Common methods provided by ActivityPub actors (community and person). Not all methods are implemented by all actors.

Common functions for ActivityPub objects, which are implemented by most (but not all) objects and actors in Lemmy.

Functions

Takes in a shortname of the type dessalines@xyz.tld or dessalines (assumed to be local), and outputs the actor id. Used in the API for communities and users.

check_community_or_site_ban

check_is_apub_id_valid

Checks if the ID is allowed for sending or receiving.

find_object_by_id

find_post_or_comment_by_id

Tries to find a post or comment in the local database, without any network requests. This is used to handle deletions and removals, because in case we dont have the object, we can simply ignore the activity.

generate_apub_endpoint

Generates the ActivityPub ID for a given object type and ID.

generate_apub_endpoint_for_domain

Generates an apub endpoint for a given domain, IE xyz.tld

generate_followers_url

generate_inbox_url

generate_moderators_url

generate_shared_inbox_url

get_activity_to_and_cc

get_community_from_to_or_cc

insert_activity

Store a sent or received activity in the database, for logging purposes. These records are not persistent.
