dvAdminFor function
What the backend should do with path.
authenticated is the caller's state as the application's own auth
decided it -- this does not authenticate anybody, it decides what an
already-known answer means for this route.
Implementation
DVAdminRequest dvAdminFor(
String path,
DVAdminMount mount, {
required bool authenticated,
}) {
// The mount, not the default path. A project that moved its admin
// somewhere private must not lose the check by doing so.
if (!mount.owns(path)) return DVAdminRequest.notTheAdmin;
if (!mount.enabled) return DVAdminRequest.hidden;
if (mount.requiresAuth && !authenticated) return DVAdminRequest.hidden;
return DVAdminRequest.serve;
}
