first: int | None = None,
      last: int | None = None,
      kwargs: Any = {},
  ) -> AwaitableOrValue[Self]:
    ...
