Use the API to get the LrFolder of an LrPhoto

[dansmith21]

This should be easy, but there doesn't seem to be an obvious way to get the LrFolder of an LrPhoto in the API. For collections, there's photo:getContainedCollections(), but no equivalent for folders.

My best attempt:

function getFolder(photo)
    local path = photo:getRawMetadata("path")
    local _, _, folderPath, filename = string.find(path, "^(.*)/([^/]*)$")
    return catalog:getFolderByPath(folderPath)
end

The string processing is non-portable (assumes "/" as path separator) and krufty. It would help if there were a LrFileUtils.parentDirectory function, but there is not.

Is there anything in the API to improve on this?

Use LrPathUtils to get the parent directory:

catalog:getFolderByPath (LrPathUtils.parent (photo:getRawMetadata ("path")))
