After upgrading to V2 and migrating all notes (adding an automatic ID property with org-id-get-create) and moving the Aliases inside the property drawer, I get some strange behaviour: - Updating the db runs fine, no errors. All files are cached - org-roam buffer with backlinks works - newly created notes can be linked and traversed to - org-roam find node works However, all previously exisiting notes cannot be retrieved when clicked on links. Emacs throws an "Cannot find entry with ID: “XXXXXX” error, which is clearly an org-id error. I thought org-roam somehow overrides org-id link functionality? Where does this happen in the code? Or am I mistaken here and I need to rely on org-id-locations and add the full org-roam folder to the org-id-extra-files? ---

I have the same exact problem, for old notes I need to delete the id and create it again for the links to work. Pretty manual but I have to manually change all the file links for id links anyways. I guess I should try to create some elisp to perform this automatically ---

> [@S\_Fabris](#): > > I thought org-roam somehow overrides org-id link functionality? Where does this happen in the code? It happened in the v1 in the function `org-roam-link-follow-link`: ```elisp (defun org-roam-link-follow-link (_path) ... (pcase-let ((`(,link-type ,loc ,desc ,mkr) (org-roam-link--get-location))) ... ("id" (org-goto-marker-or-bmk mkr))))) ``` It does not happen in v2 anymore: ```elisp (defun org-roam-link-follow-link (path) ... (pcase-let ((`(,id ,file ,pos) (org-roam-link-locate))) ... (org-id-goto id))) ``` So I guess one has to rely on `org-id-locations`. This could help find all the already existing relevant files: ```elisp (setq org-id-extra-files (find-lisp-find-files org-roam-directory "\.org$")) ``` ---

@S_Fabris @spicy In addition to @mshevchuk’s suggestion, this function might also work to update the org-id-locations. [Source here](https://org-roam.discourse.group/t/nroam-org-roam-backlinks-within-org-mode-buffers/1306/2). ```auto (org-id-update-id-locations (org-roam--list-all-files)) ``` I have functions out of this principle: ```auto (defun my/org-id-update-org-roam-files () "Update Org-ID locations for all Org-roam files." (interactive) (org-id-update-id-locations (org-roam--list-all-files))) (defun my/org-id-update-id-current-file () "Scan the current buffer for Org-ID locations and update them." (interactive) (org-id-update-id-locations (list (buffer-file-name (current-buffer))))) ``` ---

@nobiot’s is a better approach. ---

@nobiot ```auto (org-id-update-id-locations (org-roam--list-all-files)) ``` This worked. Now all IDs are cached and work independently of org-roam. This adds a second cache of all links and creates redundancy. This is good and bad at the same time: Good, because links will always work. Bad because two caches/databases need to be maintained. I wonder if it would be faster to use the org-roam db for inter-file linking for simplicity and only fall back on org-id if the notes are used without org-roam. ---

> [@S\_Fabris](#): > > I wonder if it would be faster to use the org-roam db for inter-file linking for simplicity This is the opposite to simplicity from the developer’s perspective. The new function is simpler than the old one and Org-roam does not have to care about how links work instead relying on the built-in mechanism, which is arguably more robust because a special effort is dedicated to it by Org maintainers. What Org-roam could do and I’m almost positive will do is provide a way to automatically update `org-id` database during initialization and whenever a note is created. ---

> [@mshevchuk](#): > > What Org-roam could do and I’m almost positive will do is provide a way to automatically update `org-id` database during initialization and whenever a note is created. This is what V2 does from what I have seen. It uses `org-id-get-create` during the capture process, so the ID gets generated and cached in the Org-ID way. > [@S\_Fabris](#): > > Bad because two caches/databases need to be maintained. You should not have had to update the ID locations for V1 org files, because the Org-ID cache would not have been influenced by going from Org-roam V1 to V2. The only reasons I could think of why you had to do it are: 1. You used to generate Org-ID manually, without using the `org-id-get-create` command, and other Org-ID commands. 2. You moved Org-roam files/directory outside Emacs ---

You moved Org-roam files/directory outside Emacs I’ve been trying to figure out why I’m getting errors when I run @jethro and @d12frosted 's conversion script, and after finding this thread I realize it’s because I’ve done both 1. and 2. above. 1. I have had capture templates that create file-level ID properties for while. Once I learned that org-roam v2 was going to make use of them, I started including them in all my new notes, but now I realize that org-id was unaware of them. 2. In order to achieve my desire to have some org-roam files of a non-work nature only on my personal laptop, some org-roam files of a work nature only on my work laptop, and a third category of files that are useful both at work and at home, I moved files around and into 3 different repos, thinking all I needed to do was re-synch the Roam DB and I would be good. But I guess I left org-id out of the loop, so it was missing all those changes too. ---

Hi All, I’m trying to follow this along and running into an error when setting the variable - `(setq org-id-extra-files (find-lisp-find-files org-roam-directory "\.org$"))` . Specifically - `(void-function find-lisp-find-files)`. Is this a known issue? Trying to find the `find-lisp-find-files` function seems to result in an error on this end, am I missing a package? Is there a way around that? I’m running Doom emacs if that helps. ---

It’s an old [built-in library](https://github.com/emacs-mirror/emacs/blob/master/lisp/find-lisp.el) so you should have it installed in your Emacs. You can check it by looking for `find-lisp-find-dired` (it’s flagged as autoload so you can see it before loading the library). Require or load-library `find-lisp`. You should see the function you are looking for. Alternatively, you could try `directory-files-recursively`. Refer below. [SlackExchange answer](https://stackoverflow.com/questions/11384516/how-to-make-all-org-files-under-a-folder-added-in-agenda-list-automatically#11384907) > **Edit:** (2019) As mentioned in the answer by @mingwei-zhang and the comment by @xiaobing, `find-lisp-find-files` from `find-lisp` and `directory-files-recursively` also provides this functionality. However, please note in these cases the file name argument is a (greedy) regex. So something like `(directory-files-recursively "~/my-dir" "org")` will give you all Org files including backup files ( `*.org~` ). To include only `*.org` files, you may use `(directory-files-recursively "~/my-dir" "org$")` . ---

Thanks very much for the solution, Nobiot! For those looking at this past Dec 28 2021, the function `org-roam--list-all-files` is now `org-roam-list-files`. ---

Think I had the same problem. Roam worked fine but exporting to html complained about missing IDs. Running `org-roam-update-org-id-locations` helped. Also hi.
