icon1.gif   Author special characters changed when saving as draft, posted by Víctor M. Nouvilas on Mon Dec 16 15:26:26 2024 

Hello, I have installed ELOG in an Ubuntu 22.04 machine and is working great, but I have found a small bug with Author names.

I have the config set like this for the Author attribute:

Preset Author = $long_name
Locked Attributes = Author

For context, my name is Víctor, which includes the accented "í". When creating a new entry and submitting immediately seems to work well. However, if I create a new entry, save it as draft, go back to the list, and then go to the draft entry, the accented "í" has transformed into "Ã". If I repeat the process, it turns into "ÃÂ", and so on. As I have configured the Author to not be editable, the user cannot fix this manually.

I found a way around this bug by setting

Subst Author = $long_name

Which is okay for us, but might not be for everyone.

In fact I saved this entry as a draft and then on another tab tried to edit it and it wouldn't let me edit because the author name now did not match.

Apparently Codecogs have changed their URL. I tried the update from 

  https://editor.codecogs.com/depr/CK_Editor_v4x.php

but it did not help. The CK Editor v5 is quite different from v4 (like they require node.js to install it), so putting it into elog would be some major work.

is there any update on this bug? Has anyone else observed the same problem?

Hi!

I am not sure if this is a know issue: it seems that the equation editor does not work anymore. Is there any fix or alternative method to type latex formula in the log? 

Thank you!

I built from source (ELOG V3.1.5-3a5f2f00) and I confirmed as fixed.

Alternatively, you can compile from sources. Give it a try.

It is in the usual download area which is referenced at https://elog.psi.ch/elog/download.html

icon4.gif   Webserver authentication may cause redirect loop, posted by Arjan Hulsbosch on Thu Jan 23 11:32:05 2025 

If

  1. Elog is configured to use webserver authentication, and
  2. the user reported by the webserver does not exist in the password file, and
  3. the "Guest Menu commands" configuration is set in "elogd.cfg", and
  4. a logbook is accessed,

then Elog returns with a redirect (302) to the logbook itself, causing the loop.

The fix here is to remove the "Guest Menu commands" configuration from "elogd.cfg".

Source code location: https://bitbucket.org/ritt/elog/src/30ada1df634529c8011c27275c52a05b01b7b3d6/src/elogd.cxx#lines-27599

icon4.gif   3-level conditional not working, posted by Harry Martin on Thu Mar 20 07:34:24 2025 

Not sure if this is a bug or not; if it is not, kindly reclassify the category.

Following is a small example of what I will dub a 3-level, conditional logbook:

[cond_test]
attributes = region, manufacturer, model

show attributes edit = region
options region = american{1}, japanese{2}, european{3}

{1} options manufacturer = ford, chrysler, gm
{2} options manufacturer = toyota{4}, nissan{5}, mitsubishi{6}
{3} options manufacturer = audi, mercedes, bmw, volvo, fiat
{1,2,3} show attributes edit = region, manufacturer
{4} options model = corolla, prius, miata
{5} options model = sentra, murano
{6} options model = starion, outlander, mirage
{4,5,6} show attributes edit = region, manufacturer, model

This example is hardly complete, but it is sufficient to demonstrate the issue I am running into.  This works until I select from the 2nd level (manufacturer); it won't display the dropdown for the model (I think my show attribute edit is supposed to display that).  Is there a restriction on how many levels of conditional I can have?  If there is, it would be disappointing because I am trying to do something similar to this example.

I hope there is something very simple I can do to correct this, or perhaps a completely different approach that accomplishes the same thing.  I'd like to stick with the multi-level selection process as I have done here.

I am running elog 3.1.5 on Devuan Chimaera (approx. Debian Bullseye, sans systemd) in a Virtualbox VM.

icon4.gif   New elog from template should update the subdir, posted by Liam Gaffney on Wed Apr 2 13:01:34 2025 

Hello. We are using explicity subdir names on our elog server to manage a large number of "Top groups" and sub "groups". When we create a new logbook from a template in the same group, it would be beneficial to automatically give a new subdir based on the previous one. At the very least, it should not reuse the same parameter as the template (see below).

At the moment, it copies the subdir parameter from the template logbook, which results in the new logbook writing to the same location as the template. That is very confusing and has the potential to be harmful as people can (and recently did) decide to delete these "duplicate" entries. But they are not duplicates, they are the exact same entries as the template logbook and deleting them removes them forever!

The way around this at the moment is to manually update the subdir after copying, but then the logbooks need to be re-indexed before the new logbook will display correctly. That requires a manual restart of the elogd process, which is less than ideal.
