Subject: Re: Pre-fill Attribute with last entry 

Sorry Stefan, but it is possible as you have the scripting ability.

The idea is to use "Preset Test_Attribute = $shell(script_to_get_the_last_entry)", where the script asks elog about the details and parses them.
The problem here is, that the elogd already is working to resolve the click on "new entry" request (or similar) and the script can't call elogd until the page is delievered, what is to late.
(If it would, the elogd will hang.)

So the script either has to directly parse all the entry.log files in the logbook folder or you need a second elogd running, which can answer the request from the script.
This second elogd could run on a different port and it doen't need to be public as it only answers internal requests and could use the same config as the "primary" elogd.
My idea for the script uses the python elog module to establish the connection and do the parsing.

I hope this helps as a workaround.
Best wishes,
Sebastian

Nope, there is no way to acces the last value of an attribute. Sorry.

Hi all together,

I struggle a lot with the following problem:
I try to prefill certain attributes with the value of exactly the same attribute in the last entry made in the same logbook.

I know I have to go with Preset, tried a view hours and searched the forum but i didn't find a thing. Am I overlooking a flag, an option or whatever, or is there just not such a functionality (which I dont believe)?

I thought about:
Preset Test_Attribute = $Test_attribute
Preset Test_Attribute = Re:$Test_attribute
Preset Test_Attribute = $shell(Command to somehow get last entry and this attributes value)
Not succesful though.

I would be very thankful for help, thanks in advance.
